Structures in the protoplanetary disk of HD142527 seen in polarized scattered light
Henning Avenhaus, Sascha P. Quanz, Hans Martin Schmid +4
We present H- and Ks-band polarized differential images (PDI) of the Herbig Ae/Be star HD142527, revealing its optically thick outer disk and the nearly empty gap. The very small i…
Small vs large dust grains in transitional disks: do different cavity sizes indicate a planet?
Antonio Garufi, Sascha P Quanz, Henning Avenhaus +7
Transitional disks represent a short stage of the evolution of circumstellar material. Studies of dust grains in these objects can provide pivotal information on the mechanisms of…
Prospects of detecting the polarimetric signature of the Earth-mass planet alpha Centauri B b with SPHERE / ZIMPOL
Julien Milli, David Mouillet, Dimitri Mawet +5
Over the past five years, radial-velocity and transit techniques have revealed a new population of Earth-like planets with masses of a few Earth masses. Their very close orbit arou…
Measurement of the earthshine polarization in the B, V, R, and I band as function of phase
Andreas Bazzon, Hans Martin Schmid, Daniel Gisler
The characterization of the polarimetric properties of the planet Earth is important for the interpretation of expected observations and the planning of future instruments. We pres…
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…
Gaps in the HD169142 protoplanetary disk revealed by polarimetric imaging: Signs of ongoing planet formation?
Sascha P. Quanz, Henning Avenhaus, Esther Buenzli +3
We present H-band VLT/NACO polarized light images of the Herbig Ae/Be star HD169142 probing its protoplanetary disk as close as ~0.1" to the star. Our images trace the face-on disk…
