Abundance analysis of seven delta Scuti stars
, 2008 Context: The current knowledge of the abundance pattern in delta Scuti stars is based on analysis of just a few field stars. Aims: We aim to determine the general chemical properties of the atmospheres of delta Scuti stars based on a statistically ...

Observations and a new interpretation for the Delta Scuti variable star VZ CANCRI
The Astrophysical Journal, 1984 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 ...

The Astrophysical Journal, 2023 A star’s rotation rate is difficult to estimate without surface inhomogeneities such as dark or bright spots. This paper presents asteroseismic results to determine the rotation rates of δ Sct-type pulsating primary stars in two eclipsing binary systems,

Solar-like oscillations in Delta Scuti stars [PDF]
, 2011 Diese Dissertation befasst sich mit der Suche nach sonnenähnlichen Oszillationen in Delta Scuti Sternen. Theoretische Modelle deuten darauf hin, dass die Konvektion in den äußeren Schichten dieser Sterne noch effektiv genug ist, um diese Art Pulsationen

The pulsation of Delta Scuti stars [PDF]
, 2014 A theoretical study of the pulsation of Delta Scuti stars is presented. A modified Henyey code is used to produce a grid of evolutionary models of population I composition, spanning the area of the Instability Strip on and near the Main Sequence ...

Oscillation frequencies of moderately rotating delta scuti stars: asymmetric mode splittings due to non-spherical distortion [PDF]
We find that the observed pressure-mode rotational splittings of slowly/moderately rotating Scuti stars and Cephei stars mostly have a positive asymmetry.

Journal of the National Science Foundation of Sri Lanka, 2020 Asteroseismology is the science that deals with the oscillations in the stars with the goal of understanding the stellar structure. In this study, photometric data of Kepler mission have been used for the asteroseismic study of Delta Scuti type pulsating stars. The light curve analysis of three Delta Scuti stars observed by Kepler mission is presented.

A magnetic study of the δ Scuti variable HD 21190 and the close solar-type background star CPD −83°64B [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 HD 21190 is a known $\delta$ Scuti star showing Ap star characteristics and a variability period of 3.6 h discovered by the Hipparcos mission. Using Gaia DR1 data for an astrometric analysis, it was recently suggested that HD 21190 forms a physical binary system with the companion CPD -83$^{\circ}$ 64B.
