Discovery of the first outbursting hot subdwarf binary: ZTF J0007+4804
E. Stringer, T. Kupfer, K. Deshmukh +10
Hot subdwarf binaries with white dwarf companions with orbital periods of less than two hours are progenitor candidates for massive single white dwarfs as well as a variety of ther…
Stars on the ascending helium giant branch I. From white dwarf merger to helium giant: the evolutionary state of the rapidly rotating hot subdwarf HE 1518-0948
M. Pritzkuleit, M. Dorsch, M. M. Miller Bertolami +3
Hot subdwarf stars with masses above ascend the helium giant branch after the end of core helium burning, before entering the white dwarf cooling track or exploding a…
Spectroscopic follow-up of hot subdwarf variables found in ZTF -- Atmospheric and fundamental properties of radial-mode sdB pulsators
Corey W. Bradshaw, Thomas Kupfer, Alekzander R. Kosakowski +2
Hot subdwarf variables (sdBVs) that display large-amplitude (1%), short-period variability, as a result of radial-mode pulsations, have recently become objects of interest as th…
OGLE-BLAP-009 -- A Case Study for the Properties and Evolution of Blue Large-Amplitude Pulsators
Corey W. Bradshaw, Matti Dorsch, Thomas Kupfer +5
Blue large-amplitude pulsators (BLAPs) make up a rare class of hot pulsating stars with effective temperatures of 30,000 K and surface gravities of 4.0 - 5.0 dex (cgs). Th…
Year 1 of the ZTF high-cadence Galactic Plane Survey: Strategy, goals, and early results on new single-mode hot subdwarf B-star pulsators
Thomas Kupfer, Thomas A. Prince, Jan van Roestel +18
We present the goals, strategy and first results of the high-cadence Galactic plane survey using the Zwicky Transient Facility (ZTF). The goal of the survey is to unveil the Galact…
Exploring the tilted accretion disc of AQ Men with TESS
Krystian Ilkiewicz, Simone Scaringi, James M. C. Court +8
AQ Men is a nova-like variable which is presumed to have a tilted, precessing accretion disc. Grazing eclipses in this system have been speculated to be useful in exploring the geo…
