Discovery of a Variable Star Population in NGC 2808
We have applied the image subtraction method to images of the peculiar, bimodal-horizontal branch globular cluster NGC 2808, taken over a total of six nights over a range of five months. As a result, we have found, for the first time, a sizeable population of variable stars in the crowded inner regions of the cluster, thus raising the known RR Lyrae population in the cluster to a total of 18 st...
متن کاملThe Star Cluster population of NGC 5253 ⋆
We present a detailed analysis of the star cluster population in the starburst galaxy NGC 5253. Our work is based on HST optical and VLT Ks images. We detect more than 300 clusters, and for all of them we derive the photometry in the V, I and Ks bands and built a color-color V-I/V-Ks diagram. After correction for star contamination, we matched 115 sources in all the three bands V, I and Ks. Com...
متن کاملPhotometric study of the variable star population in the globular cluster NGC 6397
We present the results of a photometric survey for variable stars in the central region of the nearby globular cluster NGC 6397. Time series photometry was obtained for 30 variable objects. The sample includes 12 new objects, of which 6 show periodic light curves and 2 are eclipsing binaries of unknown period. Six variables possess certain and three possess likely X-ray counterparts detected wi...
متن کاملThe distance to the LMC cluster NGC 1866 ; clues from the cluster Cepheid population
Recent investigations aimed at estimating the distance to the young LMC cluster NGC 1866 have made use of Red Clump stars in the surrounding LMC field, together with empirical and theoretical Main-Sequence fitting methods, and have found significantly different distances for the field and the cluster, the latter being closer by in distance modulus by ∆(DM)∼0.20 mag. In this paper we (re-)consid...
متن کاملThe Distance of the Large Magellanic Cloud Cluster NGC 1866
Hubble Space Telescope V, I photometry of stars in the Large Magellanic Cloud cluster NGC 1866 shows a well defined cluster main sequence down to V=25 mag, with little contamination from field or foreground stars. We use the main sequence fitting procedure to link the distance of NGC 1866 to the Hipparcos determination of the distance for the Hyades MS stars, making use of evolutionary prescrip...
