TL;DR: The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument as discussed by the authors is a multiband instrument which makes use of light from 600 to 2500 nm, allowing for coronagraphic direct exoplanet imaging of the inner 3λ/D from the stellar host.
Journal ArticleDOI
Mapping the shores of the brown dwarf desert. ii. multiple star formation in taurus-auriga
TL;DR: In this paper, the authors 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 extent of the brown dwarf desert.
Journal ArticleDOI
The Role of Multiplicity in Disk Evolution and Planet Formation
TL;DR: In this paper, a combined multiplicity/disk census of Taurus-Auriga, plus a restricted sample of close binaries in other regions, was compiled to explore the role of multiplicity in disk evolution.
Journal ArticleDOI
Mapping the Shores of the Brown Dwarf Desert. I. Upper Scorpius
TL;DR: In this article, a survey for stellar and substellar companions to 82 young stars in the nearby OB association Upper Scorpius was presented, revealing 12 new binary companions that lay below the detection limits of traditional high-resolution imaging; they also summarize a complementary snapshot imaging survey that discovered seven directly resolved companions.
Journal ArticleDOI
Two wide planetary-mass companions to solar-type stars in upper scorpius
TL;DR: In this paper, an adaptive optics imaging survey was conducted for wide (~50-500 AU) companions to solar-type stars in Upper Scorpius, and two detections correspond to approximately 4% of the solar type stars having companions in the 6-20 M_J mass and ∼200-500AU separation range.
