Abstract:
The LAMOST-Kepler (LK-) project was initiated to use the Large Sky
Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) to make
spectroscopic follow-up observations for the targets in the field of
the Kepler mission. The Kepler field is divided into 14 subfields that
are adapted to the LAMOST circular field with a diameter of 5°.
During the regular survey phase of LAMOST, the LK-project took data
from 2012 June to 2017 June and covered all 14 subfields at least
twice. In particular, we describe in this paper the second Data
Release of the LK-project, including all spectra acquired through
2015-May--2017-June together with the first round observations of the
LK-project from 2012 June to 2014 September. The LK-project now counts
227,870 spectra of 156,390 stars, among which we have derived
atmospheric parameters (logg, Teff, and [Fe/H]) and heliocentric
radial velocity for 173,971 spectra of 126,172 stars. These parameters
were obtained with the most recent version of the LAMOST Stellar
Parameter Pipeline v 2.9.7. Nearly one half, namely 76,283 targets,
are observed both by the LAMOST and Kepler telescopes. These spectra,
establishing a large spectroscopy library, will be useful for the
entire astronomical community, particularly for planetary science and
stellar variability on Kepler targets.
Description:
The details of the observations of the first round of the
LAMOST-Kepler (LK-) project from 2012 to 2014 are given in Paper I
(De Cat+ 2015, J/ApJS/220/19).
Here, we focus on the second round of observations of the LK-project,
which began on 2015 May 29 and ended on 2017 June 15. A total of 48
plates were observed on 24 observation nights: 32 plates on 18 nights
in 2015 and 16 plates on 6 nights 2017.
