Spectroscopic Study of Kepler Asteroseismic Targets

Frasca, A.; Latham, D. W.; Jerzykiewicz, M. +1 more

Reported are spectroscopic observations of 15 candidates for Kepler primary asteroseismic targets and 14 other stars in the Kepler field, carried out at three observatories. For all these stars, the radial velocities, effective temperature, surface gravity, metallicity, and the projected rotational velocity are derived from two separate sets of da…
