摘要: We present the results of CO (J = 3 – 2) and 1 0) mapping observations toward active cluster-forming clump, L1688, in ρ Ophiuchi molecular cloud. From data cubes, we identify five outflows, whose driving sources are VLA 1623, EL 32, LFAM 26, 29, IRS 44. Among identified most luminous outflow is one from prototypical Class 0 source, 1623. also discover that 32 located Oph B2 region has very extended blueshifted redshifted lobes with wide opening angles. This massive largest momentum among outflows map. estimate total energy injection rate due to by previous studies be about 0.2 L ☉, larger than or at least comparable turbulence dissipation [≈(0.03 0.1)L ☉]. Therefore, conclude protostellar likely play a significant role replenishing supersonic this clump.
