MHD远程数值模拟:日冕物质抛射的演化

MHD Remote Numerical Simulations: Evolution of Coronal Mass Ejections

L. Hernandez-Cervantes, A. Santillan, A. R. Gonzalez-Ponce

摘要:

日冕物质抛射(CME)是太阳喷发到行星际空间的数十亿吨等离子体,其中嵌入了来自太阳日冕的磁场。这些扰动在日地关系中,特别是在空间天气中起着非常重要的作用。在这项工作中,我们提出了一些初步的软件开发结果在墨西哥国立自治大学进行远程MHD数值模拟。这是通过一个基于Web的界面来研究CME在行星际介质中的演化,并将结果存储到数据库中。新的天体物理计算工具被称为墨西哥虚拟太阳天文台(MVSO),旨在创建可能有助于解释观测太阳数据的理论模型。

英文摘要:

Coronal mass ejections (CMEs) are solar eruptions into interplanetary space of as much as a few billion tons of plasma, with embedded magnetic fields from the Sun's corona. These perturbations play a very important role in solar--terrestrial relations, in particular in the spaceweather. In this work we present some preliminary results of the software development at the Universidad Nacional Autonoma de Mexico to perform Remote MHD Numerical Simulations. This is done to study the evolution of the CMEs in the interplanetary medium through a Web-based interface and the results are store into a database. The new astrophysical computational tool is called the Mexican Virtual Solar Observatory (MVSO) and is aimed to create theoretical models that may be helpful in the interpretation of observational solar data.
