Design of the Gaia photometric systems for stellar parametrization using a population-based optimizer
C. A. L. Bailer-Jones
Large, deep surveys must typically rely on multiband photometry rather than spectroscopy for determining the astrophysical properties (APs) of stars. Yet designing an optimal photo…

Object classification and the determination of stellar parameters with Gaia
C. A. L. Bailer-Jones
Gaia will observe more than one billion objects brighter than V=20, including stars, asteroids, galaxies and quasars. As Gaia performs real time detection (i.e. without an input ca…

Variability and rotation of ultra cool dwarfs
C. A. L. Bailer-Jones
Over the past few years monitoring programs have shown ultra cool dwarfs (UCDs) to be photometrically variable. Of the 60 sources monitored in the field and some 120 monitored in c…
