Precise Asteroseismology of the High-amplitude Delta Scuti Star EH Librae, an AE UMa Analogue in the Hertzsprung Gap
Xiran Xie, Jianning Fu, Gang Meng +7
A subclass of intermediate mass variables Delta Scuti stars, known as High-amplitude Delta Scuti (HADS) stars, exhibits pronounced radial pulsations with high amplitudes. The groun…

Discovery of resonating integration modes in triple-mode high-amplitude Scuti stars: A new evolutionary phase indicator
Jia-Shu Niu, Hui-Fang Xue
High-amplitude Scuti stars (HADS) that pulsate in their first three radial modes are rare in current samples. Here, we analyse five such triple-mode HADS observed by the Trans…

Period Variation Rates of Four Radial Single-Mode High-Amplitude Delta Scuti Stars
Tian-Fang Ma, Jia-Shu Niu, Hui-Fang Xue
In this work, we present a study on the long time-scale period variations of four single-mode high-amplitude delta Scuti stars (HADS) via the classical analysis. The target H…
