Galactic Open Clusters
Ted von Hippel
The study of open clusters has a classic feel to it since the subject predates anyone alive today. Despite the age of this topic, I show via an ADS search that its relevance and im…
White Dwarfs in Open Clusters: Calibrating the Clock
T. von Hippel, D. E. Winget, W. H. Jefferys +1
We present an update of our on-going effort to improve the precision of white dwarf cosmochronology via careful analyses of white dwarf photometry in open clusters. To improve the…
The White Dwarf Luminosity Function: The Shape of Things to Come
T. von Hippel, M. Kilic, J. Munn +10
We describe a new survey for cool white dwarfs that supplements Sloan Digital Sky Survey photometry with USNO proper motions and follow-up spectroscopy. To date we have discovered…
The Initial-Final Mass Relationship: Spectroscopy of White Dwarfs in NGC 2099 (M37)
Jasonjot Singh Kalirai, Harvey B. Richer, David Reitzel +5
We present new observations of very faint white dwarfs (WDs) in the rich open star cluster NGC 2099 (M37). Following deep, wide field imaging of the cluster using CFHT, we have now…
