Deuterium-to-hydrogen (D/H) enrichments in molecular species provide clues about their original formation environment. The organic materials in primitive solar system bodies generally have higher D/H ratios and show greater D/H variation wh...
COMPOSITIONAL DIVERSITY IN THE ATMOSPHERES OF HOT NEPTUNES, WITH APPLICATION TO GJ 436b [0.03%]
热海王星大气的组成多样性及其在GJ 436b上的应用
J I Moses,M R Line,C Visscher et al.
J I Moses et al.
Neptune-sized extrasolar planets that orbit relatively close to their host stars - often called "hot Neptunes" - are common within the known population of exoplanets and planetary candidates. Similar to our own Uranus and Neptune, inefficie...
CHEMICAL CONSEQUENCES OF THE C/O RATIO ON HOT JUPITERS: EXAMPLES FROM WASP-12b, COROT-2b, XO-1b, AND HD 189733b [0.03%]
高温巨行星上C/O比的化学效应:WASP-12b、COROT-2b、XO-1b和HD 189733b的例子
J I Moses,N Madhusudhan,C Visscher et al.
J I Moses et al.
Motivated by recent spectroscopic evidence for carbon-rich atmospheres on some transiting exo-planets, we investigate the influence of the C/O ratio on the chemistry, composition, and spectra of extrasolar giant planets both from a thermoch...
The Origins of Young Stars in the Direction of the Leading Arm of the Magellanic Stream: Abundances, Kinematics, and Orbits [0.03%]
麦哲伦流前锋臂方向恒星起源:丰度、动力学和轨道属性

Lan Zhang et al.
We explore the origins of the young B-type stars found by Casetti-Dinescu et al. (2014) at the outskirts of the Milky-Way disk in the sky region of Leading Arm of the Magellanic Stream. High-resolution spectroscopic observations made with t...
Double-degenerate Carbon-Oxygen and Oxygen-Neon White Dwarf Mergers: A New Mechanism for Faint and Rapid Type Ia Supernovae [0.03%]
双简并碳氧和氧氖白矮星合并:Ia型超新星的新机制
Rahul Kashyap,Tazkera Haque,Pablo Lorén-Aguilar et al.
Rahul Kashyap et al.
Type Ia supernovae (SNe Ia) originate from the thermonuclear explosion of carbon-oxygen white dwarfs (CO WDs), giving rise to luminous optical transients. A relatively common variety of subluminous SNe Ia events, referred to as SNe Iax, are...

Terrestrial exoplanets in the canonical habitable zone may have a variety of initial water fractions due to random volatile delivery by planetesimals. If the total planetary water complement is high, the entire surface may be covered in wat...
COORDINATED ANALYSIS OF TWO GRAPHITE GRAINS FROM THE CO3.0 LAP 031117 METEORITE: FIRST IDENTIFICATION OF A CO NOVA GRAPHITE AND A PRESOLAR IRON SULFIDE SUBGRAIN [0.03%]

The planetary mass and radius sensitivity of exoplanet discovery capabilities has reached into the terrestrial regime. The focus of such investigations is to search within the Habitable Zone where a modern Earth-like atmosphere may be a via...
Reduction of Thermal Conductive Flux by Non-local Effects in the Presence of Turbulent Scattering [0.03%]
考虑湍流散射时非局域效应的热传导通量减少机制

The heat flux in a plasma is determined by the degree of anisotropy in the particle distribution function, which is in turn driven by gradients in the ambient density and temperature. When the mean free path at the thermal speed is substant...
Identification of Multiple Hard X-Ray Sources in Solar Flares: A Bayesian Analysis of the 2002 February 20 Event [0.03%]
基于贝叶斯分析识别耀斑中的多个硬X射源:以2002年2月20日事件为例
Federica Sciacchitano,Alberto Sorrentino,A Gordon Emslie et al.
Federica Sciacchitano et al.
The hard X-ray emission in a solar flare is typically characterized by a number of discrete sources, each with its own spectral, temporal, and spatial variability. Establishing the relationship among these sources is critical to determining...
