Asteroseismology of Massive Stars : Some Words of Caution [PDF]
, 2014 Although playing a key role in the understanding of the supernova phenomenon, the evolution of massive stars still suffers from uncertainties in their structure, even during their "quiet" main sequence phase and later on during their subgiant and helium ...

Pulsation in Intermediate-Mass Stars
Frontiers in Astronomy and Space Sciences, 2018 A new perspective of pulsation in stars within the δ Scuti instability strip has recently emerged as a result of Kepler observations. The majority of stars within the instability strip do not pulsate and practically all δ Scuti stars contain low ...

Asteroseismology of binary stars and a compilation of core overshoot and rotational frequency values of OB stars [PDF]
, 2013 After a brief introduction into the asteroseismic modelling of stars, we provide a compilation of the current seismic estimates of the core overshooting parameter and of the rotational frequency of single and binary massive stars. These important stellar

On the Nature of the Core of α Centauri A: The Impact of the Metallicity Mixture
Frontiers in Astronomy and Space Sciences, 2019 Forward asteroseismic modeling plays an important role toward a complete understanding of the physics taking place in deep stellar interiors. With a dynamical mass in the range over which models develop convective cores while in the main sequence, the ...

The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS [PDF]
Astrophysical Journal, 2020 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 evolution models are used to determine the properties of the ensemble ...

Asteroseismology of Exoplanet Host Stars
, 2015 Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

Probing the interior physics of stars through asteroseismology [PDF]
, 2019 Years-long high-precision brightness measurements obtained with telescopes operating in space have become available for thousands of stars. Such data allowed us to measure the physics of stellar interiors via nonradial oscillations, opening a new avenue ...

A continuous population of variable stars up to about 1.5 mag above the horizontal branch?
, 2003 Increasing samples of pulsating variable stars populating the classical instability strip from the horizontal branch to a few magnitudes brighter are being found in several Local Group galaxies, irrespective of the galaxy morphological type.

Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi [PDF]
Nature Astronomy, 2020 Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies1. Although these accreted stellar populations can be forensically identified as kinematically distinct structures within the Galaxy, it is difficult in general

New ground-based observational methods and instrumentation for asteroseismology
, 2012 Space instrumentation like SOHO, MOST, CoRoT and Kepler has been and is being built to attain very high precision data to be used for asteroseismic analysis.
