George Jacoby, John Feldmeier, Charles F. Claver +4
SBS 1150+599A is a blue stellar object at high galactic latitude discovered in the Second Byurakan Survey. New high-resolution images of SBS 1150+599A are presented, demonstrating…
FIRST J102347.6+003841: The First Radio-Selected Cataclysmic Variable
Howard E. Bond, Richard L. White, Robert H. Becker +1
We have identified the 1.4 GHz radio source FIRST J102347.6+003841 (hereafter FIRST J1023+0038) with a previously unknown 17th-mag Galactic cataclysmic variable (CV). The optical s…
Hubble Space Telescope Expansion Parallaxes of the Planetary Nebulae NGC 6578, NGC 6884, NGC 6891, and IC 2448
Stacy Palen, Bruce Balick, Arsen R. Hajian +3
We have combined two epochs of Hubble Space Telescope WFPC2 imaging data with ground-based expansion velocities to determine distances to three planetary nebulae (NGC 6578, NGC 688…
