Abstract
In this paper we use previously determined H? 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? flux and, for the first time,
we take into account optical emission from supernova remnants (SNRs) as a
possible source of contamination of H? 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? flux in our calculation of SFR.
