A HARPS RV search for planets around young nearby stars
A. Grandjean, A. -M. Lagrange, M. Keppler +9
Young nearby stars are good candidates in the search for planets with both radial velocity (RV) and direct imaging techniques. This, in turn, allows for the computation of the gian…
Shadowing and multiple rings in the protoplanetary disk of HD 139614
G. A. Muro-Arena, M. Benisty, C. Ginski +20
Shadows in scattered light images of protoplanetary disks are a common feature and support the presence of warps or misalignments between disk regions. These warps are possibly due…
VLT/SPHERE exploration of the young multiplanetary system PDS70
D. Mesa, M. Keppler, F. Cantalloube +51
Context. PDS 70 is a young (5.4 Myr), nearby (~113 pc) star hosting a known transition disk with a large gap. Recent observations with SPHERE and NACO in the near-infrared (NIR) al…
An Ideal Testbed for Planet-disk Interaction: Two Giant Protoplanets in Resonance Shaping the PDS 70 Protoplanetary Disk
Jaehan Bae, Zhaohuan Zhu, Clément Baruteau +7
While numerical simulations have been playing a key role in the studies of planet-disk interaction, testing numerical results against observations has been limited so far. With the…
A multi-wavelength study of the debris disc around 49 Cet
Nicole Pawellek, Attila Moór, Julien Milli +17
In a multi-wavelength study of thermal emission and scattered light images we analyse the dust properties and structure of the debris disc around the A1-type main sequence star 49~…
Submillimeter emission associated with candidate protoplanets
Andrea Isella, Myriam Benisty, Richard Teague +4
We present the discovery of a spatially unresolved source of sub-millimeter continuum emission ( m) associated with a young planet, PDS 70 c, recently detected in H em…
