Robust high-contrast companion detection from interferometric observations. The CANDID algorithm and an application to six binary Cepheids
A. Gallenne, A. Mérand, P. Kervella +15
Long-baseline interferometry is an important technique to spatially resolve binary or multiple systems in close orbits. By combining several telescopes together and spectrally disp…
Estimation of distances to stars with stellar parameters from LAMOST
Jeffrey L. Carlin, Chao Liu, Heidi Jo Newberg +15
We present a method to estimate distances to stars with spectroscopically derived stellar parameters. The technique is a Bayesian approach with likelihood estimated via comparison…
The Expanding Fireball of Nova Delphini 2013
G. H. Schaefer, T. ten Brummelaar, D. R. Gies +34
A classical nova occurs when material accreting onto the surface of a white dwarf in a close binary system ignites in a thermonuclear runaway. Complex structures observed in the ej…
Physical Properties of the Current Census of Northern White Dwarfs within 40 pc of the Sun
M. -M. Limoges, P. Bergeron, S. Lépine
We present a detailed description of the physical properties of our current census of white dwarfs within 40 pc of the Sun, based on an exhaustive spectroscopic survey of northern…
HST/COS Detection of the Spectrum of the Subdwarf Companion of KOI-81
Rachel A. Matson, Douglas R. Gies, Zhao Guo +5
KOI-81 is a totally eclipsing binary discovered by the Kepler mission that consists of a rapidly rotating B-type star and a small, hot companion. The system was forged through larg…
Detecting the Companions and Ellipsoidal Variations of RS CVn Primaries: I. sigma Geminorum
Rachael M. Roettenbacher, John D. Monnier, Gregory W. Henry +17
To measure the properties of both components of the RS CVn binary sigma Geminorum (sigma Gem), we directly detect the faint companion, measure the orbit, obtain model-independent m…
