中文摘要
这个项目将支持对白矮星上的热核爆炸的理论研究,这些白矮星正在经历来自附近同伴的质量转移。这种可燃燃料的转移引起了爆炸现象,通过目前和未来的光学观测很容易在遥远的星系中探测到这种现象。利用最新的计算工具和技术,该小组将研究氦向白矮星转移的结果,并调查重力和声波对爆炸产生和传播的影响。白矮星是恒星演化的主要产物,在典型星系中大约每年形成一次,但其中两颗白矮星需要特殊环境才能在短轨道周期的双星中结束生命,爆炸的细节尚不清楚。该项目预计将对恒星种群、恒星演化和宇宙学的研究产生许多影响,特别是在即将到来的大规模探测引力波、短周期双星和特殊超新星的时代。该项目的计算技术将免费提供给天体物理界,该小组将继续在科学教育和研究培训方面继续努力。
英文摘要
This project will support a theoretical investigation into thermonuclear explosions on white dwarfs that are experiencing mass transfer from a nearby companion. This transfer of combustible fuel gives rise to explosive phenomena that is easily detectable in distant galaxies by the current and future optical surveys. Using the latest computational tools and techniques, this group will study outcomes from the transfer of helium onto white dwarfs and investigate the effects of gravity and acoustic waves on the creation and propagation of explosions.White dwarfs are the dominant product of stellar evolution, forming at the rate of about one per year in a typical galaxy, but it requires special circumstances for two of them to end their lives in a binary with a short orbital period and the details of the explosion are not well understood. The project is expected to have many implications for the study of stellar populations, stellar evolution, and cosmology, particularly in the upcoming era of massive surveys to detect gravity waves, short-period binaries, and peculiar supernovae. Computational techniques from this project will be made freely available to the astrophysical community, and this group will continue ongoing efforts in science education and research training.
