The quick and the dead: Finding the surviving binary companions of Galactic supernovae with Gaia
M. Fraser, D. Boubert
We use Gaia Data Release 2 to search for possible surviving binary companions to three of the best studied historical Milky Way core-collapse supernovae. Consistent with previous w…
A hypervelocity star with a Magellanic origin
Denis Erkal, Douglas Boubert, Alessia Gualandris +2
Using proper motion measurements from Gaia DR2, we probe the origin of 26 previously known hypervelocity stars (HVSs) around the Milky Way. We find that a significant fraction of t…
On the kinematics of a runaway Be star population
Douglas Boubert, N. Wyn Evans
We explore the hypothesis that B type emission-line stars (Be stars) have their origin in mass-transfer binaries by measuring the fraction of runaway Be stars. We assemble the larg…
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…
Revisiting hypervelocity stars after Gaia DR2
Douglas Boubert, James Guillochon, Keith Hawkins +3
Hypervelocity stars are intriguing rare objects traveling at speeds large enough to be unbound from the Milky Way. Several mechanisms have been proposed for producing them, includi…
