Ground-Based Astrometry 2010-2020
Todd J. Henry, David G. Monet, Paul D. Shankland +3
We discuss the opportunities for astronomical discovery via ground-based astrometry carried out in the United States during the 2010-2020 decade. We describe imminent scientific br…
Common Proper Motion Companions to Nearby Stars: Ages and Evolution
V. V. Makarov, N. Zacharias, G. S. Hennessy
A set of 41 nearby stars (closer than 25 pc) is investigated which have very wide binary and common proper motion (CPM) companions at projected separations between 1000 and $200 00…
The StarScan plate measuring machine: overview and calibrations
Norbert Zacharias, Lars Winter, Ellis Holdenried +3
The StarScan machine at the U.S. Naval Observatory (USNO) completed measuring photographic astrograph plates to allow determination of proper motions for the USNO CCD Astrograph Ca…
Realization and application of a 111 million pixel backside-illuminated detector and camera
Norbert Zacharias, Bryan Dorland, Richard Bredthauer +3
A full-wafer, 10,580 10,560 pixel (95 95 mm) CCD was designed and tested at Semiconductor Technology Associates (STA) with 9 um square pixels and 16 outputs. The…
The nearby young visual binary HIP 115147 and its common proper motion companion LSPM J2322+7847
V. V. Makarov, N. Zacharias, G. S. Hennessy +2
We report a late M-type, common proper motion companion to a nearby young visual binary HIP 115147 (V368 Cep), separated by 963 arcseconds from the primary K0 dwarf. This optically…
VLA+PT Astrometry of 46 Radio Stars
D. A. Boboltz, A. L. Fey, W. K. Puatua +4
We have used the Very Large Array (VLA), linked with the Pie Town Very Long Baseline Array antenna, to determine astrometric positions of 46 radio stars in the International Celest…
