中国科学院地化所在嫦娥五号月壤撞击玻璃中发现多种来源的OH和分子H2O（图）
太阳风 演化 遥感探测
2024/6/25
月表水的来源和保存是月球科学研究的重要问题，对月球水资源的分布和提取利用、认识无大气天体表面水的形成演化以及类地行星水来源等问题具有重要意义。前期的遥感探测和样品分析揭示了月壤中普遍存在太阳风成因水（OH/H2O），然而太阳风成因水的演化以及月表分子H2O的存在与否仍存在争议，限制了对月表水形成和保存过程的认识，需结合月球样品分析开展深入的研究。
Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sagittarius B2(M) *,**
H2O+ massive star forming
2014/12/22
H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all spiral arm clouds be...
Detection of OH+ and H2O+ towards Orion KL
OH+ H2O+
2014/12/20
We report observations of the reactive molecular ions OH+, H2O+, and H3O+ towards Orion KL with Herschel/HIFI. All three N = 1-0 fine-structure transitions of OH+ at 909, 971, and 1033 GHz and both fi...
The properties and polarization of the H2O and CH3OH maser environment of NGC7538-IRS1
Stars: formation - masers: water, methanol - polarization - magnetic fi elds - ISM: individual: NGC7538
2011/10/17
NGC7538 is a complex massive star-forming region. The region is composed of several radio continuum sources, one of which is IRS1, a high-mass protostar, from which a 0.3 pc molecular bipolar outflow ...
Observation of H2O in a strongly lensed Herschel-ATLAS source at z=2.3
Galaxies: high-redshift – Galaxies: starburst – Galaxies: active – Infrared: galaxies – Submillimeter: galaxies – Radiolines: galaxies
2011/10/19
The Herschel survey, H-ATLAS, with its large areal coverage, has recently discovered a number of bright, strongly lensed high-z submillimeter galaxies. The strong magnification makes it possible to st...
The HDO/H2O ratio in gas in the inner regions of a low-mass protostar
astrochemistry — stars formation — protoplanetary disks —ISM
2010/11/15
The HDO/H2O abundance ratio is thought to be a key diagnostic on the evolution of water during the star- and planet-formation process and thus on its origin on Earth. We here present millimeter-wavele...
