Line broadening parameters in 22 RR Lyrae

We have investigated the absorption shapes of atomic lines and H{alpha} in RR-Lyrae stars. We used the database of high-resolution spectra gathered with the Las Campanas...

本研究针对天琴座RR型变星（RR Lyrae stars）中的原子谱线与氢α（Hα）谱线的吸收轮廓开展了探究。我们采用了由拉斯坎帕纳斯（Las Campanas）采集的高分辨率光谱数据库。
