The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
NACO-SDI imaging of known companion host stars from the AAPS and Keck planet search surveys
J. S. Jenkins, H. R. A. Jones, B. Biller +8
Direct imaging of brown dwarfs as companions to solar-type stars can provide a wealth of well-constrained data to "benchmark" the physics of such objects, since quantities like met…
First determination of the dynamical mass of a binary L dwarf
H. Bouy, G. Duchene, R. Koehler +11
We present here the results of astrometric, photometric and spectroscopic observations leading to the determination of the orbit and dynamical masses of the binary L dwarf 2MASSW J…
Starfinder: a code for crowded stellar fields analysis
E. Diolaiti, O. Bendinelli, D. Bonaccini +3
Starfinder is an IDL code for the deep analysis of stellar fields, designed for well-sampled images with high and low Strehl factor. An important feature is represented by the poss…
Gliese 569B: A young multiple brown dwarf system?
M. A. Kenworthy, K-H. Hofmann, L. Close +8
The nearby late M star Gliese 569B was recently found by adaptive optics imaging to be a double with separation ~1 AU. To explore the orbital motion and masses, we have undertaken…
Analysis of isoplanatic high resolution stellar fields by Starfinder code
E. Diolaiti, O. Bendinelli, D. Bonaccini +3
We describe a new code for the deep analysis of stellar fields, designed for Adaptive Optics Nyquist-sampled images with high and low Strehl ratio. The Point Spread Function is ext…
