Dust-gas chemistry in AGB outflows: Chemical modelling of dust-gas chemistry within AGB outflows I. Effect on the gas-phase chemistry
M. Van de Sande, C. Walsh, T. P. Mangan +1
Chemical modelling of AGB outflows is typically focused on either non-thermodynamic equilibrium chemistry in the inner region or photon-driven chemistry in the outer region. We inc…
Chronology of Episodic Accretion in Protostars -- an ALMA survey of the CO and HO snowlines
Tien-Hao Hsieh, Nadia M. Murillo, Arnaud Belloche +6
Episodic accretion has been used to explain the wide range of protostellar luminosities, but its origin and influence on the star forming process are not yet fully understood. We p…
Abundant refractory sulfur in protoplanetary disks
Mihkel Kama, Oliver Shorttle, Adam S. Jermyn +5
Sulfur is one of the most abundant elements in the Universe, with important roles in astro-, geo-, and biochemistry. Its main reservoirs in planet-forming disks have previously elu…
The First Detection of 13C17O in a Protoplanetary Disk: a Robust Tracer of Disk Gas Mass
Alice S. Booth, Catherine Walsh, John D. Ilee +4
Measurements of the gas mass are necessary to determine the planet formation potential of protoplanetary disks. Observations of rare CO isotopologues are typically used to determin…
Cometary compositions compared with protoplanetary disk midplane chemical evolution. An emerging chemical evolution taxonomy for comets
Christian Eistrup, Catherine Walsh, Ewine F. van Dishoeck
[Abridged] With a growing number of molecules observed in many comets, and an improved understanding of chemical evolution in protoplanetary disk midplanes, comparisons can be made…
First detections of H13CO+ and HC15N in the disk around HD 97048: Evidence for a cold gas reservoir in the outer disk
Alice S. Booth, Catherine Walsh, John D. Ilee
Observations of different molecular lines in protoplanetary disks provide valuable information on the gas kinematics, as well as constraints on the radial density and temperature s…
