A deep test of radial differential rotation in a helium-atmosphere white dwarf: I. Discovery of pulsations in PG 0112+104
J. J. Hermes, Steven D. Kawaler, A. Bischoff-Kim +3
We present the detection of non-radial oscillations in a hot, helium-atmosphere white dwarf using 78.7 d of nearly uninterrupted photometry from the Kepler space telescope. With an…
Pruning The ELM Survey: Characterizing Candidate Low-Mass White Dwarfs Through Photometric Variability
Keaton J. Bell, A. Gianninas, J. J. Hermes +7
We assess the photometric variability of nine stars with spectroscopic Teff and log(g) values from the ELM Survey that locate them near the empirical extremely low-mass (ELM) white…
Characterizing the Population of Bright Infrared Sources in the Small Magellanic Cloud
K. E. Kraemer, G. C. Sloan, P. R. Wood +2
We used Spitzer's Infrared Spectrograph (IRS) to observe stars in the Small Magellanic Cloud (SMC) selected from the Midcourse Space Experiment (MSX) Point Source Catalog. We conce…
Towards Understanding The B[e] Phenomenon: VI. Nature and Spectral Variations of HD 85567
S. A. Khokhlov, A. S. Miroshnichenko, R. Mennickent +7
We report the results of high-resolution () spectroscopic observations of the emission-line object HD 85567, which has been classified as a FS CMa type object or a p…
Structure, Dynamics and Deuterium Fractionation of Massive Pre-Stellar Cores
Matthew D. Goodson, Shuo Kong, Jonathan C. Tan +2
High levels of deuterium fraction in NH are observed in some pre-stellar cores. Single-zone chemical models find that the timescale required to reach observed values ($D_{\…
The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag
M. J. McAllister, S. P. Littlefair, V. S. Dhillon +10
The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can significantly affect the mo…
Bayesian Estimation of Thermonuclear Reaction Rates
Christian Iliadis, Kevin Anderson, Alain Coc +2
The problem of estimating non-resonant astrophysical S-factors and thermonuclear reaction rates, based on measured nuclear cross sections, is of major interest for nuclear energy g…
The Magnetic Cataclysmic Variable LSQ1725-64
J. T. Fuchs, Bart H. Dunlap, E. Dennihy +7
We present new photometry and spectroscopy of the 94m eclipsing binary LSQ1725-64 that provide insight into the fundamental parameters and evolutionary state of this system. We con…
Outbursts in two new cool pulsating DA white dwarfs
Keaton J. Bell, J. J. Hermes, M. H. Montgomery +9
The unprecedented extent of coverage provided by Kepler observations recently revealed outbursts in two hydrogen-atmosphere pulsating white dwarfs (DAVs) that cause hours-long incr…
Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work
M. C. P. Bours, T. R. Marsh, S. G. Parsons +18
We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includ…
The Thermonuclear Runaway and the Classical Nova Outburst
S. Starrfield, C. Iliadis, W. R. Hix
Nova explosions occur on the white dwarf component of a Cataclysmic Variable binary stellar system that is accreting matter lost by its companion. When sufficient material has been…
Optical photometry and spectroscopy of the 1987A-like supernova 2009mw
K. Takáts, G. Pignata, M. Bersten +9
We present optical photometric and spectroscopic observations of the 1987A-like supernova (SN) 2009mw. Our and photometry covers 167 days of evolution, including…
The infrared spectral properties of Magellanic carbon stars
G. C. Sloan, K. E. Kraemer, I. McDonald +12
The Infrared Spectrograph on the Spitzer Space Telescope observed 184 carbon stars in the Magellanic Clouds. This sample reveals that the dust-production rate (DPR) from carbon sta…
GW Librae: A unique laboratory for pulsations in an accreting white dwarf
O. Toloza, B. T. Gaensicke, J. J. Hermes +22
Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmos…
Properties of Carbon-Oxygen White Dwarfs From Monte Carlo Stellar Models
C. E. Fields, R. Farmer, I. Petermann +2
We investigate properties of carbon-oxygen white dwarfs with respect to the composite uncertainties in the reaction rates using the stellar evolution toolkit, Modules for Experimen…
Why are rapidly rotating M dwarfs in the Pleiades so (infra)red? New period measurements confirm rotation-dependent color offsets from the cluster sequence
