Discovery of thermal radio recombination line emission towards the high-mass protostar IRAS18162-2048
The physical conditions within the innermost few tens of astronomical units of high-mass protostars (M_*>8 M_⊙) remain largely unexplored. At these scales, ionised emission can trace photoionised gas, accretion disks, or the base of protostellar jets. We search for ionised emission in the form of radio recombination li...
