Is the mechanism of solar flares on red dwarfs and brown dwarfs the same as that on the Sun?
The Sun has solar flares that are caused when there is a magnetic reconnection in the Sun's atmosphere, causing a loop of magnetic field to be ejected at high energy, along with a large number of ...

Strength of the relationship between very large solar flares, coronal mass ejections, and solar proton events?
In the years 774-775 and 993-994, there were large peaks in Earth's atmospheric radiocarbon (14C) concentration. While the cause was initially disputed, Mekhaldi et al.'s 2015 study of annually ...

Solar flares/CME dangers to life?
I know a repeat of the 1859 Carrington Event (coronal mass ejection) would pose a severe risk to power grids and telecommunication networks but wouldn't pose an immediate threat to life.
If a large ...
