Radial velocities: direct application of Pierre Connes' shift finding algorithm to Cross-Correlation Functions
Jean-Loup Bertaux, Anastasiia Ivanova, Rosine Lallement
Pipelines of state-of-the-art spectrographs dedicated to planet detection provide, for each exposure, series of Cross-Correlation Functions (CCFs) built with a Binary Mask (BM), an…
Improved precision of radial velocity measurements after correction for telluric absorption
A. Ivanova, R. Lallement, J. L. Bertaux
The detection of planets around other stars by the measurement of the stellar Radial Velocity (RV) variations benefits from improvements of dedicated spectrographs, allowing to ach…
Electron dynamics in small magnetospheres: insights from global fully-kinetic plasma simulations of planet Mercury
Federico Lavorenti, Pierre Henri, Francesco Califano +4
The planet Mercury possesses a small but highly dynamic magnetosphere in which the role and dynamics of electrons are still largely unknown. We aim at modeling the global dynamics…
Towards a 3D kinetic tomography of Taurus clouds: I -- Linking neutral potassium and dust
A. Ivanova, R. Lallement, J. L. Vergely +1
Results. We illustrate our profile-fitting technique and present the K\,{\sc i} velocity structure of the dense ISM along the paths to all targets. As a validation test of the dust…
The floatability of aerosols and waves damping on Titan's seas
Daniel Cordier, Nathalie Carrasco
Titan, Saturn's largest moon, has a dense atmosphere, together with lakes and seas of liquid hydrocarbons. These liquid bodies, which are in polar regions and up to several hundred…
Gaia Data Release 2: Processing the spectroscopic data
P. Sartoretti, D. Katz, M. Cropper +50
The Gaia Data Release 2 contains the 1st release of radial velocities complementing the kinematic data of a sample of about 7 million relatively bright, late-type stars. Aims: This…
