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…
Increasing the raw contrast of VLT/SPHERE with the dark hole technique. I. Simulations and validation on the internal source
Axel Potier, Raphaël Galicher, Pierre Baudoz +7
Context. Since 1995 and the first discovery of an exoplanet orbiting a main-sequence star, 4000 exoplanets have been discovered using several techniques. However, only a few of the…
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…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
Comparing focal plane wavefront control techniques:\\Numerical simulations and laboratory experiments
Axel Potier, Pierre Baudoz, Raphaël Galicher +2
Fewer than 1% of all exoplanets detected to date have been characterized on the basis of spectroscopic observations of their atmosphere. Unlike indirect methods, high-contrast imag…
