查询词典 star-of-Bethlehem

Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。
