The pulsating white dwarf G117-B15A: still the most stable optical clock known
S. O. Kepler, D. E. Winget, Zachary P. Vanderbosch +14
The pulsating hydrogen atmosphere white dwarf star G 117-B15A has been observed since 1974. Its main pulsation period at 215.19738823(63) s, observed in optical light curves, varie…
The Ages of the Thin Disk, Thick Disk, and the Halo from Nearby White Dwarfs
Mukremin Kilic, Jeffrey A. Munn, Hugh C. Harris +5
We present a detailed analysis of the white dwarf luminosity functions derived from the local 40 pc sample and the deep proper motion catalog of Munn et al (2014, 2017). Many of th…
A Deep Proper Motion Catalog Within the Sloan Digital Sky Survey Footprint. II. The White Dwarf Luminosity Function
Jeffrey A. Munn, Hugh C. Harris, Ted von Hippel +8
A catalog of 8472 white dwarf (WD) candidates is presented, selected using reduced proper motions from the deep proper motion catalog of Munn et al. 2014. Candidates are selected i…
Bayesian Analysis for Stellar Evolution with Nine Parameters (BASE-9): User's Manual
Ted von Hippel, Elliot Robinson, Elizabeth Jeffery +6
BASE-9 is a Bayesian software suite that recovers star cluster and stellar parameters from photometry. BASE-9 is useful for analyzing single-age, single-metallicity star clusters,…
The White Dwarf Age of NGC 2477
Elizabeth J. Jeffery, Ted von Hippel, Steven DeGennaro +3
We present deep photometric observations of the open cluster NGC 2477 using HST/WFPC2. By identifying seven cluster white dwarf candidates, we present an analysis of the white dwar…
Visitors from the Halo: 11 Gyr old White Dwarfs in the Solar Neighborhood
Mukremin Kilic, Jeffrey A. Munn, Kurtis A. Williams +7
We report the discovery of three nearby old halo white dwarf candidates in the Sloan Digital Sky Survey (SDSS), including two stars in a common proper motion binary system. These c…
