Upper limit for the D2H+ ortho-to-para ratio in the prestellar core 16293E (CHESS)
C. Vastel, P. Caselli, C. Ceccarelli +6
The H3+ ion plays a key role in the chemistry of dense interstellar gas clouds where stars and planets are forming. The low temperatures and high extinctions of such clouds make di…
Multi-line detection of O2 toward rho Oph A
R. Liseau, P. F. Goldsmith, B. Larsson +36
Models of pure gas-phase chemistry in well-shielded regions of molecular clouds predict relatively high levels of molecular oxygen, O2, and water, H2O. Contrary to expectation, the…
A study of deuterated water in the low-mass protostar IRAS16293-2422
Audrey Coutens, Charlotte Vastel, Emmanuel Caux +6
The HDO/H2O ratio is a powerful diagnostic to understand the evolution of water from the first stages of star formation to the formation of planets and comets. Our aim is to determ…
