Tuesday 26th to Friday 29th of JUNE, 2007




The CD07 workshop is organized by:
Adriano Campo Bagatin (Universidad de Alicante, Spain)
Bobby Bus (University of Hawaii, USA)
Dan Durda (Southwest Research Institute, Boulder CO, USA)
Patrick Michel (Observatoire de la Cote d'Azur, Nice, France)

Adriano Campo Bagatin (Universidad de Alicante), along with a local staff, will take care of local arrangements, gourmet feasting, and will be the conference administrator.

Our Scientific Organizing Committee is composed by the four organizers plus:
Erik Asphaug (University of California at Santa Cruz, USA)
Alberto Cellino (Osservatorio Astronomico di Torino, Italy)
Kevin Housen (Boeing Company, Seattle WA, USA)
Akiko Nakamura (Kobe University, Japan)


In the tradition and spirit of past Catastrophic Disruption Workshops, CD07 aims to bring together people working on all topics related to collisions between small Solar System bodies: laboratory experiments, internal structures, rotations, binaries, asteroid families, numerical modeling, interpretation of data from small body space missions, and calibrations for new missions, such as Don Quijote (ESA, a test of asteroid deflection strategies) and Hayabusa (JAXA, a sample-return mission). A number of specialists, young researchers and students in this field will have the opportunity to present their work and broadly discuss these topics. The workshop will take place over 4 days, with seven half-day sessions, three social events, and one free afternoon. The format and pace of the meeting will be relatively relaxed and should stimulate open discussion - the most important aspect of this kind of meeting.

In order to allow fruitful discussions and be able to fit into the conference hall, the number of participants will be limited to about 75.

Participation of young researchers (including Ph.D. students) in the field is strongly encouraged as a source of fresh ideas.

There will be no poster session.

Contributed talks will be given 20 minutes with 10 minutes for questions and discussion, and invited reviews (IR) will have 40-45 minutes with 10-15 minutes for discussion. In this format, we will have a dozen invited reviews and some 20 contributed talks. It will be possible to arrange some "back to back" communications (both for IR and contributed talks) if the topics are closely related and the authors agree.

Confirmed invited speakers:

Akira Fujiwara (Institute of Space and Astronautical Science - JAXA, Japan)
Keith Holsapple (University of Washington, USA)

Monday 25th, 19:00 to 22:00: Welcoming reception at Hotel Spa Porta Maris. In order to properly organize this event, please let us know if your arrival time will allow you to participate. We understand that this information may not be available until you finalize your travel plans. However, we would greatly appreciate any information you can provide about your arrival in Alicante by the end of May.

Wednesday 27th, 13:30: Trip to Tabarca Island by an absolutely safe hydrofoil ship (40 minute sailing) and lunch in a typical restaurant, featuring "Caldero", a local specialty based on a local fish and a very good paella. The afternoon is free, allowing the possibility to go back to Alicante or to spend the entire afternoon on the Island. Tabarca Island is a natural reserve and it has many small beaches for sunbathing (take care, as the "Tabarca Sun" is known for its special tanning power!), meditation and relaxation, swimming and snorkeling. Fishing is forbidden along much of its coastline. THIS TRIP IS HIGHLY RECOMMENDED. Please let us know if you plan to participate in the "Social events grid" at the end of this message. Your response on this form is not binding, but helps give us an idea of the number of people interested in this trip. We will need to have a final head count of people wanting to participate in this event by the end of May.

Thursday 28th, 21:30: Conference dinner at a local restaurant. Please let us know if you plan to participate in the "Social events grid" below. Your response is not binding, but provides an idea of the number of interested people. Again, we will need you to make up your mind by the end of May.

On Tuesday 26th or Friday 29th, around 20:00, at the downtown University Centre (a 10 minute walk from the Hotel), we would like to organize an informative talk about fragmentation phenomena or collisions in general, space missions to asteroids, or any other topics related to the CD07 workshop. The speaker should be one of the non-local participants at the workshop, and the talk should be given in Spanish (or Spanglish, at least...). VOLUNTEERS ARE NEEDED. Please let us know if you wish to help out. In return, the speaker will receive an exemption from paying the CD07 registration fee.

We hope we may offer all social events free of charge, once we have confirmation of funding from all our sponsors. In particular, the Tabarca Island trip and lunch will be available to any Workshop participant (including guests) at a fixed rate that, in the worst case, will not exceed 50 Euros per person (payable on site).


