Water in Low-Mass Star-Forming Regions with Herschel: The Link Between Water Gas and Ice in Protostellar Envelopes
M. Schmalzl, R. Visser, C. Walsh +4
Aims: Our aim is to determine the critical parameters in water chemistry and the contribution of water to the oxygen budget by observing and modelling water gas and ice for a sampl…
Methanol Along the Path from Envelope to Protoplanetary Disc
Maria N. Drozdovskaya, Catherine Walsh, Ruud Visser +2
Interstellar methanol is considered to be a parent species of larger, more complex organic molecules. A physicochemical simulation of infalling parcels of matter is performed for a…
Water in star-forming regions with Herschel (WISH) V. The physical conditions in low-mass protostellar outflows revealed by multi-transition water observations
J. C. Mottram, L. E. Kristensen, E. F. van Dishoeck +17
Context: Outflows are an important part of the star formation process as both the result of ongoing active accretion and one of the main sources of mechanical feedback on small sca…
ALMA observations of the kinematics and chemistry of disc formation
Johan E. Lindberg, Jes K. Jørgensen, Christian Brinch +6
Context: The R CrA cloud hosts a handful of Class 0/I low-mass young stellar objects. The chemistry and physics at scales AU in this cloud are dominated by the irradiation f…
Star Formation: Chemistry as a Probe of Embedded Protostars
Ruud Visser
The embedded phase of star formation is the crucial phase where most of the stellar mass is assembled. Velocity-resolved spectra reveal an infalling envelope, bipolar outflows, and…
Isotope selective photodissociation of N2 by the interstellar radiation field and cosmic rays
Alan N. Heays, Ruud Visser, Roland Gredel +4
Photodissociation of 14N2 and 14N15N occurs in interstellar clouds, circumstellar envelopes, protoplanetary discs, and other environments due to UV radiation from stellar sources a…
