The Search for Multiple Populations in Magellanic Cloud Clusters I: Two Stellar Populations in the Small Magellanic Cloud Globular Cluster NGC 121
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
We started a photometric survey using the WFC3/UVIS instrument onboard the Hubble Space Telescope to search for multiple populations within Magellanic Cloud star clusters at variou…
BVRIJHK photometry and proper motion analysis of NGC 6253 and the surrounding field
M. Montalto, G. Piotto, S. Desidera +5
Context. We present a photometric and astrometric catalog of 187963 stars located in the field around the old super-metal-rich Galactic open cluster NGC 6253. The total field-of-vi…
Ground-based CCD astrometry with wide field imagers. III. [email protected] proper-motion catalog of the globular cluster omega Centauri
A. Bellini, G. Piotto, L. R. Bedin +6
Omega Centauri is the most well studied Globular Cluster because of its numerous puzzling features. Intensive spectroscopic follow-up observing campaigns targeting stars at differe…
Discovery of seven T Tauri stars and a brown dwarf candidate in the nearby TW Hydrae Association
R. A. Webb, B. Zuckerman, I. Platais +4
We report the discovery of five T Tauri star systems, two of which are resolved binaries, in the vicinity of the nearest known region of recent star formation, the TW Hydrae Associ…
The Distance to the Hyades Cluster Based on HST Fine Guidance Sensor Parallaxes
W. F. van Altena
Trigonometric parallax observations made with the Hubble Space Telescope's Fine Guidance Sensor #3 (HST FGS) of seven Hyades Cluster members in six fields of view have been analyze…
