Star formation in the nuclear region of M82 due to recurrent explosions of the nucleus

  • Mamoru Saitō


The difference of spatial distributions between the O-type stars, supernovae and red giant stars found by Riekeet al. (1980) in the nuclear region of M82 can be interpreted if the star formation has been triggered by shock waves expanding from the nucleus with velocities of ∼ 100 km s−1 at ∼ 300 pc from the centre and if the explosions have recurrently occurred with time interval of about 2×106 yr. The recurrent formation of such giant compressed gas layer makes the formation rate of massive stars efficient.
