Efficiency of massive star formation in grand design spirals
The present study estimates the efficiency ratio for massive star formation between the arms and the interarm disks of three grand design spirals. The estimate is based on H-alpha mapping observations of the H II regions in the galaxies. It is found that this efficiency ratio is 10 or more in the zones between the Lindblad resonances and the radius
