A "Starless" Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/183685We 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.7 pages, To appear in the ApJS Spitzer Special EditionAstrophysicsA "Starless" Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescopetext
