Periodic Phenomena in Cataclysmic Binaries

帕特森博士通过广泛的观测项目，继续对灾难性双星系统的周期性进行测量。对灾变变量进行光度监测，以确定旋转星历表和表征超峰现象，是理解吸积过程和吸积对周期和自旋速率的长期影响的基础。帕特森和他的合作者建立了一个用于光度测量的小型望远镜网络，并获得了世界各地业余爱好者的观测支持，这些业余爱好者与专业天文学家密切合作，对许多系统进行监测。＊＊＊

Patterson, Joseph AST 96-18545 Dr. Patterson continues the measurement of periodicities in cataclysmic binary systems through an extensive observational program. Photometric monitoring of cataclysmic variables to determine rotational ephemerides and to characterize the phenomenon of superhumps is basic to understanding the accretion processes and the long-term effect of accretion on periods and spin rates. Patterson and his collaborators have established a network of small telescopes for photometry and enlisted the observing support of amateurs world-wide who provide monitoring of many systems in close collaboration with professional astronomers. ***
