Ionized Nebulae Around Two New Symbiotic Stars: GR Cygni and [D75] 141
Howard E. Bond, Calvin Carter, Sven E. Eklund +4
In the course of selecting targets for a spectroscopic survey of faint planetary-nebula nuclei, we encountered two anomalous cases of late-type variable stars surrounded by nebulos…
A Bow-Shock Nebula Around the Z Camelopardalis-type Cataclysmic Variable FY Vulpeculae
Howard E. Bond, Calvin Carter, Eric Coles +3
We present deep images of the faint nebulosity StDr 90, which we have discovered surrounds the cataclysmic variable (CV) star FY Vulpeculae. Archival photometric and spectroscopic…
Two More Bow Shocks and Off-Center Halpha Nebulae Associated with Nova-like Cataclysmic Variables
Howard E. Bond, Calvin Carter, Eric Coles +4
We report discoveries of bow-shock nebulae, seen in Halpha and [O III] 5007, around two cataclysmic variables (CVs): LS Pegasi and ASASSN-V J205457.73+515731.9 (hereafter ASASJ2054…
Discovery of a Bow-Shock Nebula around the Z Cam-type Cataclysmic Variable SY Cancri
Howard E. Bond, Calvin Carter, David F. Elmore +3
We report the serendipitous discovery of a bow-shock nebula around the cataclysmic variable (CV) SY Cancri. In addition, SY Cnc lies near the edge of a faint Halpha-emitting nebula…
