Period-luminosity and period-luminosity-metallicity relation for $\hat{I}´$ Scuti Stars

Yan-qi Liu, Xiao-dian Chen, Shu Wang +3

$\hat{I}´$ Scuti ($\hat{I}´$ Sct) stars are potential distance tracers for studying the Milky Way structure. We conduct a comprehensive analysis of the period-luminosity (PL) and period-lumino…
