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…
Exploring the RCrA environment with SPHERE: Discovery of a new stellar companion
D. Mesa, M. Bonnefoy, R. Gratton +39
Aims. R Coronae Australis (R CrA) is the brightest star of the Coronet nebula of the Corona Australis (CrA) star forming region. It has very red colors, probably due to dust absorp…
Uncrowding R 136 from VLT-SPHERE extreme adaptive optics
Z. Khorrami, F. Vakili, T. Lanz +12
This paper presents the sharpest near-IR images of the massive cluster R136 to date, based on the extreme adaptive optics of the SPHERE focal instrument implemented on the ESO/VLT…
Shadows cast on the transition disk of HD 135344B. Multiwavelength VLT/SPHERE polarimetric differential imaging
T. Stolker, C. Dominik, H. Avenhaus +35
The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a transition stage and shows many intriguing structures both in scattered light and thermal (sub-)milli…
VLT/SPHERE deep insight of NGC 3603's core: Segregation or confusion?
Z. Khorrami, T. Lanz, F. Vakili +19
We present new near-infrared photometric measurements of the core of the young massive cluster NGC 3603 obtained with extreme adaptive optics. The data were obtained with the SPHER…
First light of the VLT planet finder SPHERE. III. New spectrophotometry and astrometry of the HR8799 exoplanetary system
A. Zurlo, A. Vigan, R. Galicher +70
The planetary system discovered around the young A-type HR8799 provides a unique laboratory to: a) test planet formation theories, b) probe the diversity of system architectures at…
Discovery of a Low-Mass Companion to the F7V star HD 984
T. Meshkat, M. Bonnefoy, E. E. Mamajek +8
We report the discovery of a low-mass companion to the nearby (d = 47 pc) F7V star HD 984. The companion is detected 0.19" away from its host star in the L' band with the Apodizing…
Depletion of molecular gas by an accretion outburst in a protoplanetary disk
A. Banzatti, K. M. Pontoppidan, S. Bruderer +2
We investigate new and archival 3-5 m high resolution ( km s) spectroscopy of molecular gas in the inner disk of the young solar-mass star EX Lupi, taken during an…
Characterizing Exoplanets in the Visible and Infrared: A Spectrometer Concept for the EChO Space Mission
A. M. Glauser, R. van Boekel, O. Krause +30
Transit-spectroscopy of exoplanets is one of the key observational techniques to characterize the extrasolar planet and its atmosphere. The observational challenges of these measur…
EChO - Exoplanet Characterisation Observatory
G. Tinetti, J. P. Beaulieu, T. Henning +131
A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
Structure and Composition of Two Transitional Circumstellar Disks in Corona Australis
A. M. Hughes, S. M. Andrews, D. J. Wilner +10
The late stages of evolution of the primordial circumstellar disks surrounding young stars are poorly understood, yet vital to constrain theories of planet formation. We consider b…
