[V347 Aur, a #lighthouse in the galaxy] Some stars, like V347 Aurigae, vary greatly in #brightness over short time scales. But why? How? The answer with #SPIRou, the infrared spectropolarimeter installed on the #CFHT : https://www.irap.omp.eu/en/2024/10/spirou-decodes-the-bursts-of-a-protostar/

Around the #protostar V347 Aurigae orbits a brown dwarf of 30 Jupiter masses. Its elliptical trajectory invites the two bodies to periodically move towards and away from each other, generating #instabilities in the #disc of matter that envelops and feeds the nascent binary system. The fall of #matter onto the protostar results in a temporary increase in its luminosity by a factor of 100. Periodic light bursts captured by the SPIRou instrument.

Annual European Rheology Conference 2024 takes place at the University of #Leeds, UK from 9th-12th April 2024.

Moved to #Astrodon, so I guess that an #introduction is in order! 😄

Hello there! I'm a #CNRS researcher at the Observatoire de la Côte d'Azur. My work concerns #plasmas, #turbulence, #magneticfields, #instabilities, and its application range from the turbulent heating of the #solarwind and its interaction with planetary #magnetospheres, to the transport of #cosmicrays in the Galaxy. 🤓

Besides work, I love #taekwondo, I really enjoy #seaside and #beach, and I'm a big #nerd too, of course! 😎
