The Young Suns Exoplanet Survey: Detection of a wide-orbit planetary-mass companion to a solar-type Sco-Cen member

The Young Suns Exoplanet Survey consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus association with an average age of 15 ensuremath± 3 Myr. We report the detection of …

VizieR Online Data Catalog: A planetary-mass companion to a solar-type star (Bohn+, 2020)

Fits images corresponding to the imagery presented in the paper. The data are obtained with VLT/SPHERE/IRDIS. The data reduction is performed with version 0.8.1 of PynPoint. We detect a co-moving companion around The solar-type Sco-Cen member TYC …

VizieR Online Data Catalog: Discovery of a resolved disk around Wray 15-788 (Bohn+, 2019)

Fits images corresponding to the imagery presented in the paper. The data are obtained with VLT/SPHERE/IRDIS. The data reduction is performed with the latest version of PynPoint. In both total and polarized intensity we resolve a disk around the …

Multiple rings in the transition disk and companion candidates around RX J1615.3-3255. High contrast imaging with VLT/SPHERE

Context. The effects of a planet sculpting the disk from which it formed are most likely to be found in disks that are in transition between being classical protoplanetary and debris disks. Recent direct imaging of transition disks has revealed …

Magnetically Controlled Accretion on the Classical T Tauri Stars GQ Lupi and TW Hydrae

We present high spectral resolution (R ensuremath≈ 108, 000) Stokes V polarimetry of the classical T Tauri stars (CTTSs) GQ Lup and TW Hya obtained with the polarimetric upgrade to the HARPS spectrometer on the ESO 3.6 m telescope. We present data on …

The effects of disk and dust structure on observed polarimetric images of protoplanetary disks

Context. Imaging polarimetry is a powerful tool for imaging faint circumstellar material. It is a rapidly developing field with great promise for diagnostics of both the large-scale structures and the small-scale details of the scattering particles. …
