A machine learning approach to photometric metallicities of giant stars
Connor P. Fallows, Jason L. Sanders
Despite the advances provided by large-scale photometric surveys, stellar features - such as metallicity - generally remain limited to spectroscopic observations often of bright, n…
Evidence for sub-Chandrasekhar Type Ia supernovae from the last major merger
Jason L. Sanders, Vasily Belokurov, Kai T. F. Man
We investigate the contribution of sub-Chandrasekhar mass Type Ia supernovae to the chemical enrichment of the Gaia Sausage galaxy, the progenitor of a significant merger event in…
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…
Keeping it Cool: Much Orbit Migration, yet Little Heating, in the Galactic Disk
Neige Frankel, Jason Sanders, Yuan-Sen Ting +1
A star in the Milky Way's disk can now be at a Galactocentric radius quite distant from its birth radius for two reasons: either its orbit has become eccentric through radial heati…
Models of Bars with Exponential Density Profiles
D. P. McGough, N. W. Evans, J. L. Sanders
We present a new model for galactic bars with exponentially falling major axis luminosity profiles and Gaussian cross-sections. This is based on the linear superposition of Gaussia…
The total stellar halo mass of the Milky Way
Alis J. Deason, Vasily Belokurov, Jason L. Sanders
We measure the total stellar halo luminosity using red giant branch (RGB) stars selected from Gaia data release 2. Using slices in magnitude, colour and location on the sky, we dec…
