M31中恒星径向混合的检验

Test for Radial Mixing of Stars in M31

Andrew Gould, Hans-Walter Rix

摘要:

有效的径向迁移和混合的轨道在整个恒星盘已明确建立在银河系,但没有在任何其他星系。我们展示了如何在M31中使用现有数据和现成设施的组合来测量(或强烈约束)这种径向混合。

英文摘要:

Effective radial migration and mixing of orbits throughout the stellar disk has been definitively established in the Milky Way, but not in any other galaxy. We show how such radial mixing can be measured (or strongly constrained) in M31 using a combination of existing data and readily available facilities.
