Program: GN-2012B-Q-86

Based on numerical simulations of embedded newborn mutiple systems, we have identified extended phases during which a protostar born in a small triple system is ejected into distant highly eccentric orbits in the outskirts or even outside of its nascent cloud core. Such objects are dubbed orphans. We have identified a number of orphan candidates closely associated with sources having jets or pwerful mass loss. We propose to study these orphans spectroscopically using GNIRS in order to determine to what extent their circumstellar disks have been affected by the ejection events. This is a re-submission of a program that failed to be executed for two seasons despite being in Band 1.
