In the study of planetary habitability and terrestrial atmospheric evolution, the divergence of surface conditions for Venus and Earth remains an area of active research. Among the intrinsic and external influences on the Venusian climate history are orbital changes due to giant planet migration that have both variable incident flux and tidal heating consequences. Here, we present the results of a study that explores the effect of Jupiter’s location on the orbital parameters of Venus and subsequent potential water-loss scenarios. Our dynamical simulations show that various scenarios of Jovian migration could have resulted in orbital eccentricities for Venus as high as 0.31. We quantify the implications of the increased eccentricity, including tidal energy, surface energy flux, and the variable insolation flux expected from the faint young Sun. The tidal circularization timescale calculations demonstrate that a relatively high tidal dissipation factor is required to reduce the ec...

木星的迁移会加速金星的大气演化吗？

在研究行星的可居住性和地球大气演化时，金星和地球表面条件的差异仍然是活跃的研究领域。在金星气候历史的内在和外在影响中，有由于巨大行星迁移引起的轨道变化，这既有可变的入射通量又有潮汐加热的后果。在这里，我们提出了一项研究的结果，该研究探讨了木星的位置对金星的轨道参数和随后的潜在失水情景的影响。我们的动力学模拟表明，木星迁移的各种情况可能导致金星的轨道偏心率高达0.31。我们量化了偏心率增加的影响，包括潮汐能，表面能通量以及昏暗的年轻太阳预期的可变日照通量。
