The mass of Beta Pictoris c from Beta Pictoris b orbital motion
S. Lacour, J. J. Wang, L. Rodet +96
We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…
Unveiling wide-orbit companions to K-type stars in Sco-Cen with Gaia EDR3
Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +12
Abbreviated. We aim to identify new low-mass companions to young stars using the astrometric measurements provided by the Gaia space mission and complementary VLT/SPHERE data. We i…
A multiwavelength analysis of the spiral arms in the protoplanetary disk around WaOph 6
S. B. Brown-Sevilla, M. Keppler, M. Barraza-Alfaro +23
[Full abstract in the paper] In recent years, protoplanetary disks with spiral structures have been detected in scattered light, millimeter continuum, and CO gas emission. The mech…
Revealing asymmetrical dust distribution in the inner regions of HD 141569
Garima Singh, Trisha Bhowmik, Anthony Boccaletti +42
We obtained polarimetric differential imaging of a gas-rich debris disk around HD 141569A with SPHERE in the H-band to compare the scattering properties of the innermost ring at 44…
Perturbers: SPHERE detection limits to planetary-mass companions in protoplanetary disks
R. Asensio-Torres, Th. Henning, F. Cantalloube +25
The detection of a wide range of substructures such as rings, cavities and spirals has become a common outcome of high spatial resolution imaging of protoplanetary disks, both in t…
The SPHERE infrared survey for exoplanets (SHINE)- I Sample definition and target characterization
S. Desidera, G. Chauvin, M. Bonavita +105
Large surveys with new-generation high-contrast imaging instruments are needed to derive the frequency and properties of exoplanet populations with separations from 5 to 300…
