Tautenburg proper motion fields
Astronomische Nachrichten, 1991AbstractThere 70 3° × 3± fields each with at least 4 plates taken with the Tautenburg Schmidt telescope between 1960 and 1970 which can be used as first epoch plates in the determination of proper motions. In the Tautenburg programme of obtaining absolute proper motions of HIPPARCOS stars 10 preliminary fields are included.

Globular Cluster Proper Motions
1997Although proper motion measurements provide two components of the space velocity, the third one being given by radial velocity measurements, the proper motions of stars in globular clusters have not yet been intensively used in the studies of the internal dynamics of these stellar systems.

We report the detection of proper motions in [Fe ii] 1.644 µm emission among the southeasternmost features in the Herbig-Haro object complex GGD 37. Imaging observations were made over a period of 5 yr, at epochs 1993.67, 1996.71, and 1998.68, that reveal proper-motion velocities of 400+/-200 km s-1 at GGD 37:W2 and 850+/-200 km s-1 at a newly ...
