Abstract

Using the Submillimeter Array, we report the discovery of a compact low-mass bipolar molecular outflow from L1014-IRS and confirm its association with the L1014 dense core at 200 pc. Consequently, L1014-IRS is the lowest luminosity ( L ~ 0.09 L ☉ ), and perhaps the lowest mass, source known to be driving a bipolar molecular outflow, which is one of the smallest known in size (~500 AU), mass (<10 -4 M ☉ ), and energetics (e.g., with a force <10 -7 M ☉ km s -1 yr -1 ).