Alicante is situated on the south-eastern coast of Spain, in the region called 'Comunidad Valenciana', on the shore of the Mediterranean Sea. Founded by the Greeks (Akra Leuka) and dominated by the Romans (Lucentum), both cultures named it, in ancient times, 'the city of light', for the many days of sunshine per year. Now it is often referred to as 'the Spring's home' due to its mild weather, both in winter and in summer. You can learn more about Alicante and the sights it offers at, and the surrounding area at As a Mediterranean town, Alicante has a multi-ethnic cultural and social life, with more than 300,000 inhabitants representing 140 different nationalities, all living together in good harmony. Alicante is the European province with the highest ratio of resident people from other European countries (around 10% of the total population).

Alicante has a modern, mid-size (for Spain) university (, with approximately 30,000 students. The Departamento de Fisica, Ingenieria de Sistema y Teoria de la Senal (Department of Physics, Systems Engineering and Signal Theory) of the Universidad de Alicante is formally organizing this meeting. Our Department has a small research group in Astronomy and Astrophysics, composed of 7 members plus three undergraduate students.

Tourist Attractions: Tens of kilometers of beaches are not the only tourist attraction on the 'Costa Blanca', as this part of the Mediterranean coast is named. Medieval history is present in town with two ancient castles (one in very good condition: 'Santa Barbara' castle) and a few more within a distance of 50 km. Roman ruins are also present in town and in a 'villa' located in a pretty village only 15 minutes away by a modern tram that runs north along the coast. It is also possible to visit picturesque Tabarca island - a natural marine reserve - where one can escape from the crowds and traffic, and taste the flavors of the local cuisine. Getting to Tabarca Island takes less than one hour of sailing on the quiet Mediterranean Sea ( Altea, Benidorm, Guadalest, Benissa, Calpe, and two natural caves are just some of the places that can also be visited.

Important Tip: From the 20th until the 24th of June, the town celebrates a magical period with its main festival of the year: "Les Fogueres de San Juan", a traditional feast full of music, shows, noise and fire! If you wish to experience it, just let the hotel know how many nights you would like to extend your stay, and they will offer the same room rate if the extension is limited to a few days.

You may wish to spend a few days in Spain before or after the meeting to explore other parts of the country. Spain, like other European countries, offers many historical locations, such as Toledo, Segovia, Cordova, Granada, and Salamanca. If you are not sure about how to plan your visit, please do not hesitate to drop us a line and tell us what you are interested in seeing. We will try to offer suggestions to help you make the best of your holiday.


The easiest way to reach Alicante from abroad is by plane. Alicante airport ("El Altet") is a busy airport, with a bunch of low-cost airlines offering service to many cities in Europe. Frequent flights from/to Madrid and Barcelona are available every day for passengers coming from outside Europe. Taxis from the airport will take you to the Hotel Spa Porta Maris for about 15 Euros. A bus also runs from/to the airport to downtown, a 10 minute walk from the workshop hotel. As usual, the sooner you book your flights, the cheaper.

Regular comfortable trains also travel to Alicante from Madrid and Barcelona. (

A car is not really necessary for a one-week stay in Alicante, but if you like to drive, Alicante is connected by highway to the rest of Spain and Europe. You can easily rent a car at the airport or even in downtown. The Spanish driving (and parking) style and traffic density is comparable to (that is, not worse than) that of Northern Italy or Southern France.


The workhop will be held at "HOTEL SPA PORTA MARIS" (, one of the newest and best placed hotels in town. This is a "three star" hotel, but keep in mind that Spanish standards in hotels are far better than in most other European countries (i.e.: typically a "three-star" hotel in Spain is equivalent , but far cheaper, than a "four-star" hotel in the rest of Europe). It offers "SPA" services (see rates on their web page).

We have blocked 60 rooms at this hotel until March 26th, 2007. After this deadline, rates remain the same, BUT availability is not guaranteed.

Double room: 103 Euros (+7% VAT)
Single room: 89 Euros (+7% VAT)

The "Hotel Spa Porta Maris" kindly offers the same rates to CD07 attendees who wish to stay a few days (3-4) before or after the workshop. Consider this unique opportunity to celebrate the "Fogueres de Sant Joan" while staying in a prime location.

Even though we strongly recommend staying at this hotel, many other fine lodging options are available in the downtown area, if you just want to be on your own. If your budget for lodging is way below the rates given above and you are not eligible for a grant, please let us know and we will suggest alternative accommodations.

It is possible to have lunch at the hotel at a rate of around 25 Euros, including drinks. It would be a fixed menu (not buffet), changing every day. The Hotel will need to know which days you would like to have lunch at the Hotel a couple of weeks before the beginning of the workshop (Please, remember we have scheduled the trip to Tabarca on Wednesday, June 27th). Many restaurants and bars are in the tourist area of the harbor, close to the hotel (a 5 minute walk), and downtown (a 10 minute walk, suitable for those colleagues used to walking under the summer sunshine at noon, around latitude 38°).
