Study of Globular Cluster M53: new variables, distance, metallicity (2009)
We study the variable star content of the globular cluster M53 to compute the physical parameters of the constituting stars and the distance of the cluster. Covering two adjacent seasons in 2007 and...
Physical properties of double-mode RR Lyrae stars based on pulsation and evolution models (2009)
We determine the fundamental stellar parameters of altogether 20 double-mode RR Lyrae (RRd) stars from the Galactic Field and the Large Magellanic Cloud, following our approach employed on the field...
