Observations of the Quiet Sun during the Deepest Solar Minimum of the Past Century with Chandrayaan-2 XSM: Sub-A-class Microflares outside Active Regions

Autor: Tinkal Ladiya, Sushil Kumar, Arpit R. Patel, Shiv Kumar Goyal, Mahesh P Shanmugam, Anil Bhardwaj, P. Janardhan, Hitesh Kumar L. Adalja, N. P. S. Mithun, Neeraj Kumar Tiwari, Biswajit Mondal, Aveek Sarkar, Nishant Singh, Santosh V. Vadawale, Bhuwan Joshi

Publikováno v: The Astrophysical Journal Letters. 912:L13

Solar flares, with energies ranging over several orders of magnitude, result from impulsive release of energy due to magnetic reconnection in the corona. Barring a handful, almost all microflares observed in X-rays are associated with the solar activ

Publikováno v: The Astrophysical Journal Letters. 912:L12

Elements with low First Ionization Potential (FIP) are known to be three to four times more abundant in active region loops of the solar corona than in the photosphere. There have been observations suggesting that this observed "FIP bias" may be diff
