The H α Galaxy Survey ⋆ V . The star formation history of late-type galaxies

Abstract

Aims. This study of 117 low-redshift Im and Sm galaxies investigates the star formation rates of late-type galaxies, to determine whether they are quasi-continuous or dominated by bursts with quiescent interludes. Methods. We analyse the distribution of star formation timescales (stellar masses/star formation rates) for the entire sample, and of gas… (More)
