Evolutionary and Statistical Studies of Close Binary Stars

Webbink博士将通过研究系统角动量的损失来开展一个关于双星演化的研究项目。他的理论研究项目与澳大利亚国立大学的研究人员合作，将研究被认为会导致角动量损失的磁制动现象，特别是恒星风质量损失率与表面磁场强度的关系，以及磁场强度与恒星自转速度的关系。他还将研究强磁白矮星上的吸积，白矮星和吸积盘对供体恒星加热的影响，以及白矮星在新星爆炸中质量损失的影响。此外，他计划出版一份紧密双星系统的目录，以帮助进一步研究这些系统，并将其用于人口综合研究和寻找可用于确定基本恒星参数的高自运动食双星。＊＊＊

Webbink, Ronald AST 96-18462 Dr. Webbink will carry out a program of research on the evolution of binary stars through studies of the loss of systemic angular momentum. His theoretical research program, in collaboration with researchers at the Australian National University, will examine the phenomenon of magnetic braking thought to drive angular momentum loss, particularly the dependence of stellar wind mass loss rate on surface magnetic field strength, and of magnetic field strength on stellar rotation rate. He will also investigate the case of accretion onto strongly magnetic white dwarfs, the effects of heating of the donor star by the white dwarf and accretion disk, and the effects of white dwarf mass loss in novae explosions. In addition, he plans to publish a catalog of close binary systems as an aid to further study of the systems, and to use it for population synthesis studies and a search for high proper-motion eclipsing binaries that can be used for the determination of fundamental stellar parameters. ***
