使用SBF方法的距离和恒星星族属性

Distances and Stellar Population properties using the SBF method

Michele Cantiello, Gabriella Raimondo, Enzo Brocato, Ilaria Biscardi

摘要:

本文介绍了利用SBF技术研究星系的恒星星族性质和距离的一些结果。这里总结的应用表明,表面亮度波动(SBF)方法能够i)提供精确的距离解决和未解决的恒星系统从~10 Kpc到~150 Mpc,和ii)可靠地约束的物理性质(如年龄和金属丰度)的未解决的恒星系统。

英文摘要:

We present some results on the study of stellar population properties and distances of galaxies using the SBF technique. The applications summarized here show that the Surface Brightness Fluctuations (SBF) method is able to i) provide accurate distances of resolved and unresolved stellar systems from ~10 Kpc to ~150 Mpc, and ii) to reliably constrain the physical properties (e.g. age and metallicity) of unresolved stellar systems.
