Missing water in Class I protostellar disks
Daniel Harsono, Magnus Persson, Alyssa Ramos +10
Water is a key volatile that provides insights into the initial stages of planet formation. The low water abundances inferred from water observations toward low-mass protostellar o…
Nitrogen isotope fractionation in protoplanetary disks
Ruud Visser, Simon Bruderer, Paolo Cazzoletti +3
Aims: The two stable isotopes of nitrogen, 14N and 15N, exhibit a range of abundance ratios both inside and outside the solar system. The elemental ratio in the solar neighborhood…
Imaging the water snowline in a protostellar envelope with HCO
Merel L. R. van 't Hoff, Magnus V. Persson, Daniel Harsono +5
Snowlines are key ingredients for planet formation. Providing observational constraints on the locations of the major snowlines is therefore crucial for fully connecting planet com…
CN rings in full protoplanetary disks around young stars as probes of disk structure
P. Cazzoletti, E. F. van Dishoeck, R. Visser +2
Bright ring-like structure emission of the CN molecule has been observed in protoplanetary disks. We investigate whether such structures are due to the morphology of the disk itsel…
Destruction of Refractory Carbon in Protoplanetary Disks
Dana E. Anderson, Edwin A. Bergin, Geoffrey A. Blake +3
The Earth and other rocky bodies in the inner solar system contain significantly less carbon than the primordial materials that seeded their formation. These carbon-poor objects in…
Origin of warm and hot gas emission from low-mass protostars: Herschel-HIFI observations of CO J=16-15. I. Line profiles, physical conditions, and H2O abundance
L. E. Kristensen, E. F. van Dishoeck, J. C. Mottram +18
(Abridged) Through spectrally unresolved observations of high-J CO transitions, Herschel-PACS has revealed large reservoirs of warm (300 K) and hot (700 K) molecular gas around low…
