Trumpler 20 - an old and rich open cluster
I. Platais, C. Melo, J. P. Fulbright +4
We show that the open cluster Trumpler 20, contrary to the earlier findings, is actually an old Galactic open cluster. New CCD photometry and high-resolution spectroscopy are used…
Ground-based CCD astrometry with wide field imagers. II. A star catalogue for M67: [email protected] MPG/ESO astrometry, FLAMES@VLT radial velocities
R. K. S. Yadav, L. R. Bedin, G. Piotto +7
The solar-age open cluster M67 (C0847+120, NGC2682) is a touchstone in studies of the old Galactic disk. Despite its outstanding role, the census of cluster membership for M67 at f…
WIYN Open Cluster Study. XXVI. Improved kinematic membership and spectroscopy of IC 2391
I. Platais, C. Melo, J. -C. Mermilliod +5
[Abridged] Contex. Young open clusters provide important clues to the interface between the main sequence and pre-main-sequence phases of stellar evolution. The young and nearby op…
Deep Astrometric Standards (DAS) and Galactic Structure
I. Platais, R. F. G. Wyse, N. Zacharias
The advent of next-generation imaging telescopes such as LSST and Pan-STARRS has revitalized the need for deep and precise reference frames. The proposed weak-lensing observations…
The Southern Proper Motion Program III. A Near-Complete Catalog to V=17.5
T. M. Girard, D. I. Dinescu, W. F. van Altena +3
We present the third installment of the Yale/San Juan Southern Proper Motion Catalog, SPM3. Absolute proper motions, positions, and photographic B,V photometry are given for roughl…
WIYN Open Cluster Study. XVII. Astrometry and Membership to V=21 in NGC 188
I. Platais, V. Kozhurina-Platais, R. D. Mathieu +2
We present techniques for obtaining presision astrometry using old photographic plates from assorted large-aperture reflectors in combination with recent CCD Mosaic Imager frames.…
