Spectroscopic survey of faint planetary-nebula nuclei. II. The subdwarf O central star of Fr 2-30
Howard E. Bond, Klaus Werner, Gregory R. Zeimann +1
Fr 2-30 = PN? G126.8-15.5 is a faint emission nebula, hosting a 14th-mag central star that we identify here for the first time. Deep Halpha and [O III] images reveal a roughly elli…
Spectroscopic survey of faint planetary-nebula nuclei. I. Six new "O VI" central stars
Howard E. Bond, Klaus Werner, George H. Jacoby +1
We report initial results from an ongoing spectroscopic survey of central stars of faint planetary nebulae (PNe), obtained with the Low-Resolution Spectrograph on the Hobby-Eberly…
Nova Sagittarii 1943 (V1148 Sgr): A Luminous Red Nova?
Howard E. Bond, Jessica Mink, Allison Doane +1
Nova Sagittarii 1943 (V1148 Sgr) was an 8th-mag optical transient that was unusual in having a late-type spectrum during its outburst, in striking contrast to the normal high-excit…
Spectroscopic Confirmation of Two Luminous Post-AGB Stars in the Globular Cluster M19
Howard E. Bond, Jacob E. Jencson, Robin Ciardullo +2
The visually brightest stars in globular clusters (GCs) are the ones evolving off the asymptotic giant branch (AGB) and passing through spectral types F and A--the "yellow" post-AG…
Yellow Post-Asymptotic-Giant-Branch Stars as Standard Candles. I. Calibration of the Luminosity Function in Galactic Globular Clusters
Robin Ciardullo, Howard E. Bond, Brian D. Davis +1
We use results of a survey for low-surface-gravity stars in Galactic (and LMC) globular clusters to show that "yellow" post-asymptotic-giant-branch (yPAGB) stars are likely to be e…
Hubble Space Telescope Imaging of Luminous Extragalactic Infrared Transients and Variables from the SPIRITS Survey
Howard E. Bond, Jacob E. Jencson, Patricia A. Whitelock +6
SPIRITS--the SPitzer InfraRed Intensive Transients Survey--searched for luminous infrared (IR) transients and variables in nearly 200 nearby galaxies from 2014 to 2019, using the w…
