A study of the stellar photosphere-hydrogen ionization front interaction in $\delta$ Scuti stars [PDF]
Pulsating variable $\delta$ Scuti stars are intermediate-mass stars with masses in the range of $1-3$ $M_{\odot}$ and spectral types between $A2$ and $F2$.

Observations and a new interpretation for the Delta Scuti variable star VZ CANCRI
Extensive numbers of new photoelectric data have been collected and analyzed to investigate the modal behavior of VZ Cnc. Its previously observed periods yield a period ratio of 0.80 implying pulsation in the first and second radial overtones. Of the seventeen delta Scuti stars listed by Fitch and Sziedl which have well-determined periods, it is the ...

Close frequency pairs in Delta Scuti stars [PDF]
The majority of the well-studied δ Scuti stars shows frequency pairs in the power spectra with frequency separations less than 0.06 cd-1 ($0.7~\mu$Hz) as well as amplitude variability.

A CCD Search for Variable Stars in the Open Cluster NGC 6611 [PDF]
We present the results of the $UBVI_C$ variability survey in the young open cluster NGC 6611 based on observations obtained during 34 nights spanning one year. In total, we found 95 variable stars.

Asteroseismology Applied to Constrain Structure Parameters of δ Scuti Stars
Asteroseismology is a powerful tool to probe stellar structure. Spaceborne instruments like CoRoT, Kepler, and TESS have observed the oscillations of numerous stars, among which δ Scutis are particularly interesting, owing to their fast rotation and ...

A Systematic Search for New δ Scuti and γ Doradus Stars Using TESS Data [PDF]
Focusing on the discovery of new δ Scuti and γ Doradus stars, we analyzed the Transiting Exoplanet Survey Satellite (TESS) light curves for 193,940 A-F stars selected from four legacy catalogs—the Henry Draper Catalogue (HD), the ...

Quadratic Frequency Dispersion in the Oscillations of Intermediate-mass Stars
Asteroseismology, the study of stellar vibration, has met with great success, shedding light on stellar interior structure, rotation, and magnetism. Prominently known as δ Scutis, the intermediate-mass main-sequence oscillators that often exhibit rapid ...
