2014/12/26
We present Submillimeter Wave Astronomy Satellite observations of water vapor in two cold starless clouds, B68 and core D in ρ Ophiuchi. Sensitive nondetections of the 110-101 transition of o-H2O are ...
A survey of 557 GHz water vapor emission in the NGC 1333 molecular cloud

Using NASA's Submillimeter Wave Astronomy Satellite (SWAS), we have examined the production of water in quiescent and shocked molecular gas through a survey of the 556.936 GHz 110-101 transition of or...
We have observed six clouds along the line of sight toward W49A using the Submillimeter Wave Astronomy Satellite and several ground-based observatories. The ortho-H2O 110 → 101 and OH (1665 and 1667 M...
We present detections of the ground-state 110→ 101 transition of ortho-H2O at 557 GHz in 18 molecular outflows based on data from the Submillimeter Wave Astronomy Satellite (SWAS). These results are c...
Herschel/HIFI measurements of the ortho/para ratio in water towards Sagittarius B2(M) and W31C*

We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-H216O and H218O in absorption towards Sagittarius B2(M) and W31C. The ortho/para ratio in water in th...
Transient liquid water near an artificial heat source on Mars

We describe the response of icy martian soil to a localized heat source using analytical and numerical models. Our motivation is to understand the implications of a landing failure in which a radioiso...

December 6, 2006，The discoveries were made as part of a campaign to monitor curious light-toned deposits that had been observed on the walls of craters in the mid-latitudes of Mars (from 30 to 60 degr...
