Alfvén waves in space plasmas have been studied for several decades. They have been recorded in the magnetospheres of planets (e.g., Earth, Jupiter), the solar wind, as well as the solar atmosphere. Despite the great differences in the plasma properties of these regions, the overarching themes of research are wave generation, wave propagation, and wave dissipation, which are three fundamental aspects of any kind of waves. A fourth aspect of waves is their application, either with direct benefit to humans or for scientific pursuit. This grant funds support for an international conference focusing on research in Alfven waves. Support includes travel for student and early career scientists to participate and present at the conference. An AGU monograph and a special issue of a journal are planned for disseminating the results presented.The Chapman Conference on Advances in Understanding Alfven Waves in the Sun and the Heliosphere will be held in Berlin, Germany from May 28-June 2, 2023. This interdisciplinary conference aims to bring together scientists from different communities to review and discuss the current state of research on Alfven waves in space plasmas, including the solar atmosphere, the solar wind, planetary magnetospheres and ionospheres, and laboratory plasmas (if relevant to space plasmas). Two prior wave-related Chapman conferences focused on ultra-low frequency waves (Magnetospheric ULF waves in 2005, Low-frequency waves in space plasmas in 2014). While the first one focused on waves in Earth’s magnetosphere, the second one was interdisciplinary, including waves in the solar atmosphere and other planetary magnetospheres (e.g., Jupiter, Mars).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

空间等离子体中的Alfvén波已经研究了数十年。它们已被记录在行星（例如地球，木星），太阳风以及太阳大气中的磁层中。尽管这些区域的等离子体特性存在很大差异，但研究的总体主题是波浪产生，波传播和波浪耗散，这是任何类型波的三个基本方面。海浪的第四个方面是它们的应用，要么是对人类的直接好处，要么是科学追求。这项赠款为一项针对阿尔凡浪潮研究的国际会议提供了支持。支持包括学生和早期职业科学家参加会议和出席会议的旅行。计划在2023年5月28日至6月2日至6月2日在德国的柏林举行有关理解Alfven浪潮的进步的Chapman会议，以了解艾古斯的专着和期刊的特刊。风，行星磁层和电离圈以及实验室等离子体（如果与空间等离子体有关）。两次与波浪有关的查普曼会议集中在超低频率波（2005年的磁层ULF波，2014年太空平原的低频波）上。虽然第一个重点是地球磁层中的波浪，但第二个是跨学科的，包括在太阳大气和其他行星磁层中的波浪（例如，木星，火星）。该奖项反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的criperia criperia criperia criperia criperia被视为通过评估而被视为珍贵的支持。
