AN INTUITIVE PARAMETRIC MODEL FOR MHD TURBULENCE AND SIMPLE APPLICATIONS TO ASTROPHYSICS

Salle de conférence Roche + Visio

Jean Baptiste Durrive - IRAP An analytical model for 3D incompressible turbulence was recently introduced in the hydrodynamics community which, with only a few parameters, shares many properties of experimental and numerical turbulence. In our work, we extend this approach to compressible and magnetized fluids, in view of modeling astrophysical environments. Our model constitutes a […]

THE CHALLENGE OF ROBUST ORBITAL MEASUREMENTS OF DIRECTLY-IMAGED EXOPLANETS AND BROWN DWARFS

Visioconference

Orbital monitoring of circumstellar systems is complementary to the spectrometry of the atmospheres as it allows for analyzing their architecture, dynamical state and evolution, and formation. It is required to derive the orbital parameters and robust model-independent mass measurements. Measuring these parameters for imaged exoplanets and brown dwarfs can lead to degeneracies and biases because […]

L’Astronomie pour l’Education dans l’espace francophone

L'objectif du colloque « AstroEdu-Fr » est de partager des expériences de recherche, enseignement, formation et/ou de médiation pour promouvoir l’utilisation de l’astronomie pour l’éducation. Il a pour ambition d’aboutir à un « livre blanc » sur l’utilisation de l’astronomie pour l’éducation au sein de l’espace francophone.
