Bayesian analysis to identify new star candidates in nearby young stellar kinematic groups
Lison Malo, René Doyon, David Lafrenière +4
We present a new method based on a Bayesian analysis to identify new members of nearby young kinematic groups. The analysis minimally takes into account the position, proper motion…
The International Deep Planet Survey I. The frequency of wide-orbit massive planets around A-stars
A. Vigan, J. Patience, C. Marois +8
Breakthrough direct detections of planetary companions orbiting A-type stars confirm the existence of massive planets at relatively large separations, but dedicated surveys are req…
The VAST Survey -- II. Orbital motion monitoring of A-type star multiples
Robert J. De Rosa, Jenny Patience, Arthur Vigan +11
As a part of our ongoing Volume-limited A-Star (VAST) adaptive optics survey, we have obtained observations of 26 binary systems with projected separations <100 AU, 13 of which hav…
