TL;DR
This paper develops an updated pulsational model for BL Her stars, a type of Population II Cepheids with periods under 8 days, covering a broad range of stellar parameters.
Contribution
It provides a new, homogeneous pulsational scenario specifically tailored for BL Her stars, improving understanding of their behavior.
Findings
Enhanced pulsational models for BL Her stars.
Better agreement with observed stellar properties.
Refined predictions of pulsation periods and amplitudes.
Abstract
We present an updated and homogeneous pulsational scenario for a wide range of stellar parameters typical of BL Her stars i.e., Population II Cepheids with periods shorter than 8 days.
