Kelley PROGRAM_INV3 Bin Yang PROGRAM_INV4 PROGRAM_INV5 PROGRAM_SCICAT solar system PROGRAM_ABSTRACT_BEG We propose to characterize the water-ice properties of a cometary outburst in 2021B with IRTF/SpeX. Our project would observe the aftermath of a comet outburst, fragmentation, or disintegration event and compare its reflectance spectrum to those of comets in quiescent activity. Our ultimate goal is testing the heterogeneity of water ice in cometary nuclei and understand which properties of comets are primitive, and which are evolutionary. PROGRAM_ABSTRACT_END
