Using Asteroseismology to Calibrate the Physical Parameters of Confirmed Exoplanets and Their Evolved Host Stars [PDF]
Astronomical JournalAsteroseismology offers a profound window into stellar interiors and has emerged as a pivotal technique in exoplanetary research. This study harnesses the Transiting Exoplanet Survey Satellite observations to reveal, for the first time, the asteroseismic

A review on Asteroseismology [PDF]
, 2016 Over the last decade, thanks to the successful space missions launched to detect stellar pulsations, Asteroseismology has produced an extraordinary revolution in astrophysics, unveiling a wealth of results on structural properties of stars over a large ...

TESS Data for Asteroseismology: Light-curve Systematics Correction [PDF]
Astrophysical Journal Supplement Series, 2021 Data from the Transiting Exoplanet Survey Satellite (TESS) have produced of the order of one million light curves at cadences of 120 s and especially 1800 s for every ∼27 day observing sector during its two-year nominal mission.

Pulsating stars harbouring planets
EPJ Web of Conferences, 2013 Why bother with asteroseismology while studying exoplanets? There are several answers to this question. Asteroseismology and exoplanetary sciences have much in common and the synergy between the two opens up new aspects in both fields.

Gravitational wave asteroseismology of dark matter hadronic stars [PDF]
Physical Review DThe influence of the dark matter mass~($M_{\chi}$) and the Fermi momentum~($k_{F}^{\dm}$) on the $f_0$-mode oscillation frequency, damping time parameter, and tidal deformability of hadronic stars are studied by employing a numerical integration of ...

Asteroseismology of the double-radial mode δ Scuti star BP Pegasi [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Using the ASAS data, we determine the pulsational frequencies of the high-amplitude δ Sct star BP Pegasi. The analysis revealed only the two known, independent frequencies that we use to perform the seismic analysis of the star.

Asteroseismology and magnetic cycles [PDF]
Astronomische Nachrichten, 2012 AbstractSmall cyclic variations in the frequencies of acoustic modes are expected to be a common phenomenon in solar‐like pulsators, as a result of stellar magnetic activity cycles. The frequency variations observed throughout the solar and stellar cycles contain information about structural changes that take place inside the stars as well as about ...

, 2013 Asteroseismology is the determination of the interior structures of stars by using their oscillations as seismic waves. Simple explanations of the astrophysical background and some basic theoretical considerations needed in this rapidly evolving field are followed by introductions to the most important concepts and methods on the basis of example ...

Modelling Neutron-Star Ocean Dynamics
Universe, 2023 We revisit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understanding of ocean modes relies heavily on the traditional approximation commonly

Asteroseismology of solar-type stars [PDF]
Living Reviews in Solar Physics, 2019 Until the last few decades, investigations of stellar interiors had been restricted to theoretical studies only constrained by observations of their global properties and external characteristics.
