X-ray observation of the Roche-lobe filling white dwarf plus hot subdwarf system ZTF J213056.71+442046.5
S. Mereghetti, N. La Palombara, T. Kupfer +9
ZTF J213056.71+442046.5 is the prototype of a small class of recently discovered compact binaries composed of a white dwarf and a hot subdwarf that fills its Roche-lobe. Its orbita…
A hot subdwarf-white dwarf super-Chandrasekhar candidate supernova Ia progenitor
Ingrid Pelisoli, P. Neunteufel, S. Geier +8
Supernova Ia are bright explosive events that can be used to estimate cosmological distances, allowing us to study the expansion of the Universe. They are understood to result from…
ZTFJ0038+2030: a long period eclipsing white dwarf and a substellar companion
Jan van Roestel, Thomas Kupfer, Keaton J. Bell +11
In a search for eclipsing white dwarfs using the Zwicky Transient Facility lightcurves, we identified a deep eclipsing white dwarf with a dark, substellar companion. The lack of an…
A systematic search for outbursting AM CVn systems with the Zwicky Transient Facility
Jan van Roestel, Leah Creter, Thomas Kupfer +15
AM CVn systems are a rare type of accreting binary that consists of a white dwarf and a helium-rich, degenerate donor star. Using the Zwicky Transient Facility (ZTF), we searched f…
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…
HO Puppis: Not a Be Star but a Newly Confirmed IW And-Type Star
Chien-De Lee, Jia-Yu Ou, Po-Chieh Yu +19
HO Puppis (HO Pup) was considered as a Be-star candidate based on its gamma-Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia D…
