Rapid acceleration of electrons in the magnetosphere by fast-mode MHD waves
Danny Summers, Chunyu Ma
During major megnetic storms, enhanced flux of relativistic electrons in the inner magnetosphere have been observed to correleated with ULF waves. The enhancements can take place o…
A Model for Generating Relativistic Electrons in the Earth's Inner Magnetosphere Based on Gyroresonant Wave-Particle Interactions
Danny Summers, Chun-yu Ma
During the recovery phase of a magnetic storm, fluxes of relativistic ( MeV) electrons in the inner magnetosphere () increase to beyond pre-storm levels, reaching…
Formation of Power-law Energy Spectra in Space Plasmas by Stochastic Acceleration due to Whistler-Mode Waves
Chun-yu Ma, Danny Summers
A non-relativistic Fokker-Planck equation for the electron distribution function is formulated incorporating the effects of stochastic acceleration by whistler-mode waves and Coulo…
Positron-Cyclotron Maser for the Core Emissions from Pulsars
Chun-yu Ma, Ding-yi Mao, De-yu Wang +1
We use the cyclotron-maser theory to explain the core emission from the magnetosphere of pulsars. As a kind of direct and efficient maser type of emission, it can give rise to esca…
On the dynamo driven accretion disks
Chun-yu Ma, Peter L Biermann
We add the effect in the dynamo driven accretion disk model proposed by Tout & Pringle (1992), i.e., a dynamo model depends on the physical processes such as Parker instabilit…
