A molecular-line study of the interstellar bullet engine IRAS 05506+2414

open access: yes, 2017
We present interferometric and single-dish molecular line observations of the interstellar bullet-outflow source IRAS 05506+2414, whose wide-angle bullet spray is similar to the Orion BN/KL explosive outflow and likely arises from an entirely different ...
