两颗巨行星的稳定宜居系统

Stable and habitable systems with two giant planets

Vera Dobos, Imre Nagy, Judit Orgoványi

摘要:

我们已经研究了类似于太阳系的行星系,它们是由三颗内部岩石行星(金星、地球、火星)和两颗外部气体巨星组成的。在不同质量气体行星的情况下,讨论了内行星轨道的稳定性。为了证明结果,制作了稳定性图,发现木星的质量可能是木星的四倍,土星的质量可能是土星的三倍,而内行星的轨道保持稳定。通过改变太阳的质量,也进行了类似的计算。在这种情况下,岩石行星的位置和液态水可居住区和紫外线宜居带的延伸进行了研究,为不同质量的太阳。结果发现,行星的轨道是稳定的值大于0.33 M_太阳,其中M_太阳是太阳的质量和在较低的太阳质量(约0.8 M_太阳),只有金星,但较高的质量值(约1.2 M_太阳),地球和火星都位于这两个宜居带。

英文摘要:

We have studied planetary systems which are similar to the Solar System and built up from three inner rocky planets (Venus, Earth, Mars) and two outer gas giants. The stability of the orbits of the inner planets is discussed in the cases of different masses of the gas planets. To demonstrate the results stability maps were made and it was found that Jupiter could be four times and Saturn could be three times more massive while the orbits of the inner planets stay stable. Similar calculations were made by changing the mass of the Sun. In this case the position of the rocky planets and the extension of the liquid water habitable and the UV habitable zones were studied for different masses of the Sun. It was found that the orbits of the planets were stable for values greater than 0.33 M_Sun where M_Sun is the mass of the Sun and at lower masses of the Sun (at about 0.8 M_Sun) only Venus, but for higher mass values (at about 1.2 M_Sun) Earth and also Mars are located in both habitable zones.
