中科院上海分院天马望远镜为Orion KL“体检”报告新鲜出炉！（图）
天马望远镜 射电复合线 分子谱线
2022/12/15
上海天文台科研团队利用65米口径的天马射电望远镜对猎户座Orion KL天体完成了迄今为止最大带宽（15 GHz）、最高灵敏度（mK量级）的Q波段谱线巡天工作。探测到约600条发射线，并成功从中证认出177条射电复合线和371条分子谱线。在天马望远镜探测到的53个分子品种中，21种是前人对Orion KL的Q波段搜寻工作[1]中未曾探测到的。这一工作表明了天马望远镜在探测弱线、开展大宽带谱线搜寻等...

Near-Infrared Photometric Variability of Stars Toward the Orion A Molecular Cloud
YY Ori BM Ori
2014/12/26
We present an analysis of J, H, and Ks time series photometry obtained with the southern 2MASS telescope over a 0.84◦×6◦ region centered near the Trapezium region of the Orion Nebula Clust...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Giant Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
star formation
2014/12/22
We present new, wide, and deep images in the 1.1 mm continuum and the CO ( 1–0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were taken with th...
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...
Orion rocks! Pebble-size particles may jump-start planet formation（图）
rock Pebble-size particles jump-start planet formation
2014/9/1
Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles...
'Death stars' in Orion blast planets before they even form（图）
Death stars they even form planets
2014/3/20
The Orion Nebula is home to hundreds of young stars and even younger protostars known as proplyds. Many of these nascent systems will go on to develop planets, while others will have their planet-form...
First Science Observations with SOFIA/FORCAST: 6 to 37 micron Imaging of the Central Orion Nebula
First Science Observations SOFIA/FORCAST micron Central Orion Nebula
2012/2/23
We present new mid-infrared images of the central region of the Orion Nebula using the newly commissioned SOFIA airborne telescope and its 5 -- 40 micron camera FORCAST. The 37.1 micron images represe...

the Orion star-forming region II. Stars
2011/1/13
We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance determinations in young stars in the Orion star-f...
During their infancy, stars are well known to expel matter violently in the form of well-defined,collimated outflows. A fairly unique exception is found in the Orion BN/KL star-forming region where a ...
