Multiple molecular outflows and fragmentation in the IRDC core G34.43+00.24 MM1

The fragmentation of a molecular cloud that leads to the formation high-mass stars occurs on hierarchy different spatial scales. large clouds harbour massive clumps with cores embedded in them. these may determine initial mass function and masses final stars. Therefore, studying processes is crucial understand how form. hot core G34-MM1, IRDC G34.34+00.24 located at distance 3.6 kpc, promising object study both outflow processes. Using data 93 334 GHz obtained from Atacama Large Millimeter Array (ALMA) database we studied G34-MM1 great detail. angular resolution allowed us resolve structures about 0.014 pc ($\sim$2900 au). We found evidence towards two dust condensation MM1-A (about 0.06 size) harbours three subcores candidates (SC1 through SC3) detected $^{12}$CO J=3-2 emission, typical sizes 0.02 pc. From HCO$^+$ J=1-0 identify, better than previous observations, perpendicular outflows arising MM1-A. suggest SC1 SC2, MM1-A, sources responsible main secondary outflow, respectively. Finally, radio continuum emission GHz, marginally another condensation, named MM1-E, which young, massive, energetic arises. scales, together presence multiple associated it, would support competitive accretion scenario.
