"WebIn most irregulars, star formation occurs within the galaxies' Holmberg radius and within three disk scale lengths ( Hunter & Elmegreen 2004 ). In contrast, in blue compact dwarf (BCD) galaxies the highest star formation rates are found, and star formation occurs mainly in the central regions (Hunter & Elmegreen).
