Predictions of Gaia's prize microlensing events are flawed
Peter McGill, Andrew Everall, Douglas Boubert +1
Precision astrometry from the second Gaia data release has allowed astronomers to predict 5,787 microlensing events, with 528 of these having maximums within the extended Gaia miss…
Kinematic study of the association Cyg OB3 with Gaia DR2
Anjali Rao, Poshak Gandhi, Christian Knigge +3
We study the stellar kinematic properties and spatial distribution of the association Cyg OB3 using precise astrometric data from Gaia DR2. All known O- and B-type stars in Cyg OB3…
Lessons from the curious case of the `fastest' star in Gaia DR2
Douglas Boubert, Jay Strader, David Aguado +6
Gaia DR2 5932173855446728064 was recently proposed to be unbound from the Milky Way based on the median radial velocity given in Gaia D…
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…
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…
