Abstract:
The demographics of young exoplanets can shed light on their formation
and evolution processes. Exoplanet properties are derived from the
properties of their host stars. As such, it is important to accurately
characterize the host stars since any systematic biases in their
derivation can negatively impact the derivation of planetary
properties. Here we present a uniform catalog of photometrically
derived stellar effective temperatures, luminosities, radii, and
masses for 4865 young (<1Gyr) stars in 31 nearby clusters and moving
groups within 200pc. We compared our photometrically derived
properties to a subset of those derived from spectra and found them to
be in good agreement. We also investigated the effect of stellar
properties on the detection efficiency of transiting short-period
young planets with TESS as calculated in Fernandes et al. (2022) and
found an overall increase in the detection efficiency when the new
photometrically derived properties were taken into account. Most
notably, there is a 1.5x increase in the detection efficiencies for
sub-Neptunes/Neptunes (1.8-6R⊕) implying that, for our sample
of young stars, better characterization of host star properties can
lead to the recovery of more small transiting planets. Our
homogeneously derived catalog of updated stellar properties, along
with a larger unbiased stellar sample and more detections of young
planets, will be a crucial input to the accurate estimation of the
occurrence rates of young short-period planets.
Description:
In this paper, we used Gaia and 2MASS photometry along with stellar
(magnetic and nonmagnetic) isochrones in order to derive a homogeneous
set of stellar properties, specifically Teff, L*, R*, and M* for
4865 stars
