Abstract:
We present stellar parameter estimates for 939457 southern FGK stars
that are candidate targets for the Transiting Exoplanet Survey
Satellite (TESS) mission. Using a data-driven method similar to the
CANNON, we build a model of stellar colours as a function of stellar
parameters. We then use these in combination with stellar evolution
models to estimate the effective temperature, gravity, metallicity,
mass, radius, and extinction for our selected targets. Our effective
temperature estimates compare well with those from spectroscopic
surveys and the addition of Gaia DR2 parallaxes allows us to identify
subgiant interlopers into the TESS sample. We are able to estimate the
radii of TESS targets with a typical uncertainty of 9.3 per cent.
This catalogue can be used to screen exoplanet candidates from TESS
and provides a homogeneous set of stellar parameters for statistical
studies.
