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.

The pulsation of Delta Scuti stars [PDF]
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 ...

USING CONSUMER-GRADE DSLR CAMERA AND SMALL TELESCOPE TO FIND NEW VARIABLE STARS
Twenty-seven new variable stars were found in DSLR images captured from October 2017 to June 2019. All images were taken using unmod- i?ed Canon EOS 600D DSLR attached to a Sky- watcher 150/750 Newtonian on a motorized equato- rial mount.

The GFCAT: A Catalog of Ultraviolet Variables Observed by GALEX with Subminute Resolution
We have performed the first systematic search of the full Galaxy Evolution Explorer (GALEX) data archive for astrophysical variability on timescales of seconds to minutes by rebinning data across the whole mission to 30 s time resolution.

A magnetic study of the δ Scuti variable HD 21190 and the close solar-type background star CPD −83°64B [PDF]
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.

Search for variable stars in the open cluster NGC 2539 [PDF]
We present UBVI absolute and V-band time-series CCD photometric results for the intermediate-age open cluster NGC 2539. From the empirical zero-age main sequence and theoretical isochrone fitting in color-color and color-magnitude diagrams, we estimated ...

Eight Phase-step δ Scuti Variables in TESS Data
Analysis of the previously classified delta Scuti variable star MW Camelopardalis using data from the Transiting Exoplanet Survey Satellite sparked a deeper inquiry due to unexpected patterns within the target’s observed − calculated ( O − C ) diagram ...
