Darryl Seligman is awarded an NSF Astronomy and Astrophysics Fellowship to carry out a program of research and education at Cornell University. Seligman will conduct research to maximize the scientific return from the newly discovered population of interstellar comets. Results from this study will reveal new insights into how the planet formation process varies throughout the galaxy. For the educational component of this project, Seligman will develop educational materials to help identify misinformation in media, using the case study of artificial origins of interstellar objects to motivate more pressing matters such as climate change and the global pandemic.The forthcoming Rubin Observatory Legacy Survey of Space and Time (LSST) will detect 1-3 interstellar objects every year. A subset of these objects will exhibit trajectories amenable to detailed ground and space-based follow-up observational characterization. With this motivation, Seligman will identify expected interstellar comet velocities (which trace galactic age) and compositions (which trace formation location) based on their original systems and formation locations within their protoplanetary disks. Seligman will predict exoplanet atmospheric compositional signatures of volatile enrichment from interstellar comet analogues which will inform our understanding of volatile delivery to short period exoplanets. Finally, Seligman will calculate detection rates and population statistics for interstellar objects that the LSST will discover that will be suitable targets for detailed ground and space based follow-up measurements. This research award is partially funded by a generous gift from Charles Simonyi to the NSF Astronomy division. The project includes significant contributions to Vera C. Rubin Observatory’s Legacy Survey of Space and Time.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.

达里尔·塞利格曼（Darryl Seligman）被授予NSF天文学和天体物理学奖学金，以在康奈尔大学（Cornell University）进行研究和教育计划。塞利格曼（Seligman）将进行研究，以最大程度地提高新发现的星际彗星人群的科学回报。这项研究的结果将揭示有关行星形成过程在整个银河系中如何变化的新见解。对于该项目的教育组成部分，塞利格曼将使用对星际物体的人为起源的案例研究来开发教育材料，以帮助识别媒体中的错误信息，以激励更紧迫的问题，例如气候变化和全球流行病。这些对象的一个​​子集将执行适合详细的地面和基于空间的随访观测表征的轨迹。有了这一动机，塞利格曼将根据其协议行行星际磁盘中的原始系统和地层位置确定预期的星际彗星速度（跟踪银河系年龄）和组成（跟踪形成位置）。塞利格曼（Seligman）将预测来自星际彗星类似物的挥发性富集的外部大气复合特征，这将使我们对我们对短期外部球星的挥发性递送的理解有所了解。最后，塞利格曼（Seligman）将计算出星际对象的检测率和人口统计数据，LSST将发现这将是详细地面和基于空间的随访测量值的合适目标。该研究奖部分由查尔斯·西尼尼（Charles Simonyi）向NSF天文学部的慷慨礼物提供资金。该项目包括对Vera C. Rubin天文台对时空的遗产调查的重要贡献。该奖项反映了NSF的法定使命，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
