We investigate 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 (HeViCS). These galaxies have low metallicities ( 7.8<12+log(O/H)<8.37.8<12+log(O/H)<8.3 ) and star formation rates ≲≲ 0.1 M⊙ yr−1. We measure the spectral energy distribution (SED) from 100 to 500 μm and derive dust temperatures and masses. The SEDs are fitted by a cool component with T≲20T≲20 K, implying dust masses around 105 M⊙ and dust-to-gas ratios ( DD ) within the range 10−3–10−2
