TIC 378898110: A Bright, Short-Period AM CVn Binary in TESS
Matthew J. Green, J. J. Hermes, Brad N. Barlow +22
AM CVn-type systems are ultracompact, helium-accreting binary systems which are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong G…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with TESS: I. Asteroseismology of the GW Vir stars RX J2117+3412, HS 2324+3944, NGC 6905, NGC 1501, NGC 2371, and K 1-16
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +7
In this paper, we present a detailed asteroseismological analysis of six GW Vir stars including the observations collected by the TESS mission. We processed and analyzed TESS obser…
PHL 417: a zirconium-rich pulsating hot subdwarf (V366 Aquarid) discovered in K2 data
Roy Østensen, C. Simon Jeffery, Hideyuki Saio +6
The Kepler spacecraft observed the hot subdwarf star PHL 417 during its extended K2 mission, and the high-precision photometric lightcurve reveals the presence of 17 pulsation mode…
First Kepler results on compact pulsators VII. Pulsating subdwarf B stars detected in the second half of the survey phase
A. S. Baran, S. D. Kawaler, M. D. Reed +10
We present five new pulsating subdwarf B (sdB) stars discovered by the Kepler spacecraft during the asteroseismology survey phase. We perform time-series analysis on the nearly con…
First Kepler results on compact pulsators VIII: Mode identifications via period spacings in mode pulsating Subdwarf B stars
M. D. Reed, A. Baran, A. C. Quint +13
We investigate the possibility of nearly-equally spaced periods in 13 hot subdwarf B (sdB) stars observed with the Kepler spacecraft and one observed with CoRoT. Asymptotic limits…
First Kepler results on compact pulsators VI. Targets in the final half of the survey phase
R. H. Østensen, R. Silvotti, S. Charpinet +29
We present results from the final six months of a survey to search for pulsations in white dwarfs and hot subdwarf stars with the Kepler spacecraft. Spectroscopic observations are…
First Kepler results on compact pulsators II: KIC 010139564, a new pulsating subdwarf B (V361 Hya) star with an additional low-frequency mode
Steven D. Kawaler, M. D. Reed, A. C. Quint +13
We present the discovery of nonradial pulsations in a hot subdwarf B star based on 30.5 days of nearly continuous time-series photometry using the \emph{Kepler} spacecraft. KIC 010…
First Kepler results on compact pulsators III: Subdwarf B stars with V1093~Her and hybrid (DW~Lyn) type pulsations
M. D. Reed, S. D. Kawaler, R. H. Ostensen +12
We present the discovery of nonradial pulsations in five hot subdwarf B (sdB) stars based on 27 days of nearly continuous time-series photometry using the Kepler spacecraft. We fin…
First Kepler results on compact pulsators V: Slowly pulsating subdwarf B stars in short-period binaries
S. D. Kawaler, M. D. Reed, R. H. Østensen +15
The survey phase of the Kepler Mission includes a number of hot subdwarf B (sdB) stars to search for nonradial pulsations. We present our analysis of two sdB stars that are found t…
