Journal ArticleDOI
Direct imaging discovery of 12-14 Jupiter mass object orbiting a young binary system of very low-mass stars
P. Delorme,Jonathan Gagné,J. H. Girard,Anne-Marie Lagrange,G. Chauvin,M-E. Naud,David Lafrenière,René Doyon,Adric R. Riedel,M. Bonnefoy,L. Malo +10 more
TL;DR: In this article, the authors reported the direct imaging discovery of 2MASS J01033563-5515561(AB)b, a 12-14 MJup companion at a projected separation of 84 AU from a pair of young late M stars.

OSIRIS: infrared integral field spectrograph for the Keck adaptive optics system
James E. Larkin,A. Quirrenbach,Alfred Krabbe,Ted Aliado,Matthew Barczys,George Brims,John Canfield,Thomas M. Gasaway,David Lafrenière,Nick Magnone,Gunnar E. Skulason,Michael Spencer,David Sprayberry,Jason Weiss +13 more
TL;DR: The OSIRIS project as discussed by the authors uses an infrared transmissive lenslet array to sample a rectangular field of view at close to the Keck diffraction limit, achieving a relatively large field-of-view (FOV) while maintaining full broad-band spectral coverage at a resolution of 3900.
Proceedings ArticleDOI
Data reduction pipeline for OSIRIS, the new NIR diffraction-limited imaging field spectrograph for the Keck adaptive optics system
Alfred Krabbe,Tom Gasaway,Inseok Song,Christof Iserlohe,Jason Weiss,James E. Larkin,Matthew Barczys,David Lafrenière +7 more
TL;DR: OSIRIS as discussed by the authors is a near infrared diffraction limited imaging field spectrometer under development for the Keck observatory adaptive optics system and a data reduction software package is under development, aiming to provide the observer with a facility instrument allowing him to concentrate on science rather than dealing with instrumental as well as telescope and atmosphere related effects.

TL;DR: The Near InfraRed Planet Searcher (NIRPS) as discussed by the authors is a new ultra-stable infrared (YJH) spectrograph that will be installed on ESO's 3.6-metre Telescope in La Silla, Chile.
Planetary System and Star Formation Science with Non-Redundant Masking on JWST
Anand Sivaramakrishnan,Peter G. Tuthill,Michael J. Ireland,James P. Lloyd,F. Martinache,R. Soummer,René Doyon,David Lafrenière,M. Beaulieu,C. A. Beichman +9 more
TL;DR: Non-redundant masking (NRM) is a high contrast high resolution technique that is relevant for future space missions dedicated to either general astrophysics or extrasolar planetary astronomy.
