Abstract:
The Kepler telescope has discovered over 4000 planets (candidates) by
searching ∼200000 stars over a wide range of distance (order of kpc)
in our Galaxy. Characterizing the kinematic properties (e.g., Galactic
component membership and kinematic age) of these Kepler targets
(including the planet candidate hosts) is the first step toward
studying Kepler planets in the Galactic context, which will reveal
fresh insights into planet formation and evolution. In this paper, the
second part of the Planets Across the Space and Time (PAST) series, by
combining the data from the Large Sky Area Multi-Object Fiber
Spectroscopic Telescope (LAMOST) and Gaia and then applying the
revised kinematic methods from PAST I, we present a catalog of
kinematic properties (i.e., Galactic positions, velocities, and the
relative membership probabilities among the thin disk, thick disk,
Hercules stream, and the halo) as well as other basic stellar
parameters for 35835 Kepler stars. Further analyses of the
LAMOST-Gaia-Kepler catalog demonstrate that our derived kinematic age
reveals the expected stellar activity-age trend. Furthermore, we find
that the fraction of thin (thick) disk stars increases (decreases)
with the transiting planet multiplicity (Np=0,1,2 and3+) and the
kinematic age decreases with Np, which could be a consequence of the
dynamical evolution of planetary architecture with age. The
LAMOST-Gaia-Kepler catalog will be useful for future studies on the
correlations between the exoplanet distributions and the stellar
Galactic environments as well as ages.
Description:
In this paper we construct a LAMOST-Gaia-Kepler catalog of 35835
Kepler stars kinematic properties as well as other basic stellar
properties by combining data from Gaia DR2 and LAMOST DR4. By adopting
the revised kinematic methods in PAST I (Chen+, 2021ApJ...909..115C 2021ApJ...909..115C),
we calculate the kinematics (i.e., Galactic position and velocity) and
the Galactic component membership probabilities for the stars and then
classify them into different Galactic components.
