Photometric survey of marginally investigated open clusters : I . Basel 11 b , King 14 , Czernik 43 ⋆
To progress in galactic studies based on open clusters, e.g. cluster formation rate or kinematical properties, one needs to improve the number of open clusters observed. However, only half of the 1700 known galactic open clusters have been properly observed so far, making any statistical investigation insignificant, especially at larger distances from the Sun. We study marginally investigated o...
متن کاملPhotometric Monitoring of Open Clusters I. The Survey
Open clusters, which have age, abundance, and extinction information from studies of main-sequence turn off stars, are the ideal location in which to determine the mass-luminosity-radius relation for low-mass stars. We have undertaken a photometric monitoring survey of open clusters in the Galaxy designed to detect low-mass eclipsing binary systems through variations in their relative light cur...
متن کاملBoao Photometric Survey of Galactic Open Clusters. I.
Open clusters are useful tools to investigate the structure and evolution of the Galactic disk. We have started a long-term project to obtain UBV I CCD photometry of open clusters which were little studied before, using the Doyak 1.8 m telescope of Bohyunsan Optical Astronomy Observatory in Korea. The primary goals of this project are (1) to make a catalog of UBV I photometry of open clusters, ...
متن کامل2 BOAO PHOTOMETRIC SURVEY OF GALACTIC OPEN CLUSTERS . II . Physical Parameters of 12 Open Clusters
Received ; accepted – 2 – ABSTRACT We have initiated a long-term project, the BOAO photometric survey of open clusters, to enlarge our understanding of galactic structure using UBV I CCD photometry of open clusters which have been little studied before. This is the second paper of the project in which we present the photometry of 12 open clusters. We have determined the cluster parameters by fi...
متن کاملPhotometric and kinematic studies of open star clusters
We present CCD photometry and proper motion studies of the two open star clusters NGC 1960 (M 36) and NGC 2194. Fitting isochrones to the colour magnitude diagrams, for NGC 1960 we found an age of t = 16Myr and a distance of roughly d = 1300 pc and for NGC 2194 t = 550Myr and d = 2900 pc, respectively. We combined membership determination by proper motions and statistical field star subtraction...
