An Overview of the Rotational Behavior of Metal--Poor Stars
C. Cortés, J. R. P. Silva, A. Recio-Blanco +3
The present paper describes the behavior of the rotational velocity in metal--poor stars ([Fe/H]<-0.5 dex) in different evolutionary stages, based on Vsini values from the literatu…
Time-Series Photometry of Globular Clusters: M62 (NGC 6266), the Most RR Lyrae-Rich Globular Cluster in the Galaxy?
R. Contreras, M. Catelan, H. A. Smith +3
We present new time-series CCD photometry, in the B and V bands, for the moderately metal-rich ([Fe/H] ~ -1.3) Galactic globular cluster (GC) M62 (NGC 6266). The present dataset is…
A search for dormant binaries with degenerate components in omega Centauri and NGC 6397
M. Rozyczka, J. Kaluzny, P. Pietrukowicz +4
We report on the first spectroscopic search for quiescent degenerate binaries in globular clusters. Our survey is based on a sample of short-period optical variables which are like…
