Unveiling the Infrared Excess of SIPS J2045-6332: Evidence for a Young Stellar Object with Potential Low-Mass Companion
Michiharu Hyogo, Thomas P. Bickle, Joseph R. Biggs +20
The Disk Detective project, a citizen science initiative, aims to identify circumstellar discs around stars by detecting objects with infrared (IR) excess using data from the Wide-…
Astro2020 Science White Paper: Fundamental Physics with Brown Dwarfs: The Mass-Radius Relation
Adam Burgasser, Isabelle Baraffe, Matthew Browning +17
The lowest-mass stars, brown dwarfs and giant exoplanets span a minimum in the mass-radius relationship that probes the fundamental physics of extreme states of matter, magnetism,…
Magnetic Fields on the Flare Star Trappist-1: Consequences for Radius Inflation and Planetary Habitability
D. J. Mullan, J. MacDonald, S. Dieterich +1
We construct evolutionary models of Trappist-1 in which magnetic fields impede the onset of convection according to a physics-based criterion. In the models that best fit all obser…
Dynamical Masses of Eps Ind B and C: Two Massive Brown Dwarfs at the Edge of the Stellar-Substellar Boundary
Sergio B. Dieterich, Alycia J. Weinberger, Alan P. Boss +6
We report individual dynamical masses for the brown dwarfs Epsilon Indi B and C, which have spectral types of T1.5 and T6, respectively, measured from astrometric orbit mapping. Ou…
The Solar Neighborhood XLIV: RECONS Discoveries within 10 Parsecs
Todd J. Henry, Wei-Chun Jao, Jennifer G. Winters +7
We describe the 44 systems discovered to be within 10 parsecs of the Sun by the RECONS team, primarily via the long-term astrometry program at CTIO that began in 1999. The systems…
The discovery and mass measurement of a new ultra-short-period planet: EPIC~228732031b
Fei Dai, Joshua N. Winn, Davide Gandolfi +51
We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, EPIC~2…
The Solar Neighborhood XXXVI: The Long-Term Photometric Variability of Nearby Red Dwarfs in the VRI Optical Bands
Altonio D. Hosey, Todd J. Henry, Wei-Chun Jao +5
We present an analysis of long-term photometric variability for nearby red dwarfs at optical wavelengths. The sample consists of 264 M dwarfs south of DEC = +30 with V-K = 3.96-9.1…
The Solar Neighborhood XXXV: Distances to 1404 M Dwarf Systems Within 25 pc in the Southern Sky
Jennifer G. Winters, Todd J. Henry, John C. Lurie +11
We present trigonometric, photometric, and photographic distances to 1748 southern (0) M dwarf systems with 0\farcs18 yr, of which 1404 are believed to…
The Solar Neighborhood. XXXIII. Parallax Results from the CTIOPI 0.9m Program: Trigonometric Parallaxes of Nearby Low-Mass Active and Young Systems
Adric R. Riedel, Charlie T. Finch, Todd J. Henry +14
We present basic observational data and association membership analysis for 45 young and active low-mass stellar systems from the ongoing RECONS photometry and astrometry program a…
The Solar Neighborhood XXXII. The Hydrogen Burning Limit
Sergio B. Dieterich, Todd J. Henry, Wei-Chun Jao +4
We construct a Hertzsprung-Russell diagram for the stellar/substellar boundary based on a sample of 63 objects ranging in spectral type from M6V to L4. We report newly observed VRI…
The Solar Neighborhood XXX: Fomalhaut C
Eric E. Mamajek, Jennifer L. Bartlett, Andreas Seifahrt +11
LP 876-10 is a nearby active M4 dwarf in Aquarius at a distance of 7.6 pc. The star is a new addition to the 10-pc census, with a parallax measured via the Research Consortium on N…
The Solar Neighborhood XXVIII: The Multiplicity Fraction of Nearby Stars from 5 to 70 AU and the Brown Dwarf Desert Around M Dwarfs
Sergio B. Dieterich, Todd J. Henry, David A. Golimowski +2
We report on our analysis of HST/NICMOS snapshot high resolution images of 255 stars in 201 systems within ~10 parsecs of the Sun. Photometry was obtained through filters F110W, F1…
The Solar Neighborhood IX: Hubble Space Telescope Detections of Companions to Five M and L Dwarfs within 10 pc of the Sun
D. A. Golimowski, T. J. Henry, J. E. Krist +10
We report the detections of low-mass companions to five M and L dwarfs within 10 pc of the Sun using the Hubble Space Telescope (HST) Near-Infrared Camera and Multi-Object Spectrom…
