Massivestar formation takes place in molecular hot cores which are theresult of the fragmentation of massive clumps. The infrared darkcloud G34.43+00.24,which exhibits a filamentary structure, is located at a distance ofabout 3.6 kpc. This cloud harbours nine molecular cores, named MM1through MM9, at different evolutionary stages. This work presents astudy of the internal structure of the core MM1 carried out with highangular resolution observations at 93 GHz obtained from the ALMAdatabase. The radio continuum emission shows signatures offragmentation of the core, and the HCO+ J=1-0 emission confirms, withthe better angular resolution at the present, the presence of twoperpendicular molecular outflows arising from MM1.p { margin-bottom: 0.25cm; line-height: 115% }
