中文摘要
在这个项目中,赫布博士和她的合作者将对低质量恒星的基本性质进行三部分研究。在过去的十年里,恒星团体已经清楚地看到,未演化的低质量恒星的质量和半径的理论模型与观测结果有很大的不同。在这项研究中,赫布博士将确定某些恒星的化学丰度,这些恒星的质量、半径和温度是准确已知的,探索磁感应活动对光度和半径测定的影响,并获得非常年轻的系统的关键数据,以测试导致完全氢聚变的相的模型。该项目预计将产生广泛的科学影响,因为基本恒星数据可用于各种应用,包括确定系外行星质量和表征恒星形成过程。研究小组还将继续与范德比尔特大学和菲斯克学院的学生合作。
英文摘要
In this project, Dr. Hebb and her collaborators will conduct a three-part study of the fundamental properties of low-mass stars. In the last decade, it has become apparent to the stellar community that theoretical models of the masses and radii of unevolved low-mass stars differ significantly from observations. In this study, Dr. Hebb will determine the chemical abundances of certain stars where the masses, radii, and temperatures are accurately known, explore the effect of magnetically-induced activity on the determinations of luminosity and radius, and obtain critical data on very young systems to test models of the phases leading up to full hydrogen fusion. The project is expected to have a broad scientific impact because fundamental stellar data can be used in a variety of applications, including the determination of exoplanet masses and the characterization of the star formation process. The research team will also continue their work with students at Vanderbilt and at Fisk College.
