A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
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…
