Variable stars in the globular cluster NGC 3201. I. Multimode SX Phe-type variables
We report on the discovery of eleven multimode SX Phoenicis–type blue stragglers in the field of the southern globular cluster NGC 3201. In these variables both radial and non-radial modes are excited. For three variables the derived period ratio is close to that observed in SX Phoenicis itself, suggesting that these stars are pulsating in the fundamental and the first-overtone radial modes. Us...
متن کاملTelescope Study of the Globular Cluster Ngc 288
We report on the Chandra X-ray Observatory observations of the globular cluster NGC 288. We detect four X-ray sources within the core radius and seven additional sources within the half-mass radius down to a limiting luminosity of LX = 7×1030 ergs s−1 (assuming cluster membership) in the 0.3–7 keV band. We also observed the cluster with the Hubble Space Telescope Advanced Camera for Surveys and...
متن کاملCluster AgeS Experiment ( CASE ) : SX Phe stars from the globular cluster ω
We present an analysis and interpretation of oscillation spectra for all 69 SX Phoenicis stars discovered in the field of the cluster. For most of the stars we have reliable absolute magnitudes and colors. Except of one, or perhaps two, objects, the stars are cluster members. Their pulsational behaviour is very diversified. Multiperi-odic variability with at least part of the excited modes bein...
متن کاملGlobular Cluster Metallicity Subpopulations in NGC 4472
Bimodality is a common feature of globular cluster (GC) color distributions in galaxies. Although it is well known that the GC system of the Milky Way is bimodal in metallicity, this has yet to be directly demonstrated for an elliptical galaxy. We use Lick index measurements from the literature to derive metallicities for 47 GCs in the giant Virgo elliptical galaxy NGC 4472. The resulting distr...
متن کاملCcd Observations of the Rr Lyrae Variables in the Globular Cluster Ngc 5897
CCD observations for 10 (6 previously known and 4 newly discovered) of the 11 RR Lyrae variables in NGC 5897 have been analysed. The period-luminosity and period-amplitude plots indicate that the population of RR Lyrae variables in NGC 5897 includes 3 fundamental mode, 4 first-overtone and 4 second-overtone variables with mean periods 0.828, 0.459 and 0.343 respectively. The variables have prop...
