Insights into the planetary dynamics of HD 206893 with ALMA
S. Marino, A. Zurlo, V. Faramaz +8
Radial substructure in the form of rings and gaps has been shown to be ubiquitous among protoplanetary discs. This could be the case in exoKuiper belts as well, and evidence for th…
The impact of climate change on astronomical observations
Faustine Cantalloube, Julien Milli, Christoph Böhm +5
Climate change is affecting and will increasingly affect astronomical observations. In this paper, we investigated the role some key weather parameters play in the quality of astro…
CS Cha B: A disc-obscured M-type star mimicking a polarised planetary companion
S. Y. Haffert, R. G. van Holstein, C. Ginski +6
Context. Direct imaging provides a steady flow of newly discovered giant planets and brown dwarf companions. These multi-object systems can provide information about the formation…
Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
The challenge of measuring the phase function of debris disks. Application to HR\,4796
J. Olofsson, J. Milli, A. Bayo +2
Abridged: Debris disks are valuable systems to study dust properties. Because they are optically thin at all wavelengths, we have direct access to the properties of dust grains. On…
Possible evidence of ongoing planet formation in AB Aurigae. A showcase of the SPHERE/ALMA synergy
A. Boccaletti, E. Di Folco, E. Pantin +8
Context. Planet formation is expected to take place in the first million years of a planetary system through various processes, which remain to be tested through observations. Aims…
Increasing the raw contrast of VLT/SPHERE with the dark hole technique. I. Simulations and validation on the internal source
Axel Potier, Raphaël Galicher, Pierre Baudoz +7
Context. Since 1995 and the first discovery of an exoplanet orbiting a main-sequence star, 4000 exoplanets have been discovered using several techniques. However, only a few of the…
Searching for the near infrared counterpart of Proxima c using multi-epoch high contrast SPHERE data at VLT
R. Gratton, A. Zurlo, H. Le Coroller +43
Proxima Centauri is known to host an earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, the ex…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
The wind-driven halo in high-contrast images I: analysis from the focal plane images of SPHERE
Faustine Cantalloube, Ollie Farley, Julien Milli +9
Context. The wind driven halo is a feature observed within the images delivered by the latest generation of ground-based instruments equipped with an extreme adaptive optics system…
