双星系统宜居带的计算II:P型双星

Calculating the Habitable Zone of Binary Star Systems II: P-Type Binaries

N. Haghighipour, L. Kaltenegger

摘要:

我们已经开发了一个全面的方法来计算环联HZ在行星托管P型双星系统。我们提出了一个一般的形式主义确定的贡献,每一个恒星的二到接收的总流量在顶部的大气层的类地行星,并使用太阳的HZ计算的HZ的内部和外部边界的位置周围的双星系统。我们应用我们的计算开普勒的目前已知的环双星行星系,并显示合并的恒星通量,确定其HZ的边界。我们还表明,在P-型系统的HZ是动态的,并取决于光度的双星,他们的光谱型,和二进制偏心率,其边界变化的恒星进行轨道运动的二进制。我们提出了我们的计算的细节,并讨论了结果的影响。

英文摘要:

We have developed a comprehensive methodology for calculating the circumbinary HZ in planet-hosting P-type binary star systems. We present a general formalism for determining the contribution of each star of the binary to the total flux received at the top of the atmosphere of an Earth-like planet, and use the Sun's HZ to calculate the locations of the inner and outer boundaries of the HZ around a binary star system. We apply our calculations to the Kepler's currently known circumbinary planetary system and show the combined stellar flux that determines the boundaries of their HZs. We also show that the HZ in P-type systems is dynamic and depending on the luminosity of the binary stars, their spectral types, and the binary eccentricity, its boundaries vary as the stars of the binary undergo their orbital motion. We present the details of our calculations and discuss the implications of the results.
