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…
Two Luminous Post-AGB Stars in the Galactic Globular Cluster M19
Howard E. Bond, Brian D. Davis, Michael H. Siegel +1
We report the discovery of a luminous "yellow" post-asymptotic-giant-branch (PAGB) star in the globular cluster (GC) M19 (NGC 6273), identified during our uBVI survey of Galactic G…
Hubble Space Telescope Spectroscopy of a Planetary Nebula in an M31 Open Cluster: Hot-Bottom Burning at
Brian D. Davis, Howard E. Bond, Robin Ciardullo +1
We use imaging and spectroscopy from the Hubble Space Telescope (HST) to examine the properties of a bright planetary nebula (PN) projected within M31's young open cluster B477-D07…
The Recurrent Nova Candidate M31N 1966-08a = 1968-10c is a Galactic Flare Star
A. W. Shafter, M. Henze, M. J. Darnley +3
A spectrum of the quiescent counterpart of the Recurrent Nova candidate M31N 1966-08a (= M31N 1968-10c) obtained with LRS2 on the Hobby-Eberly Telescope reveals the object to be a…
