Periodic radio and X-ray emission from an accreting white dwarf binary [0.03%]
一颗吸积白矮星双星的周期性射电和X射线辐射

Long-period radio transients (LPTs) are coherent bursts of polarized radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical origins of these systems. Astronomers have proposed magnetars...
Gravitational-wave constraints on the pair-instability mass gap and nuclear burning in massive stars [0.03%]
引力波对成对不稳定性质量缺口和大质量恒星核燃烧的限制

Pair instability should prevent the direct formation of black holes above about 50 M ⊙, creating a 'pair-instability' mass gap. Yet gravitational-wave observations have detected black holes in this mass range. These systems can be explaine...
Self-consistent numerical simulations for the formation and dynamics of solar prominences [0.03%]

Lisa-Marie Zessner et al.
Solar prominences are cool and dense plasma structures floating in the hot solar corona. They are ubiquitous features in the solar atmosphere, but their formation mechanism is still unclear. Here we perform comprehensive fully three-dimensi...

Meteorites are classified as either non-carbonaceous or carbonaceous, representing bodies that are likely to have formed in the inner or outer Solar System, respectively. Despite its location in the inner Solar System, the Earth is thought ...
Accurate determination of chemical abundances near a supermassive black hole [0.03%]

The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a unique tool to reliably measure the abundances of various elem...
Spatial variation of energy transport mechanisms within solar flare ribbons [0.03%]
太阳耀斑爆发条带内能量传输机制的时空变化研究
Graham S Kerr,Säm Krucker,Joel C Allred et al.
Graham S Kerr et al.
Solar flares release a tremendous amount of magnetic energy that subsequently manifests in several forms; the bulk of this energy is transported through the Sun's atmosphere and explosively heats the chromosphere. While hard X-ray observati...
Multiple outflows and delayed ejections revealed by early imaging of novae [0.03%]
早期对新星成像揭示的多次喷发和延迟喷发现象

Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism-impulsive ejection, multiple outflows or prolonged winds, or a common-envelope interactio...

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

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 ...
