Is the HD 15115 inner disk really asymmetrical ?
J. Mazoyer, A. Boccaletti, J. -C. Augereau +3
Context. Debris disks are intrinsically connected to the planetary system's formation and evolution. The development of high-contrast imaging techniques in the past 20 years is now…
An aperture masking mode for the MICADO instrument
S. Lacour, P. Baudoz, E. Gendron +8
MICADO is a near-IR camera for the Europea ELT, featuring an extended field (75" diameter) for imaging, and also spectrographic and high contrast imaging capabilities. It has been…
Physical and orbital properties of Beta Pictoris b
M. Bonnefoy, G. -D. Marleau, R. Galicher +13
The intermediate-mass star Beta Pictoris is known to be surrounded by a structured edge-on debris disk within which a gas giant planet was discovered orbiting at 8-10 AU. The physi…
GPI PSF subtraction with TLOCI: the next evolution in exoplanet/disk high-contrast imaging
Christian Marois, Carlos Correia, Raphael Galicher +4
To directly image exoplanets and faint circumstellar disks, the noisy stellar halo must be suppressed to a high level. To achieve this feat, the angular differential imaging observ…
Gemini Planet Imager Observational Calibrations II: Detector Performance and Calibration
Patrick Ingraham, Marshall D. Perrin, Naru Sadakuni +7
The Gemini Planet Imager is a newly commissioned facility instrument designed to measure the near-infrared spectra of young extrasolar planets in the solar neighborhood and obtain…
Search for cool giant exoplanets around young and nearby stars - VLT/NaCo near-infrared phase-coronagraphic and differential imaging
A. -L. Maire, A. Boccaletti, J. Rameau +8
[Abridged] Context. Spectral differential imaging (SDI) is part of the observing strategy of current and future high-contrast imaging instruments. It aims to reduce the stellar spe…
