The corona is the outermost layer of the Sun's atmosphere. Its plasma is accelerated and flows out into interplanetary space as a heated, supersonic wind. The details of energy and momentum transfer to the plasma remain debated. Alfvén wav...
Europa's ice thickness and subsurface structure characterized by the Juno microwave radiometer [0.03%]
木卫二冰层厚度及地下结构的特征分析——朱诺号微波辐射计观测结果
S M Levin,Z Zhang,S J Bolton et al.
S M Levin et al.
Jupiter's moon Europa is thought to harbour a saltwater ocean beneath a variously disrupted ice shell, and it is, thus, one of the highest priority astrobiology targets in the Solar System. Estimates of the ice-shell thickness range from 3 ...
Dynamical dark energy in light of the DESI DR2 baryonic acoustic oscillations measurements [0.03%]
基于DESI DR2重子声波振荡观测的动力学暗能量
Gan Gu,Xiaoma Wang,Yuting Wang et al.
Gan Gu et al.
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument (DESI) enables stringent tests with high-precision distance ...
The connection between the fastest astrophysical jets and the spin axis of their black hole [0.03%]
关于最快天体射流与其黑洞自转轴之间联系的研究

R P Fender
Astrophysical jets signpost the most extreme phenomena in the Universe. Despite a century of study, connections between the physics of black holes and the processes underpinning the formation and launch of these jets remain elusive. Here we...
Abundant supernova dust and heterogeneous aqueous alteration revealed by stardust in two lithologies of asteroid Bennu [0.03%]
柳叶石揭示出 Bennu 小行星两种岩石类型中的丰富超新星尘与非均质水化改造
Ann N Nguyen,Laura B Seifert,Kei Shimizu et al.
Ann N Nguyen et al.
The oldest constituents in chondritic samples are presolar grains that condensed in the outflows and explosions of dying stars. These grains divulge the types and concentrations of dust that seeded our Solar System. However, they are subjec...
Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map [0.03%]
詹姆斯 Webb太空望远镜凌日光谱的系外行星热结构的纬向和经度分布
Ryan C Challener,Megan Weiner Mansfield,Patricio E Cubillos et al.
Ryan C Challener et al.
Highly irradiated giant exoplanets known 'ultrahot Jupiters' are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, latitude and altitude. Previous observations have hinted at these ...
Textual interpretation of transient image classifications from large language models [0.03%]
大型语言模型中文字解释的瞬态图像分类
Fiorenzo Stoppa,Turan Bulmus,Steven Bloemen et al.
Fiorenzo Stoppa et al.
Modern astronomical surveys deliver immense volumes of transient detections, yet distinguishing real astrophysical signals (for example, explosive events) from bogus imaging artefacts remains a challenge. Convolutional neural networks are e...
Nitrogen- and oxygen-rich organic material indicative of polymerization in pre-aqueous cryochemistry on Bennu's parent body [0.03%]
富含氮和氧的有机物质表明 Bennu 母体上预水化学条件下发生了聚合反应
Scott A Sandford,Zack Gainsforth,Michel Nuevo et al.
Scott A Sandford et al.
Nitrogen-containing organic compounds play key biological roles, and their identification in primitive astromaterials such as meteorites can shed light on the origin of life. However, meteorites are typically contaminated by uncontrolled ex...
The variety and origin of materials accreted by Bennu's parent asteroid [0.03%]
本努母体 asteroid吸积物质的多样性及来源
J J Barnes,A N Nguyen,F A J Abernethy et al.
J J Barnes et al.
The first bodies to form in the Solar System acquired their materials from stars, the presolar molecular cloud and the protoplanetary disk. Asteroids that have not undergone planetary differentiation retain evidence of these primary accrete...
Detection of organic compounds in freshly ejected ice grains from Enceladus's ocean [0.03%]
土卫二海洋中有机化合物的检测
Nozair Khawaja,Frank Postberg,Thomas R O&#x;Sullivan et al.
Nozair Khawaja et al.
Saturn's moon Enceladus ejects a plume of ice grains and gases originating from a subsurface ocean via fractures near its south pole. The chemical characterization of organic material in such ice grains was previously conducted via the anal...
