Hot Subdwarf All Southern Sky Fast Transit Survey with the Evryscope
Jeffrey K. Ratzloff, Brad N. Barlow, Peter Nemeth +6
We have conducted a survey of candidate hot subdwarf stars in the southern sky searching for fast transits, eclipses, and sinusoidal like variability in the Evryscope light curves.…
Magnetic Inflation and Stellar Mass. V. Intensification and saturation of M dwarf absorption lines with Rossby number
Philip S. Muirhead, Mark J. Veyette, Elisabeth R. Newton +2
In young sun-like stars and field M dwarf stars, chromospheric and coronal magnetic activity indicators such as H, X-ray and radio emission are known to saturate with low Rossby…
Stellar Pulsation and the Production of Dust and Molecules in Galactic Carbon Stars
Kathleen E. Kraemer, G. C. Sloan, Luke D. Keller +3
New infrared spectra of 33 Galactic carbon stars from FORCAST on SOFIA reveal strong connections between stellar pulsations and the dust and molecular chemistry in their circumstel…
Robo-AO Kepler Asteroseismic Survey. II. Do Stellar Companions Inhibit Stellar Oscillations?
Jessica Schonhut-Stasik, Daniel Huber, Christoph Baranec +7
The Kepler space telescope observed over 15,000 stars for asteroseismic studies. Of these, 75% of dwarfs (and 8% of giants) were found to show anomalous behavior: such as suppresse…
Asymptotic Giant Branch Stars in the Nearby Dwarf Galaxy Leo P
Steven R. Goldman, Martha L. Boyer, Kristen B. McQuinn +7
We have conducted a highly sensitive census of the evolved-star population in the metal-poor dwarf galaxy Leo P and detected four asymptotic giant branch (AGB) star candidates. Leo…
Carbon-Oxygen Classical Novae are Galactic Li Producers as well as Potential Supernova Ia Progenitors
Sumner Starrfield, Maitrayee Bose, Christian Iliadis +3
We report on studies of Classical Nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on Carbon Oxygen (CO) white dwarfs (WDs). We vary both the mas…
WISE J072003.20-084651.2B Is A Massive T Dwarf
Trent J. Dupuy, Michael C. Liu, William M. J. Best +21
We present individual dynamical masses for the nearby M9.5+T5.5 binary WISE J072003.20084651.2AB, a.k.a. Scholz's star. Combining high-precision CFHT/WIRCam photocenter astromet…
A 9-Hr CV With One Outburst in 4 Years of Kepler Data
Zhifei Yu, John Thorstensen, Saul Rappaport +11
During a visual search through the Kepler main-field lightcurves, we have discovered a cataclysmic variable (CV) that experienced only a single 4-day long outburst over four years,…
Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
Pier-Emmanuel Tremblay, Gilles Fontaine, Nicola Pietro Gentile Fusillo +7
White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years. These stars, which are supported by electron degeneracy pressure, reach densiti…
Analysis of Helium-Rich White Dwarfs Polluted by Heavy Elements in the Gaia Era
S. Coutu, P. Dufour, P. Bergeron +4
We present a homogeneous analysis of 1023 DBZ/DZ(A) and 319 DQ white dwarf stars taken from the Montreal White Dwarf Database. This represents a significant increase over the previ…
A Volume Limited Sample of Cataclysmic Variables from DR2: Space Density and Population Properties
A. F. Pala, B. T. Gänsicke, E. Breedt +15
We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the ESA $\mathit{Gaia…
EvryFlare II: Rotation Periods of the Cool Flare Stars in TESS Across Half the Southern Sky
Ward S. Howard, Hank Corbett, Nicholas M. Law +6
We measure rotation periods and sinusoidal amplitudes in Evryscope light curves for 122 two-minute K5-M4 TESS targets selected for strong flaring. The Evryscope array of telescopes…
The Revised TESS Input Catalog and Candidate Target List
Keivan G. Stassun, Ryan J. Oelkers, Martin Paegert +33
We describe the catalogs assembled and the algorithms used to populate the revised TESS Input Catalog (TIC), based on the incorporation of the Gaia second data release. We also des…
Effective Temperatures of Low-Mass Stars from High-Resolution H-band Spectroscopy
Ricardo López-Valdivia, Gregory N. Mace, Kimberly R. Sokal +9
High-resolution, near-infrared spectra will be the primary tool for finding and characterizing Earth-like planets around low-mass stars. Yet, the properties of exoplanets can not b…
Variables in the Southern Polar Region Evryscope 2016 Dataset
Jeffrey K. Ratzloff, Henry T. Corbett, Nicholas M. Law +6
The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to search f…
Complex Rotational Modulation of Rapidly Rotating M-Stars Observed with TESS
Z. Zhan, M. N. Günther, S. Rappaport +23
We have searched for short periodicities in the light curves of stars with cooler than 4000 K made from 2-minute cadence data obtained in TESS sectors 1 and 2. Herein…
EvryFlare I: Long-term Evryscope Monitoring of Flares from the Cool Stars Across Half the Southern Sky
