In the study of planets around other stars, telescopic observations called radial velocity measurements are needed for two reasons: First, these observations are one of the best methods for finding planets that are located very close to their stars. Second, for planets that move in front of their stars in their orbits, these observations tell astronomers the weight of the planets. The Third Workshop on Extremely Precise Radial Velocities will bring together 150 - 200 astronomers, engineers, and mathematicians to discuss ways to improve instruments and computing methods so that they can find and study the smallest Earth-like planets around other stars. This conference will serve the national interest by promoting the progress of science when successes, challenges, and plans to improve the precision of the telescopic observations needed to find these Earth-like planets are discussed and shared. The conference will last four days, and have talks and posters mixed with group discussions.The Principal Investigator requests support for a conference entitled "The Third Workshop on Extremely Precise Radial Velocities (EPRV III)." This international workshop will emphasize the discipline of extremely precise (1 m/s) Doppler velocimetry of stars, focusing on specific challenges toward achieving the 10 cm/s radial velocity precision needed to detect and characterize Earth analogs around G and K dwarf stars. The conference will assemble 150 to 200 instrument team participants, including observational and theoretical astronomers, statisticians, engineers, practitioners in high performance computing, heliophysicists, and others bridging these categories. The participants will address the significant hardware challenges specific to building EPRV instruments, the successes and lessons learned from the latest generation of EPRV instrumentation, new statistical and computational methods for signal extraction, analysis and jitter mitigation, and physical models and spectral diagnostics of stellar granulation and other sources of jitter. One planned outcome is a white paper directed at the role of EPRV instruments for the upcoming astronomy and astrophysics Decadal Survey. The conference is planned to last four days and will consist of invited plenary talks with time allocated for discussion between talks, breakout sessions on more specialized topics, and posters that will be displayed for the entire meeting.

在研究其他恒星周围的行星时，需要进行称为径向速度测量的望远镜观测，原因有二：首先，这些观测是寻找距离恒星非常近的行星的最佳方法之一。 其次，对于在轨道上运行在恒星前面的行星，这些观测告诉天文学家行星的重量。第三届极精确径向速度研讨会将汇集150 - 200名天文学家，工程师和数学家，讨论如何改进仪器和计算方法，以便他们能够发现和研究其他恒星周围最小的类地行星。本次会议将通过促进科学进步来服务于国家利益，讨论和分享成功，挑战和计划，以提高寻找这些类地行星所需的望远镜观测的精度。本次会议将持续四天，会议内容包括演讲、海报和小组讨论。主要研究者请求支持一个名为“第三届极精确径向速度研讨会（EPRV III）”的会议。“这个国际研讨会将强调恒星的极精确（1 m/s）多普勒测速的学科，重点是实现10 cm/s径向速度精度所需的具体挑战，以检测和表征G和K矮星周围的地球类似物。 会议将聚集150至200名仪器团队参与者，包括观测和理论天文学家，统计学家，工程师，高性能计算从业者，太阳能科学家和其他桥接这些类别的人。与会者将讨论特定于构建EPRV仪器的重大硬件挑战，最新一代EPRV仪器的成功和经验教训，用于信号提取，分析和抖动缓解的新统计和计算方法，以及恒星颗粒和其他抖动源的物理模型和光谱诊断。 一个计划的成果是一份针对EPRV仪器在即将到来的天文学和天体物理学十年调查中的作用的白色文件。会议计划持续四天，将包括邀请的全体会议，会议之间分配时间进行讨论，关于更专业主题的分组会议，以及将在整个会议上展示的海报。
