The Hawaii infrared parallax program. I. Ultracool binaries and the L/T transition
We present the first results from our high-precision infrared (IR) astrometry program at the
Canada–France–Hawaii Telescope. We measure parallaxes for 83 ultracool dwarfs …

LkCa 15: a young exoplanet caught at formation?
AL Kraus, MJ Ireland - The Astrophysical Journal, 2011 - iopscience.iop.org
Young and directly imaged exoplanets offer critical tests of planet-formation models that are
not matched by radial velocity surveys of mature stars. These targets have been extremely …

Mapping the shores of the Brown Dwarf desert. II. Multiple star formation in Taurus–Auriga
We have conducted a high-resolution imaging study of the Taurus–Auriga star-forming
region in order to characterize the primordial outcome of multiple star formation and the …

The impact of stellar multiplicity on planetary systems. I. The ruinous influence of close binary companions
The dynamical influence of binary companions is expected to profoundly influence planetary
systems. However, the difficulty of identifying planets in binary systems has left the …

No clear, direct evidence for multiple protoplanets orbiting LkCa 15: LkCa 15 bcd are likely inner disk signals
Two studies utilizing sparse aperture-masking (SAM) interferometry and H α differential
imaging have reported multiple Jovian companions around the young solar-mass star, LkCa …

A near-infrared interferometric survey of debris-disc stars-III. First statistics based on 42 stars observed with CHARA/FLUOR
Context. Dust is expected to be ubiquitous in extrasolar planetary systems owing to the
dynamical activity of minor bodies. Inner dust populations are, however, still poorly known …
