Binary Systems Search with TESS
Tomomi Otani, A. S. Baran, Lindsay C. Spence +3
Hot subdwarf B (sdB) stars are post-main-sequence stars of high temperature and gravity. Approximately 30 of sdBs exhibit stable pressure and/or gravity-mode pulsations, which…
Near-infrared variability in dusty white dwarfs: tracing the accretion of planetary material
Laura K. Rogers, Siyi Xu, Amy Bonsor +4
The inwards scattering of planetesimals towards white dwarfs is expected to be a stochastic process with variability on human time-scales. The planetesimals tidally disrupt at the…
The ACS Survey of Galactic Globular Clusters XIV: Bayesian Single-Population Analysis of 69 Globular Clusters
R. Wagner-Kaiser, A. Sarajedini, T. von Hippel +7
We use Hubble Space Telescope (HST) imaging from the ACS Treasury Survey to determine fits for single population isochrones of 69 Galactic globular clusters. Using robust Bayesian…
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…
Constraining the Surface Inhomogeneity and Settling Times of Metals on Accreting White Dwarfs
M. H. Montgomery, S. E. Thompson, T. von Hippel
Due to the short settling times of metals in DA white dwarf atmospheres, any white dwarfs with photospheric metals must be actively accreting. It is therefore natural to expect tha…
