CALIFA galaxies observational hints

According to numerical simulations, stars are not always kept at their birth galactocentric distances but migrate. The importance of this radial migration in shaping galactic...数值模拟表明，恒星并非始终停留在其诞生时的银心距（galactocentric distance）位置，而是会发生径向迁移（radial migration）。该径向迁移在塑造星系结构过程中的重要性……
