摘要:

我们使用佐治亚州立大学的CHARA阵列干涉仪直接测量了11颗系外行星宿主星的角直径,并计算了它们的线性半径和有效温度。样本倾向于演化或进化的恒星,包括一颗矮星,四颗亚巨星和六颗巨星。然后,我们估计质量和年龄的恒星使用我们的有效温度结合金属丰度测量文献。

英文摘要:

We directly measured the angular diameters for 11 exoplanet host stars using Georgia State University's CHARA Array interferometer and calculated their linear radii and effective temperatures. The sample tends towards evolving or evolved stars and includes one dwarf, four subgiants, and six giants. We then estimated masses and ages for the stars using our effective temperatures combined with metallicity measurements from the literature.
