    Abstract

    We present the dust properties of a small sample of Virgo cluster dwarf galaxies drawn from the science demonstration phase data set of the Herschel Virgo Cluster Survey. These galaxies have low metallicities (7.8 <12 + log(O/H) <8.3) and star-formation rates 10-1 M yr-1. We measure the spectral energy distribution (SED) from 100 to 500 μm and derive dust temperatures and dust masses. The SEDs are fitted by a cool component of temperature T 20 K, implying dust masses around 105 M and dust-to-gas ratios mathcal D within the range 10-3-10 -2. The completion of the full survey will yield a larger set of galaxies, which will provide more stringent constraints on the dust content of star-forming dwarf galaxies. © ESO, 2010.
