【摘要】:正至今已發(fā)現(xiàn)550多顆太陽系外的行星.其中許多是所謂的熱木星,因?yàn)檫@些行星的質(zhì)量與木星相近,軌道與它們的主恒星非?拷.但是天文學(xué)家們不明白為什么這些外行星的四分之一都繞著與它們恒星的自旋反方向的軌道運(yùn)行.這與我們的太陽系不同,太陽系中的行星都繞著與太陽自旋相同的方向做軌道轉(zhuǎn)動(dòng).
[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.
