Speckle lifetime in XAO coronagraphic images: temporal evolution of SPHERE coronagraphic images
J. Milli, T. Banas, D. Mouill +11
The major source of noise in high-contrast imaging is the presence of slowly evolving speckles that do not average with time. The temporal stability of the point-spread-function (P…
The ERIS Adaptive Optics System
A. Riccardi, S. Esposito, G. Agapito +19
ERIS is the new AO instrument for VLT-UT4 led by a Consortium of Max-Planck Institut fuer Extraterrestrische Physik, UK-ATC, ETH-Zurich, ESO and INAF. The ERIS AO system provides N…
Increasing the sensitivity of a Shack-Hartmann sensor
Markus Kasper, Douglas Looze, Stefan Hippler +2
The Max-Planck institutes for astronomy (MPIA) and for extraterrestrial physics (MPE) run an adaptive optics (AO) system with a laser guide star at the 3.5 m telescope on Calar Alt…
Direct Imaging Discovery of a Jovian Exoplanet Within a Triple Star System
Kevin Wagner, Dániel Apai, Markus Kasper +4
Direct imaging allows for the detection and characterization of exoplanets via their thermal emission. We report the discovery via imaging of a young Jovian planet in a triple star…
New Circumstellar Structure in the T Tauri System
M. Kasper, K. K. R. Santhakumari, T. M. Herbst +1
The immediate vicinity of T Tauri was observed with the new high-contrast imaging instrument SPHERE at the VLT to resolve remaining mysteries of the system, such as the putative sm…
High-Cadence, High-Contrast Imaging for Exoplanet Mapping: Observations of the HR 8799 Planets with VLT/SPHERE Satellite Spot-Corrected Relative Photometry
Daniel Apai, Markus Kasper, Andrew Skemer +6
Time-resolved photometry is an important new probe of the physics of condensate clouds in extrasolar planets and brown dwarfs. Extreme adaptive optics systems can directly image pl…
