A Brown Dwarf Orbiting around the Planetary-nebula Central Binary KV Vel

open access: yesThe Astrophysical Journal
KV Vel is a noneclipsing short-period ( P = 0.3571 days) close binary containing a very hot subdwarf primary (77,000 K) and a cool low-mass secondary star (3400 K) that is located at the center of the planetary nebula DS 1.

A Search for Subdwarf B Binaries Using Pulsation Timing from TESS

open access: yesThe Astronomical Journal
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 can be used via the timing method to test for companion stars and determine ...
