A study of transients from ground-based surveys reveals new ultra-compact accreting white dwarf binaries
Jan Kára, Liliana Rivera Sandoval, Wendy Mendoza +5
AM CVn stars are ultra-compact semi-detached binaries consisting of a white dwarf primary and a hydrogen-depleted secondary. In this paper we present spectroscopic and photometric…
Cataclysmic Variables in Triples: Formation Models and New Discoveries
Cheyanne Shariat, Kareem El-Badry, Smadar Naoz +2
The formation of cataclysmic variables (CVs) has long been modeled as a product of common envelope evolution (CEE) in isolated binaries. However, a significant fraction of intermed…
The OmegaWhite Survey for Short-Period Variable Stars VII: High amplitude, short period blue variables
G. Ramsay, P. A. Woudt, T. Kupfer +11
Blue Large Amplitude Pulsators (BLAPs) are a relatively new class of blue variable stars showing periodic variations in their light curves with periods shorter than a few tens of m…
Discovery and characterization of five new eclipsing AM CVn systems
J. van Roestel, T. Kupfer, M. J. Green +19
AM CVn systems are ultra-compact, helium-rich, accreting binaries with degenerate or semi-degenerate donors. We report the discovery of five new eclipsing AM CVn systems with orbit…
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…
An Outburst by AM CVn binary SDSS J113732.32+405458.3
Tin Long Sunny Wong, Jan van Roestel, Thomas Kupfer +1
We report the discovery of a one magnitude increase in the optical brightness of the 59.63 minute orbital period AM CVn binary SDSS J113732.32+405458.3. Public , , and ba…
Cataclysmic Variables in the First Year of the Zwicky Transient Facility
Paula Szkody, Brooke Dicenzo, Anna Y. Q. Ho +25
Using selection criteria based on amplitude, time and color, we have identified 329 objects as known or candidate cataclysmic variable (CVs) during the first year of testing and op…
