Cluster Study . Xxiv . Stellar Radial - Velocity Measurements in Ngc 6819
We present the current results from our ongoing radial-velocity survey of the intermediate-age (2.4 Gyr) open cluster NGC 6819. Using both newly observed and other available photometry and astrometry we define a primary target sample of 1454 stars that includes main-sequence, subgiant, giant, and blue straggler stars, spanning a magnitude range of 11≤V≤16.5 and an approximate mass range of 1.1 ...

متن کاملWiyn Open Cluster Study: Stellar Radial Velocities with the Wiyn 3.5m Telescope 2. the Telescope and Instrument
As part of the WIYN Open Cluster Study (WOCS), we have used the WIYN 3.5m telescope and Hydra multiobject spectrograph since 1996 to obtain precise radial velocities of a large number of stars in the four open clusters currently under investigation. In order of increasing age, these are NGC 2264, NGC 2168, NGC 6819, and NGC 188. Currently the largest dataset (5000 observations) is that for NGC ...
متن کاملWIYN Open Cluster Study. XVII. Astrometry and Membership to V = 21 in NGC 188.
We present techniques for obtaining precision astrometry using old photographic plates from assorted large-aperture reflectors in combination with recent CCD Mosaic Imager frames. At the core of this approach is a transformation of plate/CCD coordinates into a previously constructed astrometric reference frame around the open cluster NGC 188. This allows us to calibrate independently the Optica...
متن کاملWIYN Open Cluster Study: Tidal Interactions in Solar type Binaries
We present an ongoing study on tidal interactions in late-type close binary stars. New results on tidal circularization are combined with existing data to test and constrain theoretical predictions of tidal circularization in the premain-sequence (PMS) phase and throughout the main-sequence phase of stellar evolution. Current data suggest that tidal circularization during the PMS phase sets the...
