Researchers from NAOC employed two methods of calculating magnetic helicity on the Sun to explore the energy and topology transportation from solar interior to the corona. And this study has been published in The Astrophysical Journal.

Brown dwarfs can maintain kilogauss magnetic fields and produce flaring radio emissions, similar to aurora on magnetized planets in solar system. This paper carried out a statistical analysis of radio-flaring brown dwarf population, which help quantify the potential of finding such objects in FAST drift-scan survey. The survey is expected to increase the number of flaring brown dwarfs by almost one order of magnitude, and improve our understanding of this flaring emission at low frequency.
