Journal ArticleDOI
Using the Sun to estimate Earth-like planets detection capabilities - I. Impact of cold spots
TL;DR: In this paper, the photometric contribution of spots and plages to the radial velocity (RV) signal partially balance each other out, so that the residual signal is comparable to the spot signal.
Journal ArticleDOI
Astrometric and photometric accuracies in high contrast imaging : The SPHERE speckle calibration tool (SpeCal)
R. Galicher,Anthony Boccaletti,Dino Mesa,Philippe Delorme,Raffaele Gratton,Maud Langlois,A-M. Lagrange,Anne-Lise Maire,H. Le Coroller,Gael Chauvin,Beth Biller,Faustine Cantalloube,Markus Janson,Eric Lagadec,N. Meunier,Arthur Vigan,Janis Hagelberg,Mickael Bonnefoy,Alice Zurlo,S. Rocha,D. Maurel,Marc Jaquet,T. Buey,L.

TL;DR: The SPHERE consortium developed a dedicated piece of software to process the data as mentioned in this paper, which corrects for instrumental artifacts and uses the speckle calibration tool to minimize the stellar light halo that prevents us from detecting faint sources like exoplanets or circumstellar disks.
Journal ArticleDOI
Reconstructing the solar integrated radial velocity using MDI/SOHO
TL;DR: In this paper, the authors used Dopplergrams and magnetograms obtained by MDI/SOHO over one solar cycle to reconstruct the solar integrated radial velocity in the Ni line 6768 A.
Journal ArticleDOI

TL;DR: The Nearby Earth Astrometric Telescope (NEAT) as discussed by the authors is designed to carry out space-borne extremely high-precision measurements at the 0.05 mu as (1 sigma) accuracy level, sufficient to detect dynamical effects due to orbiting planets of mass even lower than Earth's around the nearest stars.
Journal ArticleDOI
Using the Sun to estimate Earth-like planets detection capabilities IV. Correcting for the convective component
N. Meunier,A-M. Lagrange +1 more
TL;DR: In this paper, the authors investigated the impact of stellar activity on the detectability of an Earth-mass planet in the habitable zone of the Sun as seen edge-on from a neighbour star in several typical cases.
