RefPlanets: Search for reflected light from extra-solar planets with SPHERE/ZIMPOL
S. Hunziker, H. M. Schmid, D. Mouillet +55
RefPlanets is a guaranteed time observation (GTO) programme that uses the Zurich IMaging POLarimeter (ZIMPOL) of SPHERE/VLT for a blind search for exoplanets in wavelengths from 60…
HD 117214 debris disk: scattered-light images and constraints on the presence of planets
N. Engler, C. Lazzoni, R. Gratton +34
We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…
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…
Investigating the nature of the extended structure around the Herbig star RCrA using integral field and high-resolution spectroscopy
E. Rigliaco, R. Gratton, D. Mesa +24
We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
The SPHERE view of the jet and the envelope of RY Tau
A. Garufi, L. Podio, F. Bacciotti +40
Jets are rarely associated with pre-main-sequence intermediate-mass stars. Optical and near-IR observations of jet-driving sources are often hindered by the presence of a natal env…
ISPY -- NaCo Imaging Survey for Planets around Young stars. Discovery of an M dwarf in the gap between HD 193571 and its debris ring
Arianna Musso Barcucci, Ralf Launhardt, Grant M. Kennedy +19
Context. The interaction between low-mass companions and the debris discs they reside in is still not fully understood. A debris disc can evolve due to self-stirring, a process in…
Determining mass limits around HD163296 through SPHERE direct imaging data
D. Mesa, M. Langlois, A. Garufi +33
HD163296 is a Herbig Ae/Be star known to host a protoplanetary disk with a ringed structure. To explain the disk features, previous works proposed the presence of planets embedded…
Two cold belts in the debris disk around the G-type star NZ Lup
A. Boccaletti, P. Thébault, N. Pawellek +36
Planetary systems hold the imprint of the formation and of the evolution of planets especially at young ages, and in particular at the stage when the gas has dissipated leaving mos…
The CORALIE survey for southern extrasolar planets XVIII. Three new massive planets and two low mass brown dwarfs at separation larger than 5 AU
E. L. Rickman, D. Ségransan, M. Marmier +36
Context. Since 1998, a planet-search around main sequence stars within 50~pc in the southern hemisphere has been carried out with the CORALIE spectrograph at La Silla Observatory.…
Hint of curvature in the orbital motion of the exoplanet 51 Eridani b using 3 years of VLT/SPHERE monitoring
A. -L. Maire, L. Rodet, F. Cantalloube +49
Context. The 51 Eridani system harbors a complex architecture with its primary star forming a hierarchical system with the binary GJ 3305AB at a projected separation of 2000 au, a…
ISPY - the NaCo Imaging Survey for Planets around Young stars: A young companion candidate embedded in the R CrA cloud
G. Cugno, S. P. Quanz, R. Launhardt +13
Within the NaCo-ISPY exoplanet imaging program, we aim at detecting and characterizing the population of low-mass companions at wide separations (10AU), focusing in partic…
Exploring the RCrA environment with SPHERE: Discovery of a new stellar companion
D. Mesa, M. Bonnefoy, R. Gratton +39
Aims. R Coronae Australis (R CrA) is the brightest star of the Coronet nebula of the Corona Australis (CrA) star forming region. It has very red colors, probably due to dust absorp…
