Semi-analytic calculations for extended mid-Infrared emission associated with FU Ori-type objects
Michihiro Takami, Pin-Gao Gu, Gilles Otten +4
(Aims) Near-infrared imaging polarimetry at high-angular resolutions has revealed intriguing distribution of circumstellar dust towards FU Ori-type objects (FUors). These dust grai…
The W. M. Keck Observatory infrared vortex coronagraph and a first image of HIP79124 B
Eugene Serabyn, Elsa Huby, Keith Matthews +22
An optical vortex coronagraph has been implemented within the NIRC2 camera on the Keck II telescope and used to carry out on-sky tests and observations. The development of this new…
Discovery of a low-mass companion inside the debris ring surrounding the F5V star HD206893
Julien Milli, Pascale Hibon, Valentin Christiaens +30
Uncovering the ingredients and the architecture of planetary systems is a very active field of research that has fuelled many new theories on giant planet formation, migration, com…
Optimizing the subwavelength grating of L-band Annular Groove Phase Masks for high coronagraphic performance
Ernesto Vargas Catalan, Elsa Huby, Pontus Forsberg +9
Context. The Annular Groove Phase Mask (AGPM) is one possible implementation of the vector vortex coronagraph, where the helical phase ramp is produced by a concentric subwavelengt…
Three years of harvest with the vector vortex coronagraph in the thermal infrared
Olivier Absil, Dimitri Mawet, Mikael Karlsson +25
For several years, we have been developing vortex phase masks based on sub-wavelength gratings, known as Annular Groove Phase Masks. Etched onto diamond substrates, these AGPMs are…
Annular Groove Phase Mask coronagraph in diamond for mid-IR wavelengths: manufacturing assessment and performance analysis
Christian Delacroix, Pontus Forsberg, Mikael Karlsson +7
Phase-mask coronagraphs are known to provide high contrast imaging capabilities while preserving a small inner working angle, which allows searching for exoplanets or circumstellar…
