Some Subdwarf Models

, 1962
In this paper we present the results obtained from the numerical integration of the equations for the case of subdwarfs with masses comparable and somewhat larger than that of the Sun.

High Proper Motion Discoveries from the UKIRT Hemisphere Survey

The Astronomical Journal
We used the third data release of the UKIRT Hemisphere Survey to locate previously unrecognized high proper motion objects. We identify a total of 127 new discoveries with total proper motions ≳300 mas yr ^−1 .
