First light of VLT/HiRISE: High-resolution spectroscopy of young giant exoplanets
A. Vigan, M. El Morsy, M. Lopez +46
A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer thei…
SARG: the high resolution spectrograph
Gratton R., Bonanno G., Bruno P. +8
SARG is the high resolution spectrograph of TNG. It has been in operation since late spring 2000. SARG is a cross dispersed echelle spectrograph; it offers both single object and l…
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…
SPHERE IRDIS and IFS astrometric strategy and calibration
Anne-Lise Maire, Maud Langlois, Kjetil Dohlen +16
We present the current results of the astrometric characterization of the VLT planet finder SPHERE over 2 years of on-sky operations. We first describe the criteria for the selecti…
High precision radial velocities with GIANO spectra
I. Carleo, N. Sanna, R. Gratton +7
Radial velocities (RV) measured from near-infrared (NIR) spectra are a potentially excellent tool to search for extrasolar planets around cool or active stars. High resolution infr…
Performance of the VLT Planet Finder SPHERE II. Data analysis and Results for IFS in laboratory
D. Mesa, R. Gratton, A. Zurlo +33
We present the performance of the Integral Field Spectrograph (IFS) of SPHERE, the high-contrast imager for the ESO VLT telescope designed to perform imaging and spectroscopy of ex…
