A very low-luminosity ( 0.1 Lo) embedded infrared source was discovered by Spitzer in the L1521F dense cloud core, falling within the region surveyed by the Taurus Spitzer Survey. The low-luminosity suggests the object is substellar, and its similarity to class 0 sources suggests it is extremely young. We investigate the dust temperature and density structure in the L1521F cloud core through a comparison of Spitzer MIPS 160 um and IRAS 100 um data. We compare the effects of L1521F IRS on its environment to those of nearby class 0/I protostars. We also present HCN(3-2) and C18O(2-1) JCMT observations of the cloud core. The results are discussed in the context of theoretical ideas for the very early phases of star formation.
