Abstract

Arcsecond-resolution spectral observations toward the protobinary system IRAS 16293-2422 at 344 and 354 GHz were conducted using the Submillimeter Array. Several complex organic molecules, such as CH₃OH and HCOOCH ₃, were detected and mapped. Together with the rich organic inventory revealed, it clearly indicates the existence of two, rather than one, compact hot molecular cores (≲400 AU in radius) associated with each of the protobinary components identified by their dust continuum emission in the inner star-forming core.
