Canes Venatici I cloud of galaxies seen in the Hα line.

KAISIN S.S. and KARACHENTSEV I.D.

Abstract (from CDS):

We present results of Hα imaging for 42 galaxies in the nearby low-density cloud Canes Venatici I, populated mainly by late-type objects. Estimates of the Hα flux and integrated star formation rate (SFR) are now available for all 78 known members of this scattered system, spanning a large range in luminosity, surface brightness, HI content and SFR. Distributions of the CVnI galaxies versus their SFR, blue absolute magnitude and total hydrogen mass, are given in comparison with those for a population of the nearby virialized group around M81. We found no essential correlation between star formation activity in a galaxy and its density environment. The bulk of CVnI galaxies had enough time to generate their baryon mass with the observed SFR. Most of them also possess a supply of gas that is sufficient to maintain their observed SFRs during the next Hubble time.
