Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
PG 2131+066: A Test of Pre-White Dwarf Asteroseismology
M. Reed, Steven D. Kawaler, M. Sean O'Brien
PG 2131+066 is a composite-spectrum binary with a hot pulsating PG 1159-type pre-white dwarf and an early M-type main sequence star. Analysis of Whole Earth Telescope observations…
Approaching the Gamow window with stored ions: Direct measurement of Xe(p,) in the ESR storage ring
J. Glorius, C. Langer, Z. Slavkovská +63
We report the first measurement of low-energy proton-capture cross sections of Xe in a heavy ion storage ring. Xe ions of five different beam energies betwe…
2006 Whole Earth Telescope Observations of GD358: A New Look at the Prototype DBV
J. L. Provencal, M. H. Montgomery, A. Kanaan +53
We report on the analysis of 436.1 hrs of nearly continuous high-speed photometry on the pulsating DB white dwarf GD358 acquired with the Whole Earth Telescope (WET) during the 200…
A portable and high intensity 24 keV neutron source based on Sb-Be photoneutrons and an iron filter
A. Biekert, C. Chang, L. Chaplinsky +27
A portable monoenergetic 24 keV neutron source based on the Sb-Be photoneutron reaction and an iron filter has been constructed and characterized. The coincidence of th…
The sdB pulsating star V391 Peg and its putative giant planet revisited after 13 years of time-series photometric data
R. Silvotti, S. Schuh, S. -L. Kim +10
V391 Peg (alias HS2201+2610) is a subdwarf B (sdB) pulsating star that shows both p- and g-modes. By studying the arrival times of the p-mode maxima and minima through the O-C meth…
