Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-Degenerate Double-Detonation Type Ia Supernovae
Ken J. Shen, Douglas Boubert, Boris T. Gänsicke +23
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progeni…
BRITE-Constellation high-precision time-dependent photometry of the early-O-type supergiant Puppis unveils the photospheric drivers of its small- and large-scale wind structures
Tahina Ramiaramanantsoa, Anthony F. J. Moffat, Robert Harmon +33
From months of dual-band optical photometric monitoring at the mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star …
The variability of the BRITE-est Wolf-Rayet binary, Velorum I. Photometric and spectroscopic evidence for colliding winds
Noel D. Richardson, Christopher M. P. Russell, Lucas St-Jean +26
We report on the first multi-color precision light curve of the bright Wolf-Rayet binary Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation…
X-ray observations of FO Aqr during the 2016 low state
M. R. Kennedy, P. M. Garnavich, C. Littlefield +5
We present the first ever X-ray data taken of an intermediate polar, FO Aqr, when in a low accretion state and during the subsequent recovery. The Swift and Chandra X-ray data take…
The double-degenerate, super-Chandrasekhar nucleus of the planetary nebula Henize 2-428
M. Santander-García, P. Rodríguez-Gil, R. L. M. Corradi +5
The planetary nebula (PN) stage is the ultimate fate of stars with mass 1 to 8 solar masses (M). The origin of their complex morphologies is poorly understood, although sev…
High-speed photometry of faint cataclysmic variables - VIII. Targets from the Catalina Real-time Transient Survey
D. L. Coppejans, P. A. Woudt, B. Warner +7
Time series photometry of 20 Cataclysmic Variables detected by the Catalina Real-time Transient Survey is presented. 14 of these systems have not been observed previously and only…
Possible detection of two giant extrasolar planets orbiting the eclipsing polar UZ Fornacis
Stephen B. Potter, Encarni Romero--Colmenero, Gavin Ramsay +11
We present new high-speed, multi-observatory, multi-instrument photometry of the eclipsing polar UZ For in order to measure precise mid-eclipse times with the aim of detecting any…
