论文摘要
我们根据8 Gyr-Old Solar Twin Hip 102152进行了对未来太阳的旋转演化方案的详细分析。使用Harps High-Adcadence观察（和Tess Light Curves），我们分析了各种活动代理的调节（Ca II，Hi Balmer和Na I Lines），发现了强烈的旋转信号_ $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4 $ 1.4。在Ca II K线的情况下，因子} \ SIM70 $）。该值与关于太阳在主要序列结束时的平稳旋转演化的理论期望相匹配，从而验证了太阳时代后使用陀螺的使用。
We present a detailed analysis of the possible future Sun's rotational evolution scenario based on the 8 Gyr-old solar twin HIP 102152. Using HARPS high-cadence observations (and TESS light curves), we analyzed the modulation of a variety of activity proxies (Ca II, HI Balmer, and Na I lines), finding a strong rotational signal of 35.7 $\pm$ 1.4 days ($\log B_{\rm factor}\sim70$, in the case of Ca II K line). This value matches with the theoretical expectations regarding the smooth rotational evolution of the Sun towards the end of the main-sequence, validating the use of gyrochronology after solar age.
