A Disk around the Planetary-mass Companion GSC?06214-00210?b: Clues about the Formation of Gas Giants on Wide Orbits
Brendan P. Bowler,Michael C. Liu,Adam L. Kraus,Andrew W. Mann,Michael J. Ireland,Michael J. Ireland +5 more
TL;DR: In this article, Keck OSIRIS 1.1-1.8m adaptive optics integral field spectroscopy of the planetary-mass companion to GSC 06214-00210, a member of the ~5?Myr Upper Scorpius OB association, was presented.
Journal ArticleDOI
KECK LASER GUIDE STAR ADAPTIVE OPTICS MONITORING OF THE M8+L7 BINARY LHS 2397aAB: FIRST DYNAMICAL MASS BENCHMARK AT THE L/T TRANSITION* ** ** * ** * *
TL;DR: In this article, Keck LGS AO imaging and aperture masking observations of the M8+L7 binary LHS 2397aAB were used to determine a total dynamical mass of 0.146+/-0.014 MSun (153+/-15 MJup).
Journal ArticleDOI
NEW EVIDENCE FOR A SUBSTELLAR LUMINOSITY PROBLEM: DYNAMICAL MASS FOR THE BROWN DWARF BINARY Gl 417BC
Trent J. Dupuy,Trent J. Dupuy,Michael C. Liu,Michael J. Ireland,Michael J. Ireland,Michael J. Ireland +5 more
TL;DR: In this article, the authors present new evidence for a problem with cooling rates predicted by substellar evolutionary models that implies that model-derived masses in the literature for brown dwarfs and directly imaged planets may be too high.
Journal ArticleDOI
Kepler-445, Kepler-446 and the occurrence of compact multiples orbiting mid-M dwarf stars
Philip S. Muirhead,Andrew W. Mann,Andrew W. Mann,Andrew Vanderburg,Timothy D. Morton,Adam L. Kraus,Michael J. Ireland,Jonathan J. Swift,Gregory A. Feiden,Eric Gaidos,J. Zachary Gazak +10 more
TL;DR: In this paper, the authors confirm and characterize the exoplanetary systems Kepler-445 and Kepler-446: two mid-M dwarf stars, each with multiple, small, short-period transiting planets.
Journal ArticleDOI
Sparse aperture masking at the VLT. I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
Sylvestre Lacour,Peter G. Tuthill,Paola Amico,Michael J. Ireland,David Ehrenreich,Nuria Huélamo,Anne-Marie Lagrange +6 more
TL;DR: In this paper, a search for faint companions was performed using a detection strategy based on the analysis of closure phases recovered from interferograms recorded on the Conica camera, and the results demonstrate that SAM is a very competitive mode in the field of companion detection.
