A new class of Roche lobe-filling hot subdwarf binaries
Thomas Kupfer, Evan B. Bauer, Kevin B. Burdge +30
We present the discovery of the second binary with a Roche lobe-filling hot subdwarf transferring mass to a white dwarf (WD) companion. This 56 minute binary was discovered using d…
ZTF J1901+5309: A 40.6-Minute Orbital Period Eclipsing Double White Dwarf System
Michael W. Coughlin, Kevin Burdge, E. Sterl Phinney +17
The Zwicky Transient Facility has begun to discover binary systems with orbital periods that are less than 1\,hr. Combined with dedicated follow-up systems, which allow for high-ca…
IGAPS: the merged IPHAS and UVEX optical surveys of theNorthern Galactic Plane
M. Monguió, R. Greimel, J. E. Drew +47
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003 an…
The first ultracompact Roche lobe-filling hot subdwarf binary
Thomas Kupfer, Evan B. Bauer, Thomas R. Marsh +29
We report the discovery of the first short period binary in which a hot subdwarf star (sdOB) fills its Roche lobe and started mass transfer to its companion. The object was discove…
Orbital Decay in a 20 Minute Orbital Period Detached Binary with a Hydrogen Poor Low Mass White Dwarf
Kevin B Burdge, Jim Fuller, E. Sterl Phinney +14
We report the discovery of a detached double white dwarf binary with an orbital period of , PTF J053332.05+020911.6. The visible object in this binary, PT…
Simultaneous observations of the northern TESS sectors by the Zwicky Transient Facility
Jan van Roestel, Eric C. Bellm, Dmitry A. Duev +9
The Zwicky Transient Facility (ZTF) is conducting a nightly public survey of all 13 TESS northern sectors in 2019-2020. ZTF will observe the portions of the current TESS sectors vi…
