One explanation is that HIP 13044 swallowed its inner planets during the red giant phase, which would make the star spin more quickly.
一种解释是HIP 13044在红巨星阶段吞噬了它的一些带内行星,这可能使它自转得更快。
Even though this would help Earth to survive the sun's red giant phase, its ultimate fate is probably sealed.
即使这样有助于地球度过太阳的红巨星阶段,但它的最终命运仍然未卜。
First, it's really old - past the Red Giant phase, when stars balloon in size and swallow up planets in close orbits.
首先,它非常非常老了——它经历过红巨星阶段,这一阶段的恒星会急剧膨胀,吞噬在临近轨道运行的行星。
