Polaris: astrometric orbit, position, and proper motion
We derive the astrometric orbit of the photo-center of the close pair α UMi AP (= α UMi Aa) of the Polaris multiple stellar system. The orbit is based on the spectroscopic orbit of the Cepheid α UMi A (orbital period of AP: 29.59 years), and on the difference ∆μ between the quasi-instantaneously measured HIPPARCOS proper motion of Polaris and the longterm-averaged proper motion given by the FK5...
متن کاملOGLE-II High Proper Motion Stars towards the Galactic centre
The photometry data base of the second phase of the OGLE microlensing experiment, OGLE-II, is a rich source of information about the kinematics and structure of the Galaxy. In this work we use the OGLE-II proper motion catalogue to identify candidate stars which have high proper motions. 521 stars with proper motion μ > 50 mas yr in the OGLE-II proper motion catalogue (Sumi et al. 2004) were cr...
متن کاملHigh Proper Motion Objects from the UKIDSS Galactic Plane Survey
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a 7 year effort to survey ∼1800 deg of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K band data, with a baseline of 2 to 8 years, for the purpose of investigating variability and measuring proper motions. We have calculated proper motions for 167 Million sources in a 900 deg area located a...
متن کاملQSOs from the variability and proper motion survey in the M3 field
We present results of the spectroscopical follow-up observations of QSO candidates from a combined variability and proper motion (VPM) survey in a ∼ 10 square degrees region centered on the globular cluster M3. The search is based on a large number of digitised Schmidt plates with a time-baseline of three decades. This paper reviews the candidate selection, the follow-up spectroscopy, and gener...
متن کاملProper Motion Dispersions of Red Clump Giants in the Galactic Bulge: Observations and Model Comparisons
Red clump giants in the Galactic bulge are approximate standard candles and hence they can be used as distance indicators. We compute the proper motion dispersions of RCG stars in the Galactic bulge using the proper motion catalogue from the second phase of the Optical Gravitational Microlensing Experiment (OGLE-II, Sumi et al. 2004) for 45 fields. The proper motion dispersions are measured to ...
