摘要

本文报道了开普勒区65颗恒星的uvby−Hβ光电光度测量结果，重点研究了δ Scuti、γ Doradus和混合型恒星。详细描述了用于推导Strömgren指数和颜色V，（b−y）， m1， c1和Hβ的观察程序和方法。我们在样本中识别矮星和巨人，并报告它们的物理参数。其中47颗恒星的Teff和log由我们的指数确定，已由Uytterhoeven et al.（2011）报道，其余恒星的参数由本文提供。此外，通过分析所有可用的开普勒和TESS光曲线，我们重新审视了这些恒星的变异性分类，并确认了之前研究中分配的大部分脉动分类。

uvby−Hβ Photoelectric photometry of 65 A/F-type candidate stars in the Kepler field: Observations, stellar parameters and variability analysis

We present the results of

u v b y - H_{β}

photoelectric photometry for 65 stars in the Kepler field, focusing on the study of

δ

Scuti,

γ

Doradus, and hybrid-type stars. The observing procedures and methodology used to derive the Strömgren indices and colors

V

(b - y)

m_{1}

c_{1}

, and

H_{β}

are described in detail. We identify dwarfs and giants within the sample and report their physical parameters. For 47 stars,

T_{eff}

and

log g

determined from our indices were previously reported by Uytterhoeven et al. (2011), while for the remaining stars, these parameters are provided in this work. Additionally, we revisit the variability classifications of these stars by analyzing all available Kepler and TESS light curves and confirm most of the pulsation classifications assigned in previous studies.
