Whole Earth Telescope observations of BPM 37093: a seismological test of crystallization theory in white dwarfs
A. Kanaan, A. Nitta, D. E. Winget +3
BPM 37093 is the only hydrogen-atmosphere white dwarf currently known which has sufficient mass (~ 1.1 M_sun) to theoretically crystallize while still inside the ZZ Ceti instabilit…
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…
Photometric Identification of Cool White Dwarfs
M. Kilic, D. E. Winget, Ted von Hippel +1
We investigate the use of a narrow-band DDO51 filter for photometric identification of cool white dwarfs. We report photometric observations of 30 known cool white dwarfs with temp…
Re-defining the Empirical ZZ Ceti Instability Strip
Anjum S. Mukadam, D. E. Winget, Ted von Hippel +3
We use the new ZZ Ceti stars (hydrogen atmosphere white dwarf variables; DAVs) discovered within the Sloan Digital Sky Survey (Mukadam et al. 2004) to re-define the empirical ZZ Ce…
Proper Motion Objects in the Hubble Deep Field
M. Kilic, Ted von Hippel, R. A. Mendez +1
Using the deepest and finest resolution images of the Universe acquired with the Hubble Space Telescope and a similar image taken 7 years later for the Great Observatories Origins…
