The GALEX View of "Boyajian's Star" (KIC 8462852)
James. R. A. Davenport, Kevin R. Covey, Riley W. Clarke +12
The enigmatic star KIC 8462852, informally known as "Boyajian's Star", has exhibited unexplained variability from both short timescale (days) dimming events, and years-long fading…
Nonlinear mean-field dynamo and prediction of solar activity
N. Safiullin, N. Kleeorin, S. Porshnev +2
We apply a nonlinear mean-field dynamo model which includes a budget equation for the dynamics of Wolf numbers to predict solar activity. This dynamo model takes into account the a…
3He-Rich Solar Energetic Particles in Helical Jets on the Sun
Radoslav Bucik, Davina E. Innes, Glenn M. Mason +3
Particle acceleration in stellar flares is ubiquitous in the Universe, however, our Sun is the only astrophysical object where energetic particles and their source flares can both…
First NuSTAR Limits on Quiet Sun Hard X-Ray Transient Events
Andrew J. Marsh, David M. Smith, Lindsay Glesener +16
We present the first results of a search for transient hard X-ray (HXR) emission in the quiet solar corona with the \textit{Nuclear Spectroscopic Telescope Array} (\textit{NuSTAR})…
HST Scattered Light Imaging and Modeling of the Edge-on Protoplanetary Disk ESO-H 569
Schuyler G. Wolff, Marshall D. Perrin, Karl Stapelfeldt +6
We present new HST ACS observations and detailed models for a recently discovered edge-on protoplanetary disk around ESO H 569 (a low-mass T Tauri star in the Cha I star forming…
Impact of convection and resistivity on angular momentum transport in dwarf novae
N. Scepi, G. Lesur, G. Dubus +1
The eruptive cycles of dwarf novae (DN) are thought to be due to a thermal-viscous instability in the accretion disk surrounding the white dwarf (WD). This model has long been know…
Comparison of Helioseismic Far-side Active Region Detections with STEREO Far-Side EUV Observations of Solar Activity
P. C. Liewer, J. Qiu, C. Lindsey
Seismic maps of the Sun's far hemisphere, computed from Doppler data from the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) are now being use…
A Catalog of Stellar Unified Properties (CATSUP) for 951 FGK-Stars Within 30 pc
Natalie R. Hinkel, Eric E. Mamajek, Margaret C. Turnbull +6
Almost every star in our Galaxy is likely to harbor a terrestrial planet, but accurate measurements of an exoplanet's mass and radius demands accurate knowledge of the properties o…
A near-infrared interferometric survey of debris-disk stars. VI. Extending the exozodiacal light survey with CHARA/JouFLU
Paul D. Nunez, N. J. Scott, B. Mennesson +11
We report the results of high-angular-resolution observations that search for exozodiacal light in a sample of main sequence stars and sub-giants. Using the "jouvence" of the fiber…
Identification of Young Stellar Variables with KELT for K2 II: The Upper Scorpius Association
Megan Ansdell, Ryan J. Oelkers, Joseph E. Rodriguez +13
High-precision photometry from space-based missions such as K2 and TESS enables detailed studies of young star variability. However, because space-based observing campaigns are oft…
Empirical Bolometric Fluxes and Angular Diameters of 1.6 Million Tycho-2 Stars and Radii of 350,000 Stars with \emph{Gaia} DR1 Parallaxes
Daniel J. Stevens, Keivan G. Stassun, B. Scott Gaudi
We present bolometric fluxes and angular diameters for over 1.6 million stars in the {\it Tycho-2} catalog, determined using previously-determined empirical color-temperature and c…
The Fundamental Stellar Parameters of FGK Stars in the SEEDS Survey
Evan A. Rich, John P. Wisniewski, Michael W. McElwain +59
Large exoplanet surveys have successfully detected thousands of exoplanets to-date. Utilizing these detections and non-detections to constrain our understanding of the formation an…
Chemical Abundance Analysis of Three -Poor, Metal-Poor Stars in the Ultra-Faint Dwarf Galaxy Horologium I
D. Q. Nagasawa, J. L. Marshall, J. D. Simon +68
We present chemical abundance measurements of three stars in the ultra-faint dwarf galaxy Horologium I, a Milky Way satellite discovered by the Dark Energy Survey. Using high resol…
Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020
Tianshu Wang, Wei Zhu, Shude Mao +83
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
The Herschel Planetary Nebula Survey (HerPlaNS) - a comprehensive dusty photoionization model of NGC6781
Masaaki Otsuka, Toshiya Ueta, Peter A. M. van Hoof +9
We perform a comprehensive analysis of the planetary nebula (PN) NGC6781 to investigate the physical conditions of each of its ionized, atomic, and molecular gas and dust component…
Magnetic fields in circumstellar disks: The potential of Zeeman observations
R. Brauer, S. Wolf, M. Flock
Context. Recent high angular resolution polarimetric continuum observations of circumstellar disks provide new insights into their magnetic field. However, direct constraints are l…
A survey for planetary-mass brown dwarfs in the Chamaeleon I star-forming region
T. L. Esplin, K. L. Luhman, J. K. Faherty +2
We have performed a search for planetary-mass brown dwarfs in the Chamaeleon I star-forming region using proper motions and photometry measured from optical and infrared images fro…
Angular Momentum Evolution of Young Stars in the Nearby Scorpius-Centaurus OB Association
Samuel N. Mellon, Eric E. Mamajek, Thomas E. Oberst +1
We report the results of a study of archival SuperWASP light curves for stars in Scorpius-Centaurus (Sco-Cen), the nearest OB association. We use SuperWASP time-series photometry t…
On the Age of the TRAPPIST-1 System
Adam J. Burgasser, Eric E. Mamajek
The nearby (d = 12 pc) M8 dwarf star TRAPPIST-1 (2MASS J23062928-0502285) hosts a compact system of at least seven exoplanets with sizes similar to Earth. Given its importance for…
SONS: The JCMT legacy survey of debris discs in the submillimetre
Wayne S. Holland, Brenda C. Matthews, Grant M. Kennedy +32
Debris discs are evidence of the ongoing destructive collisions between planetesimals, and their presence around stars also suggests that planets exist in these systems. In this pa…
