Revealing Efficient Dust-Formation at Low Metallicity in Extragalactic Carbon-Rich Wolf-Rayet Binaries

Ryan M. Lau, Matthew J. Hankins, Mansi M. Kasliwal +6

We present Spitzer/IRAC observations of dust formation from six extragalactic carbon-rich Wolf-Rayet (WC) binary candidates in low-metallicity (Z $\lesssim 0.65$ Z${}_{\odot }$) environm…
