%0 Journal Article %T Star formation rate in Holmberg IX dwarf galaxy %A An£¿eli£¿ M.M. %J Serbian Astronomical Journal %D 2011 %I Astronomical Observatory, Department of Astronomy, Belgrade %R 10.2298/saj1183071a %X In this paper we use previously determined H¦Á fluxes for dwarf galaxy Holmberg IX (Arbutina et al. 2009) to calculate star formation rate (SFR) in this galaxy. We discuss possible contaminations of H¦Á flux and, for the first time, we take into account optical emission from supernova remnants (SNRs) as a possible source of contamination of H¦Á flux. Derived SFR for Holmberg IX is 3:4 x 10-4M.yr-1. Our value is lower then in previous studies, due to luminous shock-heated source M&H 9-10, possible hypernova remnant, which we excluded from the total H¦Á flux in our calculation of SFR. %K galaxies: dwarf %K galaxies: ISM %K HII regions %K ISM: supernova remnants %K stars: formation %U http://www.doiserbia.nb.rs/img/doi/1450-698X/2011/1450-698X1183071A.pdf
