Binary Systems Search with TESS
Tomomi Otani, A. S. Baran, Lindsay C. Spence +3
Hot subdwarf B (sdB) stars are post-main-sequence stars of high temperature and gravity. Approximately 30 of sdBs exhibit stable pressure and/or gravity-mode pulsations, which…

The EXOTIME project: Signals in the diagrams of the rapidly pulsating subdwarfs DW Lyn, V1636 Ori, QQ Vir, and V541 Hya
F. Mackebrandt, S. Schuh, R. Silvotti +17
We aim to investigate variations in the arrival time of coherent stellar pulsations due to the light-travel time effect to test for the presence of sub-stellar companions. Those co…

Orbital Characteristics of the Subdwarf-B and F V Star Binary EC~20117-4014(=V4640 Sgr)
T. Otani, T. Oswalt, A. E. Lynas-Gray +4
Among the competing evolution theories for subdwarf-B (sdB) stars is the binary evolution scenario. EC~20117-4014 (=V4640~Sgr) is a spectroscopic binary system consisting of a puls…
