發(fā)布時間:2018-12-11 03:14
【摘要】:正Algol型雙星是雙星的一種,其獨特的半接結構使它擁有豐富的物理現(xiàn)象,包括嚴重畸變的充滿子星、強磁活動現(xiàn)象,物質轉移的各種形式,完全迥異于單星的演化狀態(tài)和特有的形成歷史.本文對雙星光變曲線的基礎物理做了介紹,同時介紹了歷史上的各個模型或程序.展示了各個物理參數(shù)對光變曲線的影響,包括傾角、溫度、金屬豐度、表面重力加速度、第3光、半徑、軌道橢率和軌道近點角等.根據(jù)已有星表統(tǒng)計了Algol型雙星的性質,并對3顆樣本星進行了具體的觀測和分析,結果如下:
[Abstract]:Positive Algol binaries are one of the binary stars. Their unique semi-junction structure makes them rich in physical phenomena, including seriously distorted filling stars, strong magnetic activity, and various forms of mass transfer. It is completely different from the evolution state and unique formation history of single star. In this paper, the basic physics of double star light variation curve is introduced, and various models or programs in history are also introduced. The effects of various physical parameters on the photovariation curves are shown, including inclination, temperature, metal abundance, surface gravity acceleration, third light, radius, orbital ellipticity and orbital near-point angle, etc. The properties of Algol binary stars are statistically analyzed according to the existing catalogs, and three sample stars are observed and analyzed in detail. The results are as follows:
