Pulsations in Rapidly Rotating Main Sequence Stars and Accreting White Dwarfs

比尔斯滕博士的研究将为研究快速自转恒星的天体地震学奠定理论基础。他将研究旋转对脉动模式稳定性的影响，并开发计算脉动特征函数和模式频率所需的方法。他的工作将对理解两类恒星的内部结构和演化产生影响：上主序恒星，特别是缓慢脉动的B星，有可能测量对流核心质量作为恒星演化状态的函数；以及吸积和快速旋转的白矮星，有可能确定这些系统中白矮星的质量、自转速度和吸积包层的性质。***

Bildsten, Lars AST-9731632 Dr. Bildsten's research will lay the theoretical groundwork for studies of astero-seismology of rapidly rotating stars. He will investigate the effect of rotation on pulsation mode stability, and develop methods required for the calculation of pulsation eigenfunctions and mode frequencies. His work will have implications for the understanding of the internal structure and evolution of two classes of stars : upper main sequence stars, particularly the slowly pulsating B stars, with the potential of measuring the convective core mass as a function of evolutionary state in the star, and accreting and rapidly rotating white dwarfs, with the potential of determining the masses, rotation rates, and properties of the accreted envelopes of white dwarf stars in these systems. ***
