Metal-Rich SX Phe stars in the Kepler Field
James M. Nemec, Luis A. Balona, Simon J. Murphy +2
A spectroscopic and photometric analysis has been carried out for thirty-two candidate SX_Phe variable blue straggler stars in the Kepler-field (Balona & Nemec 2012). Radial veloci…
The hot Gamma-Doradus and Maia stars
L. A. Balona, C. A. Engelbrecht, Yogesh C. Joshi +8
The hot ~Doradus stars have multiple low frequencies characteristic of ~Dor or SPB variables, but are located between the red edge of the SPB and the blue edge of the ~Dor…
Differential rotation in K, G, F and A stars
Luis A. Balona, Oyirwoth P. Abedigamba
Rotational light modulation in Kepler photometry of K - A stars is used to estimate the absolute rotational shear. The rotation frequency spread in 2562 carefully selected stars wi…
