Abstract:
We present the case of VLA1623, a triple non-coeval protostellar system in ρ Ophiuchus, the prototype Class 0 object. Its envelope is complex on the large scale, breaking down on the small scale to reveal that each component of the system has a different structure. Using ALMA cycle 0 observations of VLA1623 and combining the observations with models, we analyze the envelope of each of VLA1623\'s components, searching for rotationally supported disks, attempting to unravel what is going on in this system and to address some of the questions of its formation.
