Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B
C. Lazzoni, A. Zurlo, S. Desidera +45
In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. In this paper, we focus our attention on substellar c…
K-Stacker, an algorithm to hack the orbital parameters of planets hidden in high-contrast imaging. First applications to VLT SPHERE multi-epoch observations
H. Le Coroller, M. Nowak, P. Delorme +40
Recent high-contrast imaging surveys, looking for planets in young, nearby systems showed evidence of a small number of giant planets at relatively large separation beyond typicall…
Searching for the near infrared counterpart of Proxima c using multi-epoch high contrast SPHERE data at VLT
R. Gratton, A. Zurlo, H. Le Coroller +43
Proxima Centauri is known to host an earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, the ex…
