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…
Photodissociation and chemistry of N in the circumstellar envelope of carbon-rich AGB stars
Xiaohu Li, T. J. Millar, Catherine Walsh +2
The envelopes of AGB stars are irradiated externally by ultraviolet photons; hence, the chemistry is sensitive to the photodissociation of N and CO, which are major reservoirs…
Complex organic molecules along the accretion flow in isolated and externally irradiated protoplanetary disks
Catherine Walsh, Eric Herbst, Hideko Nomura +2
(Abridged) The birth environment of the Sun will have influenced the conditions in the pre-solar nebula, including the attainable chemical complexity, important for prebiotic chemi…
ALMA hints at the presence of two companions in the disk around HD 100546
Catherine Walsh, Attila Juhasz, Paola Pinilla +10
HD 100546 is a well-studied Herbig Be star-disk system that likely hosts a close-in companion with compelling observational evidence for an embedded protoplanet at 68 AU. We presen…
Complex organic molecules in protoplanetary disks
Catherine Walsh, T. J. Millar, Hideko Nomura +5
(Abridged) Protoplanetary disks are vital objects in star and planet formation, possessing all the material which may form a planetary system orbiting the new star. We investigate…
