Advancing European High-Contrast Imaging R&D Towards the Habitable Worlds Observatory
Iva Laginja, Óscar Carrión-González, Romain Laugier +31
The Habitable Worlds Observatory (HWO) will enable a transformative leap in the direct imaging and characterization of Earth-like exoplanets. For this, NASA is focusing on early in…
DL4DS -- Deep Learning for empirical DownScaling
Carlos Alberto Gomez Gonzalez
A common task in Earth Sciences is to infer climate information at local and regional scales from global climate models. Dynamical downscaling requires running expensive numerical…
Characterization of low-mass companion HD 142527 B
V. Christiaens, S. Casassus, O. Absil +10
The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and se…
Discovery of a point-like source and a third spiral arm in the transition disk around the Herbig Ae star MWC 758
M. Reggiani, V. Christiaens, O. Absil +20
Transition disks offer the extraordinary opportunity to look for newly born planets and investigate the early stages of planet formation. In this context we observed the Herbig A5…
A New Standard for Assessing the Performance of High Contrast Imaging Systems
Rebecca Jensen-Clem, Dimitri Mawet, Carlos A. Gomez Gonzalez +8
As planning for the next generation of high contrast imaging instruments (e.g. WFIRST, HabEx, and LUVOIR, TMT-PFI, EELT-EPICS) matures, and second-generation ground-based extreme a…
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…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
VLT/SPHERE robust astrometry of the HR8799 planets at milliarcsecond-level accuracy Orbital architecture analysis with PyAstrOFit
Olivier Wertz, Olivier Absil, Carlos. A. Gómez González +4
HR8799 is orbited by at least four giant planets, making it a prime target for the recently commissioned Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT/SPHERE). As such…
Direct exoplanet detection and characterization using the ANDROMEDA method: Performance on VLT/NaCo data
F. Cantalloube, D. Mouillet, L. M. Mugnier +6
Context. The direct detection of exoplanets with high-contrast imaging requires advanced data processing methods to disentangle potential planetary signals from bright quasi-static…
The VORTEX project: first results and perspectives
Olivier Absil, Dimitri Mawet, Christian Delacroix +15
(abridged) Vortex coronagraphs are among the most promising solutions to perform high contrast imaging at small angular separations. They feature a very small inner working angle,…
