Pulsations in Rapidly Rotating Main Sequence Stars and Accreting White Dwarfs

比尔德斯滕，拉尔斯AST-9731632 比尔德斯滕博士的研究将为快速旋转恒星的星震学研究奠定理论基础。 他将研究旋转对脉动模式稳定性的影响，并开发计算脉动本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：高主序星，特别是缓慢脉动的B星，具有测量对流核心质量作为星星演化状态的函数的潜力，以及吸积和快速旋转的白色矮星，具有确定质量，旋转速率，和这些系统中白色矮星吸积包层的性质。 ***

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. ***
