标题： Evolution of short-period cataclysmic variables: implications from eclipse modeling and stage A superhump method (with New Year's gift)

摘要： 2013年，利用阶段A超级耀斑（增长型超级耀斑）确定矮新星质量比的方法被确立。 该方法是一种动力学方法，因为它仅依赖于天体力学。 它不依赖于实验校准。 从那时起，已有超过100个天体通过这种方法进行了测量。 本文提供了该方法的更新描述。 与现代掩食建模方法（被认为是黄金标准）的结果比较表明，这两种方法非常一致，并且阶段A超级耀斑方法已被确认与现代掩食建模方法一样准确和可靠。 使用前者的天体数量现在是后者的几倍，前者对于研究灾变变量的终端演化是不可或缺的。 我还展示了其他小组过去的研究假设了错误的超级耀斑超额关系，导致讨论演化时出现偏差。 我还推导出了一个新的阶段B超级耀斑实验关系。 更新的最小周期演化轨迹表明，角动量损失比引力波辐射预期的大1.9倍。 阶段A超级耀斑的测量很大程度上归功于与业余爱好者和专业人士的国际合作。 这与鸟类学的世界有相似之处，两者都通过国际观测交流在世界范围内发挥作用。 我描述了这些合作的概况，并阐述了我对天文学和鸟类学之间关系的看法，还展望了如何在这两个看似遥远的科学领域之间实现跨学科工作（摘录）。 显示英文摘要

摘要： In 2013, the method of determining mass ratios of dwarf novae using stage A superhumps (growing superhumps) was established. This method is a dynamical one in that it relies only on celestial mechanics. It is not dependent on an experimental calibration. Since then, more than 100 objects have been measured by this method. In this paper, I provide an updated description of the method. Comparisons with the results of the modern eclipse modeling method, which is considered to be the golden standard, have shown that these two methods agree very well and the stage A superhump method has been confirmed to be as accurate and as reliable as the modern eclipse modeling method. The number of the object by the former methods is now a few time those by the latter method, and the former is indispensable to study the terminal evolution of cataclysmic variables. I also showed that past studies by the other groups assumed incorrect fractional superhump excess relations, causing biases in discussing the evolution. I also derived a new experimental relation for stage B superhumps. The updated evolutionary track around the period minimum suggests that the angular momentum loss is 1.9 times larger than expected by gravitational wave radiation. The measurements of stage A superhumps greatly owe to international collaborations with amateurs and professionals. There is similarity with the world of ornithology in that both play a role in uniting the world via international exchanges of observations. I describe a summary of these collaborations and describe my thoughts about the relation between astronomy and ornithology, and give prospects how multidisciplinary works can be made possible between these seemingly distant fields of science (abridged).
