Theoretical limits on magnetic field strengths in low-mass stars
Matthew K. Browning, Maria A. Weber, Gilles Chabrier +1
Observations have suggested that some low-mass stars have larger radii than predicted by 1-D structure models. Some theoretical models have invoked very strong interior magnetic fi…
Far-Infrared Dust Temperatures and Column Densities of the MALT90 Molecular Clump Sample
Andrés E. Guzmán, Patricio Sanhueza, Yanett Contreras +4
We present dust column densities and dust temperatures for young high-mass molecular clumps from the Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey, derived fro…
The rotation and Galactic kinematics of mid M dwarfs in the Solar Neighborhood
Elisabeth R. Newton, Jonathan Irwin, David Charbonneau +3
Rotation is a directly-observable stellar property, and drives magnetic field generation and activity through a magnetic dynamo. Main sequence stars with masses below approximately…
Open Clusters as Probes of the Galactic Magnetic Field: I. Cluster Properties
Sadia Hoq, Dan Clemens
Stars in open clusters are powerful probes of the intervening Galactic magnetic field, via background starlight polarimetry, because they provide constraints on the magnetic field…
The Heliocentric Distance Where the Deflections and Rotations of Solar Coronal Mass Ejections Occur
C. Kay, M. Opher
Understanding the trajectory of a coronal mass ejection (CME), including any deflection from a radial path, and the orientation of its magnetic field is essential for space weather…
Motion Verified Red Stars (MoVeRS): A Catalog of Proper Motion Selected Low-mass Stars from WISE, SDSS, and 2MASS
Christopher A. Theissen, Andrew A. West, Saurav Dhital
We present a photometric catalog of 8,735,004 proper motion selected low-mass stars (KML-spectral types) within the Sloan Digital Sky Survey (SDSS) footprint, from the combined SDS…
A Catalog of GALEX Ultraviolet Emission from Spectroscopically Confirmed M Dwarfs
David O. Jones, Andrew A. West
We present a catalog of GALEX Near-UV (NUV) and Far-UV (FUV) photometry for the Palomar/MSU and SDSS DR7 spectroscopic M dwarf catalogs. The catalog contains NUV measurements match…
An Activity-Rotation Relationship and Kinematic Analysis of Nearby Mid-to-Late-type M Dwarfs
Andrew A. West, Kolby L. Weisenburger, Jonathan Irwin +4
Using spectroscopic observations and photometric light curves of 238 nearby M dwarfs from the MEarth exoplanet transit survey, we examine the relationships between magnetic activit…
A Pan-STARRS1 study of the relationship between wide binarity and planet occurrence in the Kepler field
N. R. Deacon, A. L. Kraus, A. W. Mann +9
The NASA Kepler mission has revolutionised time-domain astronomy and has massively expanded the number of known extrasolar planets. However, the effect of wide multiplicity on exop…
YSOVAR: mid-infrared variability of young stellar objects and their disks in the cluster IRAS 20050+2720
K. Poppenhaeger, A. M. Cody, K. R. Covey +12
We present a time-variability study of young stellar objects in the cluster IRAS 20050+2720, performed at 3.6 and 4.5 micron with the Spitzer Space Telescope; this study is part of…
Inclination-Induced Polarization of Scattered Millimeter Radiation from Protoplanetary Disks: The Case of HL Tau
Haifeng Yang, Zhi-Yun Li, Leslie Looney +1
Spatially resolved polarized millimeter/submillimeter emission has been observed in the disk of HL Tau and two other young stellar objects. It is usually interpreted as coming from…
Linking Stellar Coronal Activity and Rotation at 500 Myr: A Deep Chandra Observation of M37
Alejandro Núñez, Marcel A. Agüeros, Kevin R. Covey +9
Empirical calibrations of the stellar age-rotation-activity relation (ARAR) rely on observations of the co-eval populations of stars in open clusters. We used the Chandra X-ray Obs…
A model of the heliosphere with jets
J. F. Drake, M. Swisdak, M. Opher
An analytic model of the heliosheath (HS) between the termination shock (TS) and the heliopause (HP) is developed in the limit in which the interstellar flow and magnetic field are…
The Brown Dwarf Kinematics Project (BDKP). IV. Radial Velocities of 85 Late-M and L dwarfs with MagE
Adam J. Burgasser, Sarah E. Logsdon, Jonathan Gagne +6
Radial velocity measurements are presented for 85 late M- and L-type very low mass stars and brown dwarfs obtained with the Magellan Echellette (MagE) spectrograph. Targets primari…
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…
SLoWPoKES-II: 100,000 Wide Binaries Identified in SDSS without Proper Motions
Saurav Dhital, Andrew A. West, Keivan G. Stassun +2
We present the SLoWPoKES-II catalog of low-mass visual binaries identified from the Sloan Digital Sky Survey by matching photometric distances. The candidate pairs are vetted by co…
