WebOct 12, 2024 · What are M-dwarf flares M-dwarf stars have strong magnetic fields and convective envelopes. The magnetic field lines are dragged around due to convective motion in the envelope. This magnetic activity can cause a sudden energy release through a mechanism known as magnetic reconnection. WebRed dwarfs are usually defined as being of spectral type M, although some definitions are wider (including also some or all K-type stars). Given their low energy output, red dwarfs are almost never naked-eye visible from Earth: the closest red dwarf to the Sun, Proxima Centauri, is nowhere near visual magnitude.
