Robo-AO Discovery and Basic Characterization of Wide Multiple Star Systems in the Pleiades, Praesepe, and NGC 2264 Clusters
Lynne A. Hillenbrand, Celia Zhang, Reed L. Riddle +4
We identify and roughly characterize 66 candidate binary star systems in the Pleiades, Praesepe, and NGC 2264 star clusters based on robotic adaptive optics imaging data obtained u…
Luminosities and mass-loss rates of Local Group AGB stars and Red Supergiants
Martin A. T. Groenewegen, Greg C. Sloan
We aim to investigate mass loss and luminosity in a large sample of evolved stars in several Local Group galaxies with a variety of metalliticies and star-formation histories: the…

M. L. Boyer, K. B. W. McQuinn, M. A. T. Groenewegen +13
The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and showed that dust can fo…
Probing the structure of Kepler ZZ Ceti stars with full evolutionary models-based asteroseismology
Alejandra D. Romero, A. H. Córsico, B. Castanheira +8
We present an asteroseismological analysis of four ZZ Ceti stars observed with \emph{Kepler}: GD 1212, SDSS J113655.17+040952.6, KIC 11911480 and KIC 4552982, based on a grid of fu…
Destroying Aliases from the Ground and Space: Super-Nyquist ZZ Cetis in K2 Long Cadence Data
Keaton J. Bell, J. J. Hermes, Z. Vanderbosch +5
With typical periods of order 10 minutes, the pulsation signatures of ZZ Ceti variables (pulsating hydrogen-atmosphere white dwarf stars) are severely undersampled by long-cadence…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
Sensitivity to Thermonuclear Reaction Rates in Modeling the Abundance Anomalies of NGC 2419
John Dermigny, Christian Iliadis
Abundance anomalies in globular clusters provide strong evidence for multiple stellar populations within each cluster. These populations are usually interpreted as distinct generat…
WIRED for EC: New White Dwarfs with Infrared Excesses and New Classification Schemes from the Edinburgh-Cape Blue Object Survey
E. Dennihy, J. C. Clemens, John H. Debes +4
We present a simple method for identifying candidate white dwarf systems with dusty exoplanetary debris based on a single temperature blackbody model fit to the infrared excess. We…
White Dwarf Rotation as a Function of Mass and a Dichotomy of Mode Linewidths: Kepler Observations of 27 Pulsating DA White Dwarfs Through K2 Campaign 8
J. J. Hermes, B. T. Gaensicke, Steven D. Kawaler +15
We present photometry and spectroscopy for 27 pulsating hydrogen-atmosphere white dwarfs (DAVs, a.k.a. ZZ Ceti stars) observed by the Kepler space telescope up to K2 Campaign 8, an…
Multi-band photometry and spectroscopy of an all-sky sample of bright white dwarfs
R. Raddi, N. P. Gentile Fusillo, A. F. Pala +11
The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will obtain space-based uninterrupted light curves for a large sample of bright white dwarfs distributed across the e…
Timing by Stellar Pulsations as an Exoplanet Discovery Method
J. J. Hermes
The stable oscillations of pulsating stars can serve as accurate timepieces, which may be monitored for the influence of exoplanets. An external companion gravitationally tugs the…
A search for rapidly pulsating hot subdwarf stars in the GALEX survey
Emily M. Boudreaux, Brad N. Barlow, Scott W. Fleming +6
NASA's Galaxy Evolution Explorer (GALEX) provided near- and far-UV observations for approximately 77 percent of the sky over a ten-year period; however, the data reduction pipeline…
Magnetic Inflation and Stellar Mass I: Revised Parameters for the Component Stars of the Kepler Low-mass Eclipsing Binary T-Cyg1-12664
Eunkyu Han, Philip S. Muirhead, Jonathan J. Swift +6
Several low-mass eclipsing binary stars show larger than expected radii for their measured mass, metallicity and age. One proposed mechanism for this radius inflation involves inhi…
The Factory and the Beehive III: PTFEB132.707+19.810, a Low-Mass Eclipsing Binary in Praesepe Observed by PTF and K2
Adam L. Kraus, Stephanie T. Douglas, Andrew W. Mann +10
Theoretical models of stars constitute a fundamental bedrock upon which much of astrophysics is built, but large swaths of model parameter space remain uncalibrated by observations…
Two white dwarfs in ultrashort binaries with detached, eclipsing, likely substellar companions detected by K2
S. G. Parsons, J. J. Hermes, T. R. Marsh +19
Using data from the extended Kepler mission in K2 Campaign 10 we identify two eclipsing binaries containing white dwarfs with cool companions that have extremely short orbital peri…
