While long-period variables (LPVs) have been extensively investigated, especially with MACHO and OGLE data for the Magellanic Clouds, there still exist open questions in their...

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...

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...

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...

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...

Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar...

Oscillation properties are usually measured by fitting symmetric Lorentzian profiles to the power spectra of Sun-like stars. However, the line profiles of solar oscillations...

TT Arietis (TT Ari) is a nova-like cataclysmic variable of the VY Scl subtype, with light curve variations on multiple timescales. Besides the superhump modulation,...

The formation history and evolution of the Milky Way through cosmological time is a complex field of research requiring the sampling of highly accurate stellar ages for all...

Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems contain- ing at least one oscillating component...

The main goal of this work is to date young open clusters using delta Sct stars. Seismic indices as the large separation and the frequency at maximum power can help to constrain...

The NASA K2 mission that succeeded the nominal Kepler mission observed several hundred thousand stars during its operations. While most of the stars were observed in single...

The space-borne missions CoRoT and Kepler opened up a new opportunity for better understanding stellar evolution by probing stellar interiors with unrivalled high-precision...

Measuring stellar inclinations is fundamental to understand planetary formation and dynamics as well as physical conditions during star formation. Oscillation spectra of red...
