IRAS16293E revisited: a new understanding of a prestellar core in interaction with an outflow
2015
The study of prestellar cores starts with establishing their density and temperature structures. To explore the densest part, deu-terated species, N-bearing molecules, or dust are usually considered. Among prestellar cores, IRAS16293E is a rare case of a core being perturbed by the outflow of a nearby protostar (IRAS16293-2422 A/B). A part of the outflow hits the core and heats it, introducing a temperature gradient that makes the analysis difficult. It is only after having gathered observations from Spitzer, Herschel, SCUBA, MAMBO, and of various molecular lines from CSO, APEX, JCMT and IRAM that a clearer picture of this core has finally arisen.
