Estimating Complex Densities using Two-Stage Normalizing Flows
Roxana Darvishi, David C. Stenning, Ted von Hippel +1
In many scientific applications, the target probability distribution cannot be evaluated in closed form or sampled from directly. Instead, it can often be decomposed into multiple…
Composition of planetary debris around the white dwarf GD 362
William T. Reach, Mukremin Kilic, Carey M. Lisse +9
White dwarf stars with high abundances of heavy elements in their atmospheres and infrared excesses are believed to be accreting planetary material. GD 362 is one of the most heavi…
Precise Ages of Field Stars From White Dwarf Companions in Gaia DR2
Dan Qiu, Hai-Jun Tian, Xi-Dong Wang +5
We analyze 4\,050 wide binary star systems involving a white dwarf (WD) and usually a main sequence (MS) star, drawn from the large sample assembled by \citet[][hereafter, T20]{Tia…
Bayesian Characterization of Main Sequence Binaries in the Old Open Cluster NGC 188
Roger E. Cohen, Aaron M. Geller, Ted von Hippel
The binary fractions of open and globular clusters yield powerful constraints on their dynamical state and evolutionary history. We apply publicly available Bayesian analysis code…
Dust Production and Depletion in Evolved Planetary Systems
J. Farihi, R. van Lieshout, P. W. Cauley +15
The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
Bayesian Hierarchical Modelling of Initial-Final Mass Relations Across Star Clusters
Shijing Si, Ted von Hippel, Elliot Robinson +3
The initial-final mass relation (IFMR) of white dwarfs (WDs) plays an important role in stellar evolution. To derive precise estimates of IFMRs and explore how they may vary among…
