Title: CoSEE-Cat：从太阳轨道器的原位和远程观测结合得到的综合太阳高能电子事件目录——目录描述和首次统计结果

Abstract: (abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs) measured in situ can be linked to solar flares and coronal mass ejections (CMEs), which can be observed remotely in radio, optical, UV and X-rays. Solar Orbiter, equipped with a wide range of remote-sensing and in situ detectors, provides an excellent opportunity to investigate SEEs and their solar origin from the inner heliosphere. The Comprehensive Solar Energetic Electron event Catalogue (CoSEE-Cat) provides details for all SEE events measured in situ by Solar Orbiter, as well as associated flares, CMEs, and radio bursts. The catalogue contains key parameters of the SEEs, as derived from the Energetic Particle Detector (EPD), complemented with basic parameters of associated X-ray flares provided by STIX, information on eruptive phenomena seen by EUI, characteristics of type III radio bursts observed by RPW, and indications of CME observed by Metis and SoloHI. The conditions in interplanetary space were characterised using SWA and MAG measurements. Finally, data-driven modelling with the Magnetic Connectivity Tool provided an independent estimate of the solar source position of the SEEs. The first data release contains 303 SEE events observed from November 2020 until the end of 2022. In this paper, we describe the catalogue and provide a first statistical analysis. Preliminary results support the flare-related origin of events with an impulsive ion composition and the association of gradual events with extended structures such as CME-driven shocks or erupting flux ropes. We also show that the commonly observed delays of the solar release times of the SEEs relative to the associated X-ray flares and type III radio bursts are at least partially due to propagation effects.

Abstract: (摘要) 太阳粒子的加速及其在行星际空间中的传播是日球物理的关键主题。特别是现场测量的太阳高能电子(SEEs)可以与太阳耀斑和日冕物质抛射(CMEs)相关联，这些现象可以在射电、光学、紫外线和X射线中远程观测到。太阳轨道器配备了广泛的远程探测和现场探测器，为从内日球层研究SEEs及其太阳起源提供了绝佳的机会。综合太阳高能电子事件目录(CoSEE-Cat)提供了太阳轨道器现场测量的所有SEEs事件的详细信息，以及相关的耀斑、CMEs和射电爆发。该目录包含从能量粒子探测器(EPD)得出的SEEs的关键参数，并补充了由STIX提供的相关X射线耀斑的基本参数，EUI看到的爆发现象的信息，RPW观察到的III型射电爆发的特征，以及Metis和SoloHI观测到的CME的指示。通过SWA和MAG测量表征了行星际空间的条件。最后，使用磁连通性工具进行数据驱动建模，提供了SEEs太阳源位置的独立估计。第一次数据发布包含2020年11月至2022年底观测到的303个SEEs事件。在本文中，我们描述了该目录并提供了一个初步的统计分析。初步结果支持具有脉冲离子成分的事件的耀斑相关起源，并表明渐进事件与扩展结构如CME驱动的激波或喷发通量绳有关。我们还表明，通常观测到的SEEs的太阳释放时间相对于相关X射线耀斑和III型射电爆发的延迟至少部分是由于传播效应。
