We report the discovery of an eclipsing companion to NLTT 41135, a nearby M5 dwarf that was already known to have a wider, slightly more massive common proper motion companion, NLTT 41136, at 2".4 separation. Analysis of combined-light and RV curves of the system indicates that NLTT 41135B is a (31-34) ± 3M_(Jup) brown dwarf (where the range depends on the unknown metallicity of the host star) on a circular orbit. The visual M dwarf pair appears to be physically bound, so the system forms a… Expand
LHS 6343 C: A TRANSITING FIELD BROWN DWARF DISCOVERED BY THE KEPLER MISSION ∗
We report the discovery of a brown dwarf that transits one member of the M+M binary system LHS 6343 AB every 12.71 days. The transits were discovered using photometric data from the Kepler publicExpand
Four New Eclipsing Mid M-dwarf Systems from the New Luyten Two Tenths Catalog
Using data from the MEarth-North and MEarth-South transit surveys, we present the detection of eclipses in four mid M-dwarf systems: LP 107-25, LP 261-75, LP 796-24, and LP 991-15. Combining theExpand
A brown dwarf orbiting an M-dwarf: MOA 2009–BLG–411L
Context. Caustic crossing is the clearest signature of binary lenses in microlensing. In the present context, this signature is diluted by the large source star but a detailed analysis has allowedExpand
Post Common Envelope Binaries from SDSS. XV: Accurate stellar parameters for a cool 0.4-solar mass white dwarf and a 0.16-solar mass M-dwarf in a 3 hour eclipsing binary
We identify SDSSJ121010.1+334722.9 as an eclipsing post-common-envelope binary, with an orbital period of P ~ 3 hrs, containing a very cool, low-mass, DAZ white dwarf and a low-mass main-sequenceExpand
NGTS-7Ab: an ultrashort-period brown dwarf transiting a tidally locked and active M dwarf
We present the discovery of NGTS-7Ab, a high-mass brown dwarf transiting an M dwarf with a period of 16.2 h, discovered as part of the Next Generation Transit Survey (NGTS). This is the shortestExpand
Characterizing the Cool KOIs. VII. Refined Physical Properties of the Transiting Brown Dwarf LHS 6343 C
We present an updated analysis of LHS 6343, a triple system in the Kepler field which consists of a brown dwarf transiting one member of a widely-separated M+M binary system. By analyzing the fullExpand
An eclipsing double-line spectroscopic binary at the stellar/substellar boundary in the Upper Scorpius OB association
We aim at constraining evolutionary models at low mass and young ages by identifying interesting transiting system members of the nearest OB association to the Sun, Upper Scorpius, targeted by theExpand
TOI–1278 B: SPIRou Unveils a Rare Brown Dwarf Companion in Close-in Orbit around an M Dwarf
We present the discovery of an 18.5 ± 0.5 M Jup brown dwarf (BD) companion to the M0V star TOI–1278. The system was first identified through a percent-deep transit in Transiting Exoplanet SurveyExpand
TOI-503: The First Known Brown-dwarf Am-star Binary from the TESS Mission
We report the discovery of an intermediate-mass transiting brown dwarf (BD), TOI-503b, from the TESS mission. TOI-503b is the first BD discovered by TESS, and it has circular orbit around aExpand
WASP-30b: A 61 M brown dwarf transiting a V = 12, F8 star
TLDR
The location of WASP-30b in the minimum of the mass-radius relation is consistent with the quantitative prediction of Chabrier & Baraffe, thus confirming the theory. Expand

Discovery of two young brown dwarfs in an eclipsing binary system
TLDR
This work reports the discovery of a brown-dwarf eclipsing binary system, in the Orion Nebula star-forming region, from which direct measurements of mass and radius establish both objects as brown dwarfs, and finds that the less-massive brown dwarf is the hotter of the pair. Expand
