Magnetic reconnection in the solar corona is thought to be unstable with the formation of multiple interacting plasmoids, and previous studies have shown that plasmoid dynamics can trigger MHD waves of different modes propagating outward fr...
η CARINAE'S DUSTY HOMUNCULUS NEBULA FROM NEAR-INFRARED TO SUBMILLIMETER WAVELENGTHS: MASS, COMPOSITION, AND EVIDENCE FOR FADING OPACITY [0.03%]
卡星η的尘埃蛋状星云：从近红外到亚毫米波段的观测、质量及组成和遮蔽减弱现象的证据
Patrick W Morris,Theodore R Gull,D John Hillier et al.
Patrick W Morris et al.
Infrared observations of the dusty, massive Homunculus Nebula around the luminous blue variable η Carinae are crucial to characterize the mass-loss history and help constrain the mechanisms leading to the Great Eruption. We present the 2.4...
TOWARD AN UNDERSTANDING OF GRB PROMPT EMISSION MECHANISM: II. PATTERNS OF PEAK ENERGY EVOLUTION AND THEIR CONNECTION TO SPECTRAL LAGS [0.03%]
伽玛暴瞬时辐射机制研究之二：峰值能量演变规律及其与能谱滞后量的关系

The prompt emission phase of gamma-ray bursts (GRBs) exhibits two distinct patterns of the peak-energy (E p ) evolution; i.e., time-resolved spectral analyses of νF ν spectra of broad pulses reveal (1) "hard-to-soft" and (2) "flux-trackin...
Beyond Optical Depth: Future Determination of Ionization History from the Cosmic Microwave Background [0.03%]
光学深度之外：从宇宙微波背景确定离子史的未来方法

D J Watts et al.
We explore the fundamental limits to which reionization histories can be constrained using only large-scale cosmic microwave background (CMB) anisotropy measurements. The redshift distribution of the fractional ionization x e (z) affects th...
Analytic Calculation of Covariance between Cosmological Parameters from Correlated Data Sets, with an Application to SPTpol [0.03%]
基于相关数据集的宇宙学参数协方差的解析计算及其在SPTpol中的应用

Consistency checks of cosmological data sets are an important tool because they may suggest systematic errors or the type of modifications to ΛCDM necessary to resolve current tensions. In this work, we derive an analytic method for calcul...
Modeling a Carrington-scale Stellar Superflare and Coronal Mass Ejection from κ 1 Cet [0.03%]
基于κ1室女座的类太阳恒星超级耀发及日冕物质抛射的卡灵顿事件模拟研究

Observations from the Kepler mission have revealed frequent superflares on young and active solar-like stars. Superflares result from the large-scale restructuring of stellar magnetic fields, and are associated with the eruption of coronal ...
Analysis of Small-scale Magnetic Flux Ropes Covering the Whole Ulysses Mission [0.03%]

Small-scale magnetic flux ropes in the solar wind have been studied for decades via both simulation and observation. Statistical analysis utilizing various in situ spacecraft measurements is the main observational approach, which helps inve...

The evolved, massive highly eccentric binary system, η Car, underwent a periastron passage in the summer of 2014. We obtained two coordinated X-ray observations with XMM-Newton and NuSTAR during the elevated X-ray flux state and just befor...

The effects of turbulence in the very local interstellar medium (VLISM) have been proposed by Giacalone & Jokipii (2015) to be important in determining the structure of the Interstellar Boundary Explorer (IBEX) ribbon via particle trapping ...
GALAXY STRUCTURE, STELLAR POPULATIONS, AND STAR FORMATION QUENCHING AT 0.6 ≲ z ≲ 1.2 [0.03%]

We use both photometric and spectroscopic data from the Hubble Space Telescope to explore the relationships among 4000 Å break (D4000) strength, colors, stellar masses, and morphology, in a sample of 352 galaxies with log(M */M ⊙) > 9.44 ...
