Oxygen abundance of open cluster dwarfs
Z. -X. Shen, X. -W. Liu, H. -W. Zhang +2
We present oxygen abundances of dwarfs in the young open cluster IC 4665 deduced from the OI 7774 triplet lines and of dwarfs in the open cluster Pleiades derived from the [OI]…
Confirmation of Errors in Hipparcos Parallaxes from HST/FGS Astrometry of the Pleiades
David R. Soderblom, Ed Nelan, G. Fritz Benedict +4
We present absolute trigonometric parallaxes and relative proper motions for three members of the Pleiades star cluster, obtained with HST's Fine Guidance Sensor 1r, a white-light…
Lick Northern Proper Motion Program. III. Lick NPM2 Catalog
Robert B. Hanson, Arnold R. Klemola, Burton F. Jones +1
The Lick Northern Proper Motion (NPM) program, a two-epoch (1947-1988) photographic survey of the northern two-thirds of the sky (Dec. > -23 deg), has measured absolute proper moti…
Chandra X-ray observations of Young Clusters II. Orion Flanking Fields Data
Solange V. Ramirez, Luisa Rebull, John Stauffer +7
We present results of Chandra observations of two flanking fields (FF) in Orion, outside the Orion Nebula Cluster (ONC). The observations were taken with the ACIS-I camera with an…
Chandra X-ray observations of Young Clusters I. NGC2264 Data
Solange V. Ramirez, Luisa Rebull, John Stauffer +7
We present results of a Chandra observation of a field in NGC 2264. The observations were taken with the ACIS-I camera with an exposure time of 48.1 ks. We present a catalog of 263…
Why are the K dwarfs in the Pleiades so Blue?
John R. Stauffer, Burton F. Jones, Dana Backman +5
The K dwarfs in the Pleiades fall nearly one half magnitude below a main sequence isochrone when plotted in a color-magnitude diagram utilizing V magnitude as the luminosity index…
