论文摘要
经过将近三十年的发现，已经研究并详细研究并进行了详细的特征，其中一个重要例外：系外行星磁性。尽管许多调查试图检测来自系外行星的磁层无线电发射以直接测量其磁场强度，但它们尚未揭示明确的检测。然而，通过磁性星行相互作用测量其对宿主星的影响，间接检测外部球星磁场最近已成为一种突出的发现方法。罗马的第三篇论文（对磁化系外行星的无线电观测）列出了对附近八个系外行星托管系统的有针对性无线电调查的结果，该系统可能参与星空星际相互作用。这项调查以$ \ sim $ 5 GHz为Arecibo Radio Telescope进行，迄今为止的频率最大，同时提供了MJY级敏感性，超过$ 1 $ 1 S的集成时间。未检测到超球星引起的恒星无线电爆发。描述了用于磁性星行相互作用的候选系统的轨道相覆盖范围，并在等离子体流动式范式的背景下检查了调查结果，并在其他波长的情况下搜索了星形行星相互作用。
After nearly three decades of discovery, many exoplanetary systems have been studied and characterized in detail with one important exception: exoplanet magnetism. Although many surveys sought to detect magnetospheric radio emissions from exoplanets to directly measure their magnetic field strengths, they have yet to reveal an unambiguous detection. However, the indirect detection of exoplanet magnetic fields by measuring their influence on their host stars via magnetic star-planet interactions has recently gained prominence as an alternative method of discovery. This third paper of the ROME (Radio Observations of Magnetized Exoplanets) series presents the results of a targeted radio survey of eight nearby exoplanet-hosting systems that may engage in star-planet interactions. This survey, conducted with the Arecibo radio telescope at $\sim$5 GHz, has the greatest frequency coverage of any to date, while providing mJy-level sensitivity over $<$1 s integration times. No exoplanet-induced stellar radio bursts were detected. The orbital phase coverage of candidate systems for magnetic star-planet interactions is described, and the survey results are examined within the context of the plasma flow-obstacle paradigm and searches for star-planet interactions at other wavelengths.
