This follows the historic dimming of the star captured by HST/STIS in 2019-2020, and will probe the unusual atmospheric structure following the dimming event. An HST campaign of 2 cycles will be complemented by multi-frequency photometry, spectroscopy, interferometry and polarimetry at radio, infrared, and optical wavelengths in order to map surface structures and their variability, and the extended outer atmosphere over both the short (420-day) and long, secondary (2000-day) periods of this supergiant. These observations, coupled with detailed modeling and simulations. will probe the structure, dynamics, and mass loss from Betelgeuse to provide crucial insights into the atmospheric physics and wind-driving mechanisms of red supergiants. ------------------------------------------------------------------------------------ Observations Description ------------------------ During Cycle 29 (the first cycle of a two cycle program), we will make 5 visits of 4 orbits each to the red supergiant Betelgeuse; visits spread over the times of target accessibility. Using the smallest aperture (0.025X0.1") of STIS, the 16655( 4) - 09-Mar-2023 18:28:21 - [ 2] NUV-MAMA E230M (2707) setting, we propose to obtain spectra at 5 positions on the ultraviolet image: center peakup, +/-25 mas, and +/-50 mas offsets. Exposure time at center: 2040 sec. Exposure times at +/-25 mas: 2520 - 3000 sec Exposure times at +/-50 mas: 600 sec We plan a tomographic analysis of the absorption line spectra at center, +/-25 mas, so require S/N ~ 50 at those positions. ------------------------------------------------------------------------------------ 16655( 4) - 09-Mar-2023 18:28:21 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HD39801 STAR, M III-I RA=05H55M10.3341S, J2000 V = 0.42 +/- 0.2 DEC=+07D24'25.61" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.This object was generated by the targetselector and retrieved from the SIMBAD database.This object was generated by the targetselector and retrieved from the SIMBAD database.
