Coronal Elemental Abundances during A-class Solar Flares Observed by Chandrayaan-2 XSM
Lakshitha Nama, Biswajit Mondal, S Narendranath +1
The abundances of low First Ionisation Potential (FIP) elements are three to four times higher (FIP bias) in the closed loop active corona than in the photosphere, known as the FIP…
Role of small-scale impulsive events in heating the X-ray bright points of the quiet Sun
Biswajit Mondal, James A Klimchuk, Santosh V. Vadawale +6
Small-scale impulsive events, known as nanoflares, are thought to be one of the prime candidates that can keep the solar corona hot at its multi-million Kelvin temperature. Individ…
