Protostellar Outflows in L1340

Solar and Stellar Astrophysics 2016-12-14 v1

Abstract

We have searched the L1340 A, B, and C clouds for shocks from protostellar outflows using the H2_2 2.122 μ\mum near-IR line as a shock tracer. Substantial outflow activity has been found in each of the three regions of the cloud (L1340 A, L1340 B, & L1340 C). We find 42 distinct shock complexes (16 in L1340 A, 11 in L1340 B, and 15 in L1340 C). We were able to link 17 of those shock complexes in to 12 distinct outflows and identify candidate source stars for each. We examine the properties (AV_{V}, Tbol_{bol}, and Lbol_{bol}) of the source protostars and compare that to the properties of the general population of Class 0/I and flat SED protostars and find that there is an indication, albeit at low statistical significance, that the outflow driving protostars are drawn from a population with lower AV_{V}, higher Lbol_{bol}, and lower Tbol_{bol} than the general population of protostars.
