SPHERE/SHINE reveals concentric rings in the debris disk of HIP 73145
M. Feldt, J. Olofsson, A. Boccaletti +22
The debris disk of HIP73145 has been detected in scattered light in the near-IR, and at far-IR wavelengths before, but no substructure has been seen so far. Detection of such subst…
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…
Shadows and spirals in the protoplanetary disk HD 100453
M. Benisty, T. Stolker, A. Pohl +46
Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form. We observed and spatially resolv…
Multiple rings in the transition disk and companion candidates around RXJ1615.3-3255. High contrast imaging with VLT/SPHERE
J. de Boer, G. Salter, M. Benisty +36
We search for signs of ongoing planet-disk interaction and study the distribution of small grains at the surface of the transition disk around RXJ1615.3-3255 (RX J1615). We observe…
H-activity and ages for stars in the SARG survey
E. Sissa, R. Gratton, S. Desidera +7
Stellar activity influences radial velocity (RV) measurements and can also mimic the presence of orbiting planets. As part of the search for planets around the components of wide b…
Resolving the planet-hosting inner regions of the LkCa 15 disk
C. Thalmann, M. Janson, A. Garufi +28
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is…
Sub-0.1" optical imaging of the Z CMa jets with SPHERE/ZIMPOL
S. Antoniucci, L. Podio, B. Nisini +15
Crucial information on the mass accretion-ejection in young stars can be obtained from high spatial resolution images of jets in sources with recurrent accretion outbursts. Using t…
Characterizing HR3549B using SPHERE
D. Mesa, A. Vigan, V. D'Orazi +28
Aims. In this work, we characterize the low mass companion of the A0 field star HR3549. Methods. We observed HR3549AB in imaging mode with the the NIR branch (IFS and IRDIS) of SPH…
Discovery of concentric broken rings at sub-arcsec separations in the HD 141569A gas-rich, debris disk with VLT/SPHERE
C. Perrot, A. Boccaletti, E. Pantin +45
Transition disks correspond to a short stage between the young protoplanetary phase and older debris phase. Along this evolutionary sequence, the gas component disappears leaving r…
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…
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…
