J. and the ngVLA Science Advisory Council||Series:||ASTRONOMICAL SOCIETY OF THE PACIFIC CONFERENCE SERIES||Number:||517||First Page:||309||Abstract:||In this contribution we explore the new science that a next generation Very Large Array (ngVLA) would be able to perform on the topics of the youngest HII regions and (proto)stellar jets. Free-free continuum and radio recombination line (RRL) emission are often the only way of peering into the dense envelopes surrounding (proto)stars of all masses, and trace their initial feedback in the form of 'radio jets', 'hypercompact HII regions', or photoevaporating, partially-ionized flows. Properly disentangling free-free from dust emission is also mandatory in studies of protoplanetary and accretion disks. Current VLA research has reached an impasse in which a population of faint ionized radio sources, probably corresponding to the above mentioned objects, is detected, but their nature is mostly unknown. The ngVLA would allow us to resolve the density structure and kinematics of such sources, revolutionizing our knowledge of star formation across the entire stellar-mass spectrum.||Conference Name:||Science with a Next Generation Very Large Array||URI:||http://hdl.handle.net/20.500.12386/28089||URL:||https://arxiv.org/pdf/1806.10225.pdf
