Spectral Index as a Function of Mass Accretion Rate in Black Hole Sources. Monte-Carlo Simulations and an Analytical Description
black hole physics accretion disks radiation mechanisms
2010/11/16
We present herein a theoretical study of correlations between spectral indexes of X-ray emergent spectra and mass accretion rate (m˙ ) in black hole (BH) sources,which provide a definitive signature f...
Numerical Simulations of Kinetic Alf ´v en Waves to Study Spectral Index in Solar Wind Turbulence and Particle Heating
Kinetic Alfv´ en wave filamentation solar wind spectral index chaotic structure
2010/9/16
We present numerical simulations of the modified nonlinear Schr¨odinger equation satisfied by kinetic Alfv´en waves (KAWs) leading to the formation of magnetic filaments at different times. The ...
