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…
Search for L4 Earth Trojan asteroids with the 2.5-meter Wide Field Survey Telescope
Junqiang Lu, Lulu Fan, Shaohan Wang +16
Earth Trojan asteroids (ETAs) are a mysterious population, and dynamically stable ETAs, if primordial, could be "living fossils" of the early solar system. To date, there are only…
Spectroscopic Survey of Faint Planetary-Nebula Nuclei. VIII. The Dwarf Barium Central Star of Kohoutek 1-9
Howard E. Bond, Peter Goodhew, Daniel Stern +2
In the course of our ongoing survey of faint planetary-nebula nuclei (PNNi), we obtained optical spectroscopy of the central star of the little-studied PN Kohoutek~1-9 (K 1-9). Its…
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…
Static Microlensing: Concept, Method and Candidates
Qi Guo, Leyao Wei, Wentao Luo +6
We propose a novel microlensing event search method that differs from either the traditional time domain method, astrometric microlensing, or the parallax microlensing method. Our…
