Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
D. Mesa, A. Zurlo, J. Milli +36
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Cen…
Three radial gaps in the disk of TW Hydrae imaged with SPHERE
Roy van Boekel, Thomas Henning, Jonathan Menu +24
We present scattered light images of the TW Hya disk performed with SPHERE in PDI mode at 0.63, 0.79, 1.24 and 1.62 micron. We also present H2/H3-band ADI observations. Three disti…
Scattered light mapping of protoplanetary disks
T. Stolker, C. Dominik, M. Min +3
High-contrast scattered light observations have revealed the surface morphology of several dozens of protoplanetary disks at optical and near-infrared wavelengths. Inclined disks o…
A cavity and further radial substructures in the disk around HD~97048
G. van der Plas, C. M. Wright, F. Ménard +9
Context: Gaps, cavities and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with…
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…
The SPHERE view of the planet-forming disk around HD100546
Antonio Garufi, Sascha P. Quanz, Hans Martin Schmid +39
We image with unprecedented spatial resolution and sensitivity disk features that could be potential signs of planet-disk interaction. Two companion candidates have been claimed in…
A lucky imaging multiplicity study of exoplanet host stars II
C. Ginski, M. Mugrauer, M. Seeliger +6
The vast majority of extrasolar planets are detected by indirect detection methods such as transit monitoring and radial velocity measurements. While these methods are very success…
Azimuthal asymmetries in the debris disk around HD61005
J. Olofsson, M. Samland, H. Avenhaus +30
Debris disks offer valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In the…
