Coronal Streamer Brightness Profiles Investigated with BriLo Using Parker Solar Probe White-Light Data [0.03%]
利用帕克太阳探测器白光数据研究冕流亮度分布
Greta M Cappello,Manuela Temmer,Andrea Lienhart et al.
Greta M Cappello et al.
We present the Brightness-Location (BriLo) method, a novel single-spacecraft technique which exploits the Thomson scattering theory for localizing extended coronal features such as streamers using white-light (WL) imaging. Beyond determinin...
Eruption-Related Ultraviolet Irradiance Enhancements Associated with Flares [0.03%]
与耀斑相关的火山爆发紫外线辐射增强效应

Luke Majury et al.
Large solar flares (GOES M-class or higher) are usually associated with eruptions of material. However, when considering flare irradiance enhancements and dynamics such as chromospheric evaporation, potential contributions from erupted mate...
Guided Waves Along a Density Interface in Partially Ionised Solar Plasmas [0.03%]
部分电离太阳等离子体中密度界面附近的导波现象研究

Nada F Alshehri et al.
Our study investigates the properties of Alfvén waves in partially ionised solar plasmas in the presence of steady, field-aligned, flows of charged and neutral particles. Our work aims to understand how such flows modify wave propagation a...
Evaluating Solar Wind Forecast Using Magnetic Maps That Include Helioseismic Far-Side Information [0.03%]
基于日震远侧磁图的太阳风预报验证
Stephan G Heinemann,Dan Yang,Shaela I Jones et al.
Stephan G Heinemann et al.
To model the structure and dynamics of the heliosphere well enough for high-quality forecasting, it is essential to accurately estimate the global solar magnetic field used as inner boundary condition in solar wind models. However, our unde...
Joint Inversion of Radionuclide Production Rate Data and Thermoremanent Magnetic Records over the Holocene [0.03%]
基于全新世的放射核素产生率数据和热剩磁记录的联合反演

Maximilian Arthus Schanner
Understanding the Sun's role in past climate change requires knowledge of solar variability over millennia. While direct sunspot records span only the last 400 years, longer-term changes are inferred from cosmogenic radionuclides like 14C a...
Numerical Modeling of Prominences and Coronal Rain with the MPI-AMRVAC Code [0.03%]
带有MPI-AMRVAC代码的太阳日冕 prominences和 coronal rain数值模拟

Sophie Boswell et al.
In situ measurements of kinetic scale current sheets in the solar wind show that they are often approximately force-free although the plasma β is of order one. They frequently display systematic asymmetric and anti-correlated spatial v...
Multispacecraft Observations of the 2024 September 9 Backside Solar Eruption That Resulted in a Sustained Gamma Ray Emission Event [0.03%]
多航天器观测到的2024年9月9日太阳背面爆发事件及其持续的伽马射线发射现象

Nat Gopalswamy et al.
We report on the 2024 September 9 sustained gamma-ray emission (SGRE) event observed by the Large Area Telescope (LAT) on board the Fermi satellite. The hevent was associated with a backside solar eruption observed by multiple spacecraft su...
The Sunspot Solar Observatory Data Archive: Continuing Operations at the Dunn Solar Telescope [0.03%]
