大质量伙伴反转热木星
发布时间:2019-04-29 18:25
【摘要】:正至今已发现550多颗太阳系外的行星.其中许多是所谓的热木星,因为这些行星的质量与木星相近,轨道与它们的主恒星非常靠近.但是天文学家们不明白为什么这些外行星的四分之一都绕着与它们恒星的自旋反方向的轨道运行.这与我们的太阳系不同,太阳系中的行星都绕着与太阳自旋相同的方向做轨道转动.
[Abstract]:More than 550 extrasolar planets have been discovered so far. Many of them are so-called hot Jupiter, because these planets are close to Jupiter in mass and orbit is very close to their main stars. But astronomers do not understand why 1/4 of these exoplanets orbit opposite the spin of their stars. Unlike our solar system, planets in the solar system orbit in the same direction as the sun.
