# # Program information file # PROGRAM_ID 2022B989 PROGRAM_TITLE IR Spectral Atlas RW Aur PROGRAM_INV1 Eric Gaidos PROGRAM_INV2 PROGRAM_INV3 PROGRAM_INV4 PROGRAM_INV5 PROGRAM_SCICAT stellar PROGRAM_ABSTRACT_BEG We propose to obtain high-resolution JHKL iSHELL spectra of RW Aur simultaneously with TESS on the night of HST 7 Dec. We will measure the strength, centroid, and shape of emission lines and their variation, including those of Fe II and H I described by Lisse et al. (2022). We will repeat these observations twice to determine variability on the timescales of a few hours than can be correlated with the TESS lightcurve. PROGRAM_ABSTRACT_END
