Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The linearized Vlasov and Vlasov-Fokker-Planck equations in a uniform magnetic field
均匀磁场 线性化 Vlasov Vlasov-Foker-Planck方程
2023/5/17
We study the linearized Vlasov equations and the linearized Vlasov-Fokker-Planck equations in the weakly collisional limit in a uniform magnetic field. In both cases, we consider periodic confinement ...
When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space be...
May 29, 2007，Sound waves escaping the sun’s interior create fountains of hot gas that shape and power a thin region of the sun’s atmosphere which appears as a ruby red "ring of fire" around the moon d...
4 May 2007，Being the closest planet to the Sun, you might think Mercury would be the most likely rocky planet in the Solar System to have a molten core, but for the past three decades physicists have ...
