A "starless" core that isn't: Detection of a source in the L1014 dense core with the Spitzer Space Telescope
Research output: Contribution to journal › Journal article › Research › peer-review
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope show the presence of an embedded source. We propose a model for this source that includes a cold core, heated by the interstellar radiation field, and a low-luminosity internal source. The low luminosity of the internal source suggests a substellar object. If L1014 is representative, other "starless" cores may turn out to harbor central sources.
