A Starless Core that Isnt: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope


الملخص بالإنكليزية

We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope shows 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.
