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…
A Census of Above-Horizontal-Branch Stars in Galactic Globular Clusters
Brian D. Davis, Howard E. Bond, Michael H. Siegel +1
We have carried out a search for above-horizontal-branch (AHB) stars--objects lying above the horizontal branch (HB) and blueward of the asymptotic giant branch (AGB) in the color-…
Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE I. Methodology and Tests
Martin M. Roth, George H. Jacoby, Robin Ciardullo +3
The [O III ] 5007 Planetary Nebula Luminosity Function (PNLF) is an established distance indicator that has been used for more than 30 years to measure the distances of galaxies ou…
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…
