Scientific paper

We present 3'' (~400 AU) OVRO and IRAM interferometer observations at λ=3.0 mm and 1.3 mm of L1527, one of the closest protostellar collapse candidates, We imaged high excitation lines of H2CO and HC3N in an effort to probe the highest densities, temperatures and infall velocities close to the L1527 protostar. The integrated intensity maps show an elongated structure of major axis size 20'' oriented perpendicular to the bipolar outflow axis. Spectral signatures associated with infall persist to the smallest scales observed.
