Pulsations of delta Scuti stars
, 1989 A general review of the pulsating {delta} Scuti variables is given including the observed light curves and positions of the stars in the Hertzsprung-Russell diagram. Theoretical interpretations from evolution and pulsation calculations give their masses,

Discovery and Characterization of Three New High-amplitude δ Scuti Stars from TESS Observations
The Astrophysical JournalWe report the discovery and detailed analysis of three new high-amplitude δ Scuti (HADS) stars, TIC 408074920, TIC 189714989, and TIC 34137913, identified from Transiting Exoplanet Survey Satellite short-cadence observations.

Asteroseismology applied to constrain structure parameters of {\delta} Scuti stars
, 2023 Asteroseismology is a powerful tool to probe the structure of stars. Space-borne instruments like CoRoT, Kepler and TESS have observed the oscillations of numerous stars, among which {\delta} Scutis are particularly interesting owing to their fast ...

Amplitude Modulation of Pulsation Modes in Delta Scuti Stars [electronic resource] /
This outstanding thesis by Dominic Bowman provides a thorough investigation of long-standing questions as to whether amplitude modulation is astrophysical, whether it offers insights into pulsating stars, and whether simple beating of modes with stable ...

Multimode δ Sct stars from the Zwicky Transient Facility Survey
The Astrophysical Journal Supplement SeriesWe obtain the largest catalog of multimode δ Sct stars in the northern sky to date using the Zwicky Transient Facility (ZTF) Data Release 20. The catalog includes 2254 objects, of which 2181 are new to our study.

Stellar Variability toward the Galactic Open Cluster NGC 7209
The Astrophysical JournalWe present the analysis of stellar variability in an open cluster NGC 7209 using optical V -band CCD photometric observations. Out of 4499 stars in our study, we detected 284 candidate variables, including one identified previously.

Tidally Distorted Stars Are Triaxial Pulsators
The Astrophysical JournalStars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars using perturbation theory, accounting for the effects of the Coriolis force ...

The Astronomical JournalHIP 65426 hosts a young giant planet that has become the first exoplanet directly imaged with JWST. Using time-series photometry from the Transiting Exoplanet Survey Satellite (TESS), we classify HIP 65426 as a high-frequency δ Scuti pulsator with a ...

Period-Luminosity Relationship for $\delta$ Scuti Stars Revisited
The Gaia DR3 parallax approach was used to estimate the absolute parameters of 2375 Delta Scuti stars from the ASAS catalog. The selected stars have a variety of observational characteristics, with a higher than 80% probability of being Delta Scuti stars.
