Abstract (from CDS):
We present the Hα imaging data and flux measurements for 30 dwarf galaxies in the Local Volume. The Hα fluxes are used to derive the galaxy star-formation rate (SFR). The sample of observed galaxies is characterized by the following parameters: a median distance of 7.5Mpc, median blue absolute magnitude of -14.8mag and median SFR of -2.0dex. Two dSph members of the Local Group, Cetus and Leo IV, do not show signs of star formation, with rates of -5.4 and -7.0dex, respectively. The BCD galaxy ESO 553-46 has one of the highest specific SFRs among the Local Volume galaxies.
