Coverage of 6 YSOs needed in May for HST observations
Active Dates: April 29, 2022 – May 14, 2022
Abstract:
Dr. Frederick Walter (Stonybrook University) requests AAVSO observers' assistance in monitoring six T Tau stars in support of HST observations scheduled for May 2022. As part of the HST ULLYSES program (which is part of the larger ODYSSEUS program), the HST is scheduled to obtain UV spectra of these accreting T Tauri stars. It would be helpful to have BVRI photometry for them in order to help interpret the UV spectra.
Justification:
It would be helpful to have BVRI photometry for the target stars in order to help interpret the UV spectra from HST observations.
