Subarcsecond Multi-line Observations of NH with VLA toward the Class 0 Source IRAS 16293-2422
Yoshihide Yamato, Yuri Aikawa, Kenji Furuya +2
Ammonia (NH) is one of the key volatiles that plays a central role in nitrogen chemistry and its evolution during the epoch of star and planet formation. We present subarcsecon…
ALMA observations of doubly deuterated water: Inheritance of water from the prestellar environment
S. S. Jensen, J. K. Jørgensen, L. E. Kristensen +5
Establishing the origin of the water D/H ratio in the Solar System is central to our understanding of the chemical trail of water during the star and planet formation process. Rece…
Water delivery from cores to disks: deuteration as a probe of the prestellar inheritance of H2O
K. Furuya, M. N. Drozdovskaya, R. Visser +5
We investigate the delivery of regular and deuterated forms of water from prestellar cores to circumstellar disks. We adopt a semi-analytical axisymmetric two-dimensional collapsin…
Reconstructing the history of water ice formation from HDO/H2O and D2O/HDO ratios in protostellar cores
K. Furuya, E. F. van Dishoeck, Y. Aikawa
Recent interferometer observations have found that the D2O/HDO abundance ratio is higher than that of HDO/H2O by about one order of magnitude in the vicinity of low-mass protostar…
Water deuteration and ortho-to-para nuclear spin ratio of H2 in molecular clouds formed via the accumulation of HI gas
K. Furuya, Y. Aikawa, U. Hincelin +4
We investigate the water deuteration ratio and ortho-to-para nuclear spin ratio of H2 (OPR(H2)) during the formation and early evolution of a molecular cloud, following the scenari…
