High Energy Solar Particle Events and Their Associated Coronal Mass Ejections
Manoharan, P. K.; Agalya, G.
Intense solar energetic particle (SEP) events data, associated with ground level enhancements (GLEs), occurred during 1989-2006 have been obtained from the spectrometers on board GOES spacecraft in the energy range 10-100MeV. The interplanetary effects of these events and their associated coronal mass ejections (CMEs) have been provided by the LAS…
Observations of X-Ray Flares and Associated MHD Oscillations in Star ξ Boo
Srivastava, A. K.; Pandey, J. C.
Using data from observations made with XMM-Newton, we present an X-ray analysis of two flares observed in ξ Boo. The flare loop parameters are derived using various loop models including state-of-the-art hydrodynamic flare model. The loop lengths derived for the flaring loop structure are found to be less than the stellar radius. The exponential d…
