Abstract:
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission will
search for terrestrial planets in the habitable zone of solar-like stars.
Because of telemetry limitations PLATO targets need to be pre-selected. In
this paper we present an all sky catalog that will be fundamental to select
the best PLATO fields and the most promising target stars, derive their
fundamental parameters, analyze the instrumental performances and then plan
and optimize follow-up observations. This catalog also represents a valuable
resource for the general definition of stellar samples optimized for the
search of transiting planets. We used Gaia Data Release 2 (DR2) astrometry
and photometry and 3D maps of the local interstellar medium to isolate FGK
(V≤13) and M(V≤16) dwarfs and subgiant stars. We present the first public
release of the all sky PLATO Input Catalog (asPIC1.1) containing a total
of 2675539 stars among which 2378177 FGK dwarfs and subgiants and
297362 M dwarfs. The median distance in our sample is 428pc for FGK stars
and 146 pc for M dwarfs, respectively. We derived the reddening of our
targets and developed an algorithm to estimate stellar fundamental
parameters (Teff, radius, mass) from astrometric and photometric
measurements. We show that our overall (internal+external) uncertainties on
the stellar parameters determination is ∼230K (4%) for the effective
temperatures, ∼0.1R☉ (9%) for the stellar radii and ∼0.1M☉
(11%) for the stellar mass. We release a special target list
containing all known planet hosts cross-matched with our catalog.
Description:
The all sky PLATO Input Catalog (asPIC1.1) contains 2 675 539 entries
and 70 columns. The aspic1_1.dat size is ∼1.9GB.
