J/MNRAS/414/3711     Proper motion study of M55 stars        (Zloczewski+, 2011)

A proper motion study of the globular cluster M55. Zloczewski K., Kaluzny J., Thompson I.B. <Mon. Not. R. Astron. Soc., 414, 3711-3718 (2011)> =2011MNRAS.414.3711Z
ADC_Keywords: Clusters, globular ; Proper motions Keywords: astrometry - binaries: eclipsing - blue stragglers - globular clusters: individual: NGC 6809 (M55) - galaxies: individual: Sagitarrius dSph Abstract: We have derived the absolute proper motion (PM) of the globular cluster M55 using a large set of CCD images collected with the du Pont telescope between 1997 and 2008. We find (pmRAcosDE, pmDE)=(-3.31±0.10, -9.14±0.15)mas/yr relative to background galaxies. Membership status was determined for 16945 stars with 14<V<21 from the central part of the cluster. Description: The images of M55 analysed in this paper were selected from the data collected by the Cluster AgeS Experiment (CASE) project during the period 1997-2008. Observations were made with the 2.5-m du Pont telescope at Las Campanas Observatory. All images were obtained with the same detector and the same set of filters. File Summary:
