The SPHERE data center: a reference for high contrast imaging processing
Ph. Delorme, N. Meunier, D. Albert +19
The objective of the SPHERE Data Center is to optimize the scientific return of SPHERE at the VLT, by providing optimized reduction procedures, services to users and publicly avail…
The Scuti pulsations of Pictoris as observed by ASTEP from Antarctica
D. Mékarnia, E. Chapellier, T. Guillot +13
The Antartica Search for Transiting Extrasolar Planets (ASTEP), an automatized 400 mm telescope located at Concordia station in Antarctica, monitored beta Pictoris continuously to…
Variability in stellar granulation and convective blueshift with spectral type and magnetic activity. II. From young to old main-sequence K-G-F stars
Nadège Meunier, Lucile Mignon, Anne-Marie Lagrange
The inhibition of small-scale convection in the Sun dominates the long-term radial velocity (RV) variability: it therefore has a critical effect on light exoplanet detectability us…
Investigation of the inner structures around HD169142 with VLT/SPHERE
R. Ligi, A. Vigan, R. Gratton +47
We present observations of the Herbig Ae star HD169142 with VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) ( and bands) and the Integral Fie…
In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B
P. Delorme, T. Schmidt, M. Bonnefoy +47
The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties o…
A new method of correcting radial velocity time series for inhomogeneous convection
N. Meunier, A. -M. Lagrange, S. Borgniet
Magnetic activity strongly impacts stellar RVs and the search for small planets. We showed previously that in the solar case it induces RV variations with an amplitude over the cyc…
