A spectroscopic and kinematic survey of fast hot subdwarfs
S. Geier, U. Heber, A. Irrgang +19
Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed by binary interactions. Close hot subdwarf binaries with massive white dwarf companions have been proposed…
Hot Subdwarfs in Close Binaries Observed from Space III: Reflection Effect Asymmetry Induced by Relativistic Beaming
Brad N. Barlow, Thomas Kupfer, Bryce A. Smith +2
Detailed studies of hot subdwarf B stars with red dwarf or brown dwarf companions can shed light on the effects of binarity on late stellar evolution. Such systems exhibit a strong…
An Eclipsing 47 minute Double White Dwarf Binary at 400 pc
James Munday, P. -E. Tremblay, J. J. Hermes +20
We present the discovery of the eclipsing double white dwarf (WD) binary WDJ 022558.21-692025.38 that has an orbital period of 47.19 min. Following identification with the Transiti…
Hot subdwarfs in close binaries observed from space II: Analysis of the light curves
V. Schaffenroth, B. N. Barlow, I. Pelisoli +2
Hot subdwarfs in close binaries with either M dwarf, brown dwarf or white dwarf companions show unique light variations. In hot subdwarf binaries with M dwarf or brown dwarf compan…
V907 Sco Switched to the Eclipsing Mode Again
P. Zasche, D. Vokrouhlický, B. N. Barlow +1
V907 Scorpii is a unique triple system in which the inner binary component has been reported to have switched on and off eclipses several times in modern history. In spite of its p…
Pulse Timing Discovery of a Three-Day Companion to the Hot Subdwarf BPM 36430
Bryce A. Smith, Brad N. Barlow, Benjamin Rosenthal +2
Hot subdwarf B stars are core-helium burning objects that have undergone envelope stripping, likely by a binary companion. Using high-speed photometry from the Transiting Exoplanet…
