Atomic lines in spectra of RR Lyrae & RHB stars

We have derived relations between FWHMs and equivalent widths of metallic absorption lines in the spectra of RR Lyrae stars to estimate new upper limits on the axial equatorial...

本研究推导了天琴座RR型变星（RR Lyrae stars）光谱中金属吸收线的半高全宽（Full Width at Half Maximum，FWHM）与等效宽度（equivalent width）之间的关联关系，借此对赤道轴向的……估算出新的上限值。
