We present the first asteroseismic results for δ Scuti and γ Doradus stars observed in
Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample …

Aims. We study the theoretical properties of the regular spacings found in the oscillation
spectra of δ Scuti stars. Methods. We performed a multivariable analysis that covered a wide …

We propose that TIC 448892817 is a double-mode high-amplitude δ Scuti star. The radial
modes detected in this star provide a unique opportunity to exploit asteroseismic techniques …

We have carried out an intensive survey of the northern region of the Fornax dwarf
spheroidal galaxy with the aim of detecting the galaxy's short-period pulsating stars (P< 0.25 …

We present the OGLE collection of delta Scuti stars in the Large Magellanic Cloud and in its
foreground. Our dataset encompasses a total of 15,256 objects, constituting the largest …

We analyse Kepler observations of the high-amplitude δ Scuti (HADS) star V2367 Cyg (KIC
9408694). The variations are dominated by a mode with frequency f 1= 5.6611 d− 1. Two …

We report CCD V and I time series photometry of the globular cluster NGC 5024 (M53). The
technique of difference image analysis has been used which enables photometric …

We analyse the pulsating behaviour of TIC 308396022, based on observations by the TESS
mission. The star is a high-amplitude δ Sct star that shows a very rich amplitude spectrum …

We present B, V, and I CCD light curves for 101 variable stars belonging to the globular
cluster NGC 2419, 60 of which are new discoveries, based on data sets obtained at the …

Stellar structure and evolution theory is one of the bases in modern astronomy. Stellar inner
structures and their evolutionary states can be precisely tested by asteroseismology, since …
