Description
The nearly continuous light curves with micromagnitude precision
provided by the space mission Kepler are revolutionizing our view of
pulsating stars. They have revealed a vast sea of low-amplitude
pulsation modes that were undetectable from Earth. The long time base of
Kepler light curves allows for the accurate determination of the
frequencies and amplitudes of pulsation modes needed for in-depth
asteroseismic modeling. However, for an asteroseismic study to be
successful, the first estimates of stellar parameters need to be known
and they cannot be derived from the Kepler photometry itself. The Kepler
Input Catalog provides values for the effective temperature, surface
gravity, and metallicity, but not always with sufficient accuracy.
Moreover, information on the chemical composition and rotation rate is
lacking. We are collecting low-resolution spectra for objects in the
Kepler field of view with the Large Sky Area Multi-Object Fiber
Spectroscopic Telescope (lamost, Xinglong observatory, China). All of
the requested fields have now been observed at least once. In this
paper, we describe those observations and provide a useful database for
the whole astronomical community.
