The ALMA Early Science View of FUor/EXor objects. II. The Very Wide Outflow Driven by HBC 494
D. Ruíz-Rodríguez, L. A. Cieza, J. P. Williams +10
We present Atacama Large Millimeter/sub-millimeter Array (ALMA) Cycle-2 observations of the HBC 494 molecular outflow and envelope. HBC 494 is an FU Ori-like object embedded in the…
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…
The ALMA Early Science view of FUor/EXor objects. I. Through the looking-glass of V2775 Ori
Alice Zurlo, Lucas A. Cieza, Jonathan P. Williams +11
As part of an ALMA survey to study the origin of episodic accretion in young eruptive variables, we have observed the circumstellar environment of the star V2775 Ori. This object i…
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…
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…
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…
Imaging the water-snow line during a protostellar outburst
Lucas A. Cieza, Simon Casassus, John Tobin +13
A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role…
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…
Constraining the mass of the planet(s) sculpting a disk cavity. The intriguing case of 2MASS J16042165-2130284
H. Canovas, A. Hardy, A. Zurlo +10
The large cavities observed in the dust and gas distributions of transition disks may be explained by planet-disk interactions. At ~145 pc, 2MASS J16042165-2130284 (J1604) is a 5-1…
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…
