A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
Comprehensive analysis of HD 105, a young Solar System analog
J. P. Marshall, J. Milli, É. Choquet +5
HD~105 is a nearby, pre-main sequence G0 star hosting a moderately bright debris disc (). HD~105 and its surroundings might therefore…
Origin of the asymmetry of the wind driven halo observed in high contrast images
F. Cantalloube, E Por, K. Dohlen +9
The latest generation of high contrast instruments dedicated to exoplanets and circumstellar disks imaging are equipped with extreme adaptive optics and coronagraphs to reach contr…
SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry
H. M. Schmid, A. Bazzon, R. Roelfsema +59
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wa…
Low Wind Effect on VLT/SPHERE : impact, mitigation strategy, and results
Julien Milli, Markus Kasper, Pierre Bourget +14
The low wind effect is a phenomenon disturbing the phase of the wavefront in the pupil of a large telescope obstructed by spiders, in the absence of wind. It can be explained by th…
Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
M. Keppler, M. Benisty, A. Müller +123
Young circumstellar disks are of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of planet cand…
