摘要

介绍了脉动波形、幅度、周期和周期变化率的相干测量策略，其中“相干”意味着模型恒星确实在脉动，在没有二元效应的脉动和没有脉动的二元效应之间没有人为的交替。更先进的日食双星(EB)光曲线模型的能力已经具备，例如多波段数据和径向速度的同时解决方案，包括潮汐、相互照射和适当的数据点加权。对algoltype EB V1352 Tau的应用显示了可能性。

Binary star analysis with intrinsic pulsation

Strategies are introduced for coherent measurement of pulsational waveforms, amplitudes, periods, and period change rates, where ‘coherent’ means that the model stars indeed pulsate, with no artificial alternation between pulsation without binary effects and binary effects without pulsation. Capabilities of the more advanced eclipsing binary (EB) light curve models are in place, such as simultaneous solutions of multiband data and radial velocities with inclusion of tides, mutual irradiation, and proper datapoint weighting. An application to the Algol-type EB V1352 Tau exhibits possibilities.
