Giant flare detected on a pre-main sequence M star

Using the Next Generation Transit Survey (NGTS), astronomers have identified an energetic flare displaying quasi-periodic pulsations on the pre-main sequence M star NGTS J121939.5-355557. The newly detected flare is one of the most energetic flares seen on an M-type star to date. The finding is reported in a paper published November 5 on arXiv.org.
