The complex chemistry of outflow cavity walls exposed: the case of low-mass protostars
Maria N. Drozdovskaya, Catherine Walsh, Ruud Visser +2
Complex organic molecules are ubiquitous companions of young low-mass protostars. Recent observations suggest that their emission stems, not only from the traditional hot corino, b…
Molecule sublimation as a tracer of protostellar accretion: Evidence for accretion bursts from high angular resolution C18O images
Jes K. Jorgensen, Ruud Visser, Jonathan P. Williams +1
The accretion histories of embedded protostars are an integral part of descriptions of their physical and chemical evolution. In particular, are the accretion rates smoothly declin…
Chemical tracers of episodic accretion in low-mass protostars
Ruud Visser, Edwin A. Bergin, Jes K. Jorgensen
Aims: Accretion rates in low-mass protostars can be highly variable in time. Each accretion burst is accompanied by a temporary increase in luminosity, heating up the circumstellar…
