Description
Very recently, gamma-ray emission detected by Fermi-LAT was reported from a star forming region NGC 2071. The high-energy radiation was claimed to be associated with occasional mega-flares thought to occur in T Tauri stars. The source, detected at energies $E \sim 100$\,GeV, appears to be transient, and was only detectable during the first two years of observation. In this work, we investigate the nature of the Fermi source, assuming that it was produced by particles accelerated in a protostar within NGC 2071. We discuss different scenarios capable of reproducing the detected peculiar spectral energy distribution and the time scale reported for the gamma-ray source.
