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…
A medium-resolution spectrum of the exoplanet HIP 65426 b
Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +18
Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detectio…
Activity time series of old stars from late F to early K. V. Effect on exoplanet detectability with high-precision astrometry
N. Meunier, A. -M. Lagrange, S. Borgniet
Stellar activity strongly affects and may prevent the detection of Earth-mass planets in the habitable zone of solar-type stars with radial velocity technics. Astrometry is in prin…
Direct confirmation of the radial-velocity planet Pic c
M. Nowak, S. Lacour, A. -M. Lagrange +90
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
The effects of granulation and supergranulation on Earth-mass planet detectability in the habitable zone around F6-K4 stars
N. Meunier, A. M. Lagrange
The detectability of exoplanets and the determination of their projected mass in radial velocity are affected by stellar magnetic activity and photospheric dynamics. The effect of…
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…
