Statistical analysis of asteroseismic indices and stellar parameters of TESS-observed Scuti stars
C. Lv, A. Esamdin, A. Hasanzadeh +4
We analyze the statistical properties and asteroseismic indices of delta Scuti stars observed during TESS Cycle 4. Using 2 minute cadence photometry and Fourier analysis, we identi…
Frequency analysis of KIC 1573174 : shedding light on the nature of HADS stars
Chenglong Lv, Ali Esamdin, Javier Pascual-Granado +2
We propose that KIC 1573174 is a quadruple-mode Scuti star with pulsation amplitudes between those of the HADS (high-amplitude Delta Scuti star) group and average low-amplitude…
Observational - relation for Sct stars using eclipsing binaries and space photometry
Antonio García Hernández, Susana Martín-Ruiz, Mário J. P. F. G. Monteiro +4
Delta Scuti ( Sct) stars are intermediate-mass pulsators, whose intrinsic oscillations have been studied for decades. However, modelling their pulsations remains a real theoreti…
