Variable star classification across the Galactic bulge and disc with the VISTA Variables in the Vía Láctea survey
Thomas A. Molnar, Jason L. Sanders, Leigh C. Smith +3
We present VIVACE, the VIrac VAriable Classification Ensemble, a catalogue of variable stars extracted from an automated classification pipeline for the Vista Variables in the Vía…
VVV-WIT-08: the giant star that blinked
Leigh C. Smith, Sergey E. Koposov, Philip W. Lucas +11
We report the serendipitous discovery of a late-type giant star that exhibited a smooth, eclipse-like drop in flux to a depth of 97 per cent. Minimum flux occurred in April 2012 an…
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…
The asymptotic evolution of the stellar merger V1309 Sco: a Blue Straggler in the making?
Thiago Ferreira, Roberto K. Saito, Dante Minniti +4
Stellar mergers are estimated to be common events in the Galaxy. The best studied stellar merger case to date is V1309 Sco (= Nova Scorpii 2008) which was originally misclassified…
High Proper Motion Objects from the UKIDSS Galactic Plane Survey
L. Smith, P. W. Lucas, R. Bunce +12
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a 7 year effort to survey ~1800 square degrees of the northern Galactic plane in the J, H, and K passbands. The survey inclu…
The Kinematic Age of the Coolest T Dwarfs
Leigh Smith, Philip Lucas, Ben Burningham +5
Surprisingly, current atmospheric models suggest that the coolest T dwarfs (T8.5 to T10) are young and very low mass (0.06-2Gyr, 5-20Mjup, Leggett et al.2009, 2010, 2012). Studies…
