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…
Optimized Principal Component Analysis on Coronagraphic Images of the Fomalhaut System
T. Meshkat, M. Kenworthy, S. P. Quanz +1
We present the results of a study to optimize the principal component analysis (PCA) algorithm for planet detection, a new algorithm complementing ADI and LOCI for increasing the c…
Confirmation of the planet around HD 95086 by direct imaging
J. Rameau, G. Chauvin, A. -M. Lagrange +8
VLT/NaCo angular differential imaging at L' (3.8 microns) revealed a probable giant planet comoving with the young and early-type HD 95086 also known to harbor an extended debris d…
Multiple spiral patterns in the transitional disk of HD 100546
A. Boccaletti, E. Pantin, A. -M. Lagrange +3
Protoplanetary disks around young stars harbor many structures related to planetary formation. Of particular interest, spiral patterns were discovered among several of these disks…
On the frequency of planetary systems around G-dwarfs
Richard J. Parker, Sascha P. Quanz
We determine the fraction of G-dwarf stars that could host stable planetary systems based on the observed properties of binaries in the Galactic field, and in various postulated pr…
