A Supernova at 50 pc: Effects on the Earth's Atmosphere and Biota [0.03%]
距离地球2万光年内的超新星爆发对地球大气及生物圈的影响
A L Melott,B C Thomas,M Kachelrieß et al.
A L Melott et al.
Recent 60Fe results have suggested that the estimated distances of supernovae in the last few million years should be reduced from ∼100 to ∼50 pc. Two events or series of events are suggested, one about 2.7 million years to 1.7 million ye...
The Maser Emitting Structure and Time Variability of the SIS Lines J = 14 - 13 and 15 - 14 in IRC+10216 [0.03%]

J P Fonfría et al.
We present new high angular resolution interferometer observations of the υ = 0 J = 14 - 13 and 15 - 14 SiS lines towards IRC+10216, carried out with CARMA and ALMA. The maps, with angular resolutions of ≃0⋅″25and0⋅...

We present the detection of C4H2 for first time in the envelope of the C-rich AGB star IRC+10216 based on high spectral resolution mid-IR observations carried out with the Texas Echelon-cross-Echelle Spectrograph (TEXES) mounted on the Infr...
Is the gas-phase OH+H2CO reaction a source of HCO in interstellar cold dark clouds? A kinetic, dynamic and modelling study [0.03%]
OH+H2CO反应是否是分子云中HCO的来源？基于动力学、动态及模型的研究
A J Ocaña,E Jiménez,B Ballesteros et al.
A J Ocaña et al.
Chemical kinetics of neutral-neutral gas-phase reactions at ultralow temperatures is a fascinating research subject with important implications on the chemistry of complex organic molecules in the interstellar medium (T∼10-100K). Scarce ki...
A Molecular-Line Study of the Interstellar Bullet Engine IRAS05506+2414 [0.03%]
星际子弹引擎IRAS05506+2414的分子谱线研究
Raghvendra Sahai,Chin-Fei Lee,Carmen Sánchez Contreras et al.
Raghvendra Sahai et al.
We present interferometric and single-dish molecular line observations of the interstellar bullet-outflow source IRAS05506+2414, whose wide-angle bullet spray is similar to the Orion BN/KL explosive outflow and likely arises from an entirel...
First Laboratory Detection of Vibration-Rotation Transitions of 12CH+ and 13CH+ and Improved Measurement of their Rotational Transition Frequencies [0.03%]
首次实验检测到12CH+和13CH+的振动转动跃迁及改进其转动跃迁频率的测量
José L Doménech,Pavol Jusko,Stephan Schlemmer et al.
José L Doménech et al.
The long-searched C-H stretches of the fundamental ions CH+ and 13CH+ have been observed for the first time in the laboratory. For this, the state-dependent attachment of He atoms to these ions at cryogenic temperatures has been exploited t...
The Role of Pickup Ion Dynamics Outside of the Heliopause in the Limit of Weak Pitch Angle Scattering: Implications for the Source of the IBEX Ribbon [0.03%]
日球层外拾取离子动力学的弱漂移散射作用于星际边界探测器带状结构源探测的影响

E J Zirnstein
We present a new model of the Interstellar Boundary Explorer (IBEX) ribbon based on the secondary energetic neutral atom (ENA) mechanism, under the assumption that there is negligible pitch angle scattering of pickup ions (PUIs) outside the...
Parameter Estimation for Gravitational-wave Bursts with the BayesWave Pipeline [0.03%]
