We present the first asteroseismic results for {delta} Scuti and {gamma} Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data...

The internal working of low-mass stars is of great significance to both the study of stellar structure and the history of the Milky Way. Asteroseismology has the power to...

Recently, by analysing the oscillation frequencies of 90 stars, Yildiz, Celik Orhan & Kayhan have shown that the reference frequencies ({nu}min0, {nu}min1, and {nu}min2)...

The stellar inclination angle - the angle between the rotation axis of a star and our line of sight - provides valuable information in many different areas, from the...

The recently published Kepler mission Data Release 25 (DR25) reported on ~197000 targets observed during the mission. Despite this, no wide search for red giants showing...

We study the fraction of stars in and around the {delta} Scuti instability strip that are pulsating, using Gaia DR2 parallaxes to derive precise luminosities. We classify a...

This paper presents spectroscopic and seismic analyses of two rare hybrid pulsating subdwarf B (sdB) stars, PG 0048+091 and PG 1315-123, which are dominated by pressure (p)-mode...

Deep learning in the form of 1D convolutional neural networks have previously been shown to be capable of efficiently classifying the evolutionary state of oscillating red...

Asteroseismology is witnessing a revolution, thanks to high-precise asteroseismic space data (MOST, COROT, Kepler, BRITE) and their large ground-based follow-up programs. Those...

Convective mixing in helium-core-burning (HeCB) stars is one of the outstanding issues in stellar modelling. The precise asteroseismic measurements of gravity-mode period...

In the power spectra of oscillating red giants, there are visually distinct features defining stars ascending the red giant branch from those that have commenced helium core...

We present an analysis of 168 oscillating red giants from NASA's Kepler mission that exhibit anomalous peaks in their Fourier amplitude spectra. These peaks result from...

Determining the ages of red-giant stars is a key problem in stellar astrophysics. One of the difficulties in this determination is to know the evolutionary state of the...

We report the discovery of a new subclass of double-mode RR Lyrae stars in the Large and Small Magellanic Clouds. The sample of 22 pulsating stars has been extracted from the...

We analysed solar-like oscillations in 1523 Kepler red giants which have previously been misclassified as subgiants, with predicted {nu}max values [based on the Kepler Input...

Asteroseismology is used to infer the interior physics of stars. The Kepler and TESS space missions have provided a vast data set of red-giant lightcurves, which may be used for...

This paper presents a correction to the scaling relations for red giant stars using model-based masses and radii. We measure radial-mode frequencies from Kepler observations for...

We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1-C8 and C10-C18. We provide asteroseismic radius and mass...

Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160...

In this paper, the pulsation behavior of high-amplitude {delta} Scuti star GSC 4552-1498 was analyzed. Using the high-precision photometric data from the Transiting Exoplanet...
