Title: A Search For Flickering To Probe Accretion Activity And Binarity In Agb Stars

PI: Sahai, Raghvendra - NASA/Jpl

Type: N/A

Summary: Our X-ray surveys of a small sample of cool AGB stars with FUV excesses reveal X-ray emission in 40% of our sample. The X-ray emission shows the unexpected presence of magnetically-confined and very hot gas (Tx~35-150 MK), and quasi-periodic variations on hour-long timescales, likely associated with an accretion disk around a main-sequence companion. Recent HST UV observations show flickering on ~minute time-scales for our key fuvAGB object, confirming the presence of an accretion disk. We propose a TESS survey to search for such fast variations in TESS's optical band for a statistical sample of AGB stars with UV emission. The resulting database of high-cadence, high-sensitivity light curves will provide an unprecedented window into binary interactions in AGB stars.
