SPHERE RefPlanets: Search for epsilon Eridani b and warm dust

C. Tschudi, H. M. Schmid, M. Nowak +35

We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…

New binaries from the SHINE survey

M. Bonavita, R. Gratton, S. Desidera +67

We present the multiple stellar systems observed within the SpHere INfrared survey for Exoplanet (SHINE). SHINE searched for substellar companions to young stars using high contras…

Investigating three Sirius-like systems with SPHERE

R. Gratton, V. D'Orazi, T. A. Pacheco +61

Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…

HD 117214 debris disk: scattered-light images and constraints on the presence of planets

N. Engler, C. Lazzoni, R. Gratton +34

We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…

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…

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…
