Magnetic pulsations (Earth 🌍)

Magnetic pulsations are extremely low frequency disturbances in the Earth's magnetosphere driven by its interactions with the solar wind. These variations in the planet's magnetic field can oscillate for multiple hours when a solar wind driving force strikes a resonance. This is a form of Kelvin–Helmholtz instability. The intensity...

[#ActuScience @IRAP ] A young IRAP PhD student formulates a new #theoretical model of the giant #magnetospheres of the planets #Jupiter and #Saturn: "By considering only the global motion of the #plasma (coming from the moons #Io and #Enceladus), it is possible to understand it simply as... a competition between various rotation resistances!"

[@IRAP #Seminar] this Thursday at 11am. Benjamin Crinquant, a young researcher at IRAP, will present the progress we have made in our knowledge of #BlackHoles: from the observations carried out by the #GRAVITY and #EventHorizonTelescope collaborations to the most recent models of the #magnetospheres and #coronae of black holes.

[#Séminaire @IRAP] ce jeudi à 11h. Benjamin Crinquant, jeune chercheur à l'IRAP, présentera l'état de nos connaissances actuelles sur les #TrousNoirs : des observations menées par les collaborations #GRAVITY et #EventHorizonTelescope aux modélisations les plus récentes des #magnétosphères et des #couronnes des trous noirs.

Magnetic Field Draping in Induced #Magnetospheres: Evidence from the #MAVEN Mission to #Mars: https://arxiv.org/abs/2308.02720 -> "We conclude with an updated understanding of induced magnetospheres which details dayside draping for multiple directions of the incoming IMF and discuss the repercussions of this draping for magnetotail morphology."
