The Transiting Exoplanet Survey Satellite (TESS) performs high-precision photometry over almost the whole sky primarily in search of exoplanet transits. It also provides...

The KEYSTONE project aims to enhance our understanding of solar-like oscillators by delivering a catalogue of global asteroseismic parameters ({Delta}{nu} and {nu}max) for 173...

Over the last few years, delta Scuti stars have been at the center of the attention of the asteroseismology community thanks to the derivation of seismic indices connected to...

Asteroseismic modelling of isolated stars presents significant challenges due to the difficulty in accurately determining stellar parameters, particularly the stellar age. These...

We present a new catalog of stars for which detected solar-like oscillations and magnetic activity measurements from chromospheric spectroscopic observations are both available....

The Transiting Exoplanet Survey Satellite (TESS) mission has provided photometric light curves for stars across nearly the entire sky. This allows for the application of...

We present results of a Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects observed in years 1 and 3 of the TESS mission,...

According to dynamo theory, stars with convective envelopes efficiently generate surface magnetic fields, which manifest as magnetic activity in the form of starspots, faculae,...

The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational variability in the OB star...

The nearby metal-poor giant HD122563 is an important astrophysical laboratory in which to test stellar atmospheric and interior physics. It is also a benchmark star for which to...

The standard cosmological model predicts that galaxies are built through hierarchical assembly on cosmological timescales. The Milky Way, like other disk galaxies, underwent...

Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star formation and...

Thanks to relatively firm mode identification, possible based only on period ratios, high-amplitude {delta} Scuti stars pulsating in at least three radial modes are promising...

Mass-loss remains a major uncertainty in stellar modelling. In low-mass stars, mass-loss is most significant on the red giant branch (RGB), and will impact the star's...

The detailed age-chemical abundance relations of stars measure time-dependent chemical evolution. These trends offer strong empirical constraints on nucleosynthetic processes,...

From sector 1-44 TESS observations, 19 new rapidly oscillating Ap (roAp) stars, 103 ostensibly non-peculiar stars with roAp-like frequencies, and 617 {delta} Scuti stars with...

We investigate the relationship between the asteroseismic indices and the physical quantities of 438 {delta} Scuti (DSCT) stars observed by the Transiting Exoplanet Survey...

Detailed understanding of stellar physics is essential towards a robust determination of stellar properties (e.g. radius, mass, and age). Among the vital input physics used in...

We report on the detection of pulsations of three pulsating subdwarf B stars observed by the Transiting Exoplanet Survey Satellite (TESS) satellite and our results of mode...

We provide three statistical model prescriptions for the bolometric corrections appropriate for B-type stars as a function of (i) T_eff_, (ii) T_eff_ and logg, and (iii) T_eff_,...
