Webinaire ASNUM Clément Baruteau IRAP Hydrodynamical simulations of the reflex instability in protoplanetary discs Replay : https://astrotube.obspm.fr/w/r34pJg4Y6LwExtiZwREV8z Theoretical studies of protoplanetary discs have a long history, with many works on what instabilities may grow, and how they impact disc evolution and planet formation. By running long-term hydrodynamical simulations of disc-planet interactions, we have recently (and…

Webinaire ASNUM Jeff Wagg OCA The Era of Big Data in Radio Astronomy https://astrotube.obspm.fr/w/jUcNpvdsEdYyJSrh79G1ee Studying the faintest radio emitting objects in the Universe requires large single-dish telescopes, or multi-element interferometer arrays of either dishes or dipole antennas. The most ambitious of these is the international Square Kilometre Array Observatory (SKAO), consisting of two interferometers in…
