不会 因为一个天体要变成恒星，开始核聚变，要达到80个木星质量(大约)以上。既然是行星(其实HD 100546 b是褐矮星)，那肯定没达到这个标准，所以则是行星围绕恒星转！理解的不太准确。事实上，并不是行星绕着恒星转，而是彼此都是绕着系统质心转。大质量的行星的确会对恒星的运动造成影响，比如太阳系中...

We discuss from this point of view the recent discovery by COBE/FIRAS of a very cold Galactic dust component (4-7 K) which could correspond to a dominating gas mass component of the ISM, if interpreted as standard dust emission. Some of the proposed means could be applied to the well-...
