A Natural Laboratory for Astrochemistry: The Variable Protostar B335
Emission lines from complex organic molecules in B335 were observed in four epochs, spanning a luminosity burst of about 10 yr duration. The emission lines increased dramatically in intensity as the luminosity increased, but they have decreased only slightly as the luminosity has decreased. This beh...

| description | Emission lines from complex organic molecules in B335 were observed in four epochs, spanning a luminosity burst of about 10 yr duration. The emission lines increased dramatically in intensity as the luminosity increased, but they have decreased only slightly as the luminosity has decreased. This behavior agrees with expectations of rapid sublimation as the dust temperature increases, and of slower freeze-out after the dust temperature drops. Further monitoring of this source, along with detailed chemical models, will exploit this natural laboratory for astrochemistry. |
