dwarf galaxy
解釋
本銀河系吞噬的矮星系-
On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element
本文正是在銀河系化學演化的基礎上,利用銀河系的三成分( threezone ) (即暈、厚盤和薄盤)多相( multi - phase ) (氣體,分子云,大、小質量恆星以及剩餘物質)的化學演化的理論模型,通過與觀測約束(質量面密度、場星的年齡-金屬豐度關系、太陽附近g矮星金屬含量分佈函數、三成份的特徵量、元素的星系化學演化、超新星的爆炸率、內落速率等)的比較,來檢驗模型的合理性。 -
