Abstract:
The Transiting Exoplanet Survey Satellite (TESS) will provide
high-precision time series photometry for millions of stars with at
least a half-hour cadence. Of particular interest are the circular
regions of 12° radius centred around the ecliptic poles that will
be observed continuously for a full year. Spectroscopic stellar
parameters are desirable to characterize and select suitable targets
for TESS, whether they are focused on exploring exoplanets, stellar
astrophysics or Galactic archaeology. Here, we present spectroscopic
stellar parameters (Teff, logg, [Fe/H], vsini, vmicro) for about 16000
dwarf and subgiant stars in TESS' southern continuous viewing zone.
For almost all the stars, we also present Bayesian estimates of
stellar properties including distance, extinction, mass, radius and
age using theoretical isochrones. Stellar surface gravity and radius
are made available for an additional set of roughly 8500 red giants.
All our target stars are in the range 10<V<13.1. Among them, we
identify and list 227 stars belonging to the Large Magellanic Cloud.
The data were taken using the High Efficiency and Resolution
Multi-Element Spectrograph (HERMES; R∼28000) at the Anglo-Australian
Telescope as part of the TESS-HERMES survey. Comparing our results
with the TESS Input Catalogue (TIC) shows that the TIC is generally
efficient in separating dwarfs and giants, but it has flagged more
than 100 cool dwarfs (Teff<4800K) as giants, which ought to be
high-priority targets for the exoplanet search. The catalogue can be
accessed via http://www.physics.usyd.edu.au/tess-hermes/, or at
Mikulski Archive for Space Telescopes (MAST).
Description:
The observations were obtained with the 4-m AAT located at Siding
Spring Observatory in Australia. We use the High Efficiency and
Resolution Multi-Element Spectrograph (HERMES), which can obtain
spectra of up to 360 science targets simultaneously.
We find that our catalogue of spectroscopic results is magnitude
complete down to 12.1mag in the TESS band for stars hotter than
4800K. In addition to spectroscopic values, we also provide
fundamental stellar properties inferred from the Bayesian
isochrone-based scheme, BSTEP.
