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…
Exoplanet science with a space-based mid-infrared nulling interferometer
Sascha P. Quanz, Jens Kammerer, Denis Defrère +3
One of the long-term goals of exoplanet science is the (atmospheric) characterization of a large sample (>100) of terrestrial planets to assess their potential habitability and ove…
Characterizing the atmosphere of Proxima b with a space-based mid-infrared nulling interferometer
D. Defrère, A. Léger, O. Absil +9
Proxima b is our nearest potentially rocky exoplanet and represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35~…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
Wavelet based speckle suppression for exoplanet imaging - Application of a de-noising technique in the time domain
Markus J. Bonse, Sascha P. Quanz, Adam Amara
Context. High-contrast exoplanet imaging is a rapidly growing field as can be seen through the significant resources invested. In fact, the detection and characterization of exopla…
SUPERSHARP - Segmented Unfolding Primary for Exoplanet Research via Spectroscopic High Angular Resolution Photography
Ian Parry, Didier Queloz, Grant Kennedy +20
We propose to search for biosignatures in the spectra of reflected light from about 100 Earth-sized planets that are already known to be orbiting in their habitable zones (HZ). For…
