當我們的太陽演化為一顆紅巨星的時候,它會漲大到地球現時的位置而把地球吞噬。Our results show that, during the evolution of a binary system, the system widens as it loses mass, and the orbital period increase, while orbital eccentricity remains nearly constant, which can explain the distribution regulation of orbital elements of normal g - k giant and barium stars and the distribution character of the heavy - element abundances of barium stars
計算結果表明,隨著星風吸積過程的進行,在星風質量損失階段系統軌道半長軸將增大,導致軌道周期增大,而偏心率變化不大,由此可以解釋普通紅巨星雙星系統和鋇星系統的軌道根數的分佈規律和變化情況以及鋇星重元素豐度分佈特徵。" at present, ( the ) discovery is the only planetary system known to have survived its red - giant phase, " jonathan fortney, a nasa researcher, wrote in a commentary in nature
