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…
SX Phoenicis Stars in the Globular Cluster M 92
Kopacki, G.
We present results of a search for SX Phe stars in the globular cluster M 92. In photometric reductions, we used the image subtraction method supplemented with a procedure of searching for short-period variables, based on the examination of each pixel in the CCD frame. In addition to two SX Phe stars already known in the cluster, we have found fiv…
