Margaret Lazzarini is awarded an NSF Astronomy and Astrophysics Fellowship to carry out a program of research and education at the California Institute of Technology. Using observations at infrared, optical, ultraviolet, and X-ray wavelengths, Lazzarini will study properties of high-mass X-ray binary (HMXB) systems containing a star and a massive compact object (CO) such as a neutron star or a black hole. Results from this project will allow astronomers to better understand binary stellar evolution and how HMXBs yield binary COs which can undergo mergers to produce gravitational waves. Lazzarini will also conduct a weekly after school enrichment program which will provide astronomy research experiences to high school students from underserved communities.Lazzarini will use photometry, time-resolved spectroscopy, and computational binary evolution modeling to place precise constraints on the allowed common envelope efficiency and supernova kick magnitudes of over 200 HMXBs in three nearby galaxies: M31, M33, and the Small Magellanic Cloud. By constraining these two parameters in a large sample of HMXBs in a wide range of galactic environments, this project will greatly improve formation models of CO mergers via isolated binary stellar evolution and enable precise estimates of the rates of merger events producing GWs. This project advances the goals of the NSF Windows on the Universe Big Idea.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.

玛格丽特·拉扎里尼（Margaret Lazzarini）荣获美国国家科学基金会（NSF）天文学和天体物理学奖学金，在加州理工学院开展研究和教育项目。 Lazzarini将利用红外、光学、紫外和X射线波长的观测，研究包含一颗星星和一颗大质量致密天体（CO）（如中子星星或黑洞）的大质量X射线双星（HMXB）系统的性质。 该项目的结果将使天文学家能够更好地了解双星演化以及HMXB如何产生可以合并产生引力波的双星CO。 Lazzarini还将进行每周一次的课后充实计划，为来自服务水平低下社区的高中生提供天文学研究经验。Lazzarini将使用测光，时间分辨光谱学和计算双星演化模型来精确限制三个附近星系中允许的共同包络效率和超过200个HMXB的超新星踢等：M31、M33和小麦哲伦星云 通过在广泛的银河系环境中的大样本HMXB中限制这两个参数，该项目将大大改善通过孤立的双星演化形成CO合并的模型，并能够精确估计合并事件产生GWs的速率。 该项目推进了NSF宇宙大创意窗口的目标。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
