ON SYSTEMATICS IN OB/H II COMPLEXES IN THE SPIRAL ARMS OF M 51
Abstract:Systematics in the location of brightest OB/H II complexes in the major spiral arms of M 51 is discussed with the use of recently published far-UV and Hα data. It is demonstrated that the objects occupy predominantly the areas around the corners of the polygonal arm pattern of this galaxy. This is treated as evidence that the physical conditions in these specific areas can enhance massive star formation. A possible gas dynamical explanation is suggested for the phenomenon.
