Asteroseismology of High-Mass Stars: New Insights of Stellar Interiors With Space Telescopes [PDF]
Frontiers in Astronomy and Space Sciences, 2020 Massive stars are important metal factories in the Universe. They have short and energetic lives, and many of them inevitably explode as a supernova and become a neutron star or black hole.

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 with fundamental modes from compact binary inspirals. [PDF]
Nat Commun, 2020 Gravitational waves (GWs) from binary neutron stars encode unique information about ultra-dense matter through characterisic signatures associated with a variety of phenomena including tidal effects during the inspiral.

Asteroseismology of Compact Stars
UniverseCompact stars have been perceived as natural laboratories of matter at an extremely high density. The uncertainties of the equation of state (EOS) of matter can be constrained by observing compact stars.

Tracing early stellar evolution with asteroseismology: pre-main sequence stars in NGC 2264 [PDF]
EPJ Web of Conferences, 2015 Asteroseismology has been proven to be a successful tool to unravel details of the internal structure for different types of stars in various stages of their main sequence and post-main sequence evolution.

A calibration point for stellar evolution from massive star asteroseismology [PDF]
Nature Astronomy, 2023 Transiting Exoplanet Survey Satellite data of the massive star HD 192575 reveal pulsation frequencies that allow the inference of its convective core mass and interior rotation profile, thus providing a calibration point for interior chemical and angular

Internal magnetic fields in 13 red giants detected by asteroseismology [PDF]
Astronomy & Astrophysics, 2023 While surface fields have been measured for stars across the HR diagram, internal magnetic fields remain largely unknown. The recent seismic detection of magnetic fields in the cores of several Kepler red giants has opened a new avenue to understand ...

The Potential of Asteroseismology to Resolve the Blue Supergiant Problem [PDF]
Astrophysical Journal Letters, 2023 Despite major progress in our understanding of massive stars, concerning discrepancies still remain between observations and theory. Most notable are the numerous stars observed beyond the theoretical main sequence, an evolutionary phase expected to be ...

Giant Planet Engulfment by Evolved Giant Stars: Light Curves, Asteroseismology, and Survivability [PDF]
Astrophysical Journal, 2023 About ten percent of Sun-like (1–2 M ⊙) stars will engulf a 1–10 M J planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution.

Asteroseismology using quadrupolar f -modes revisited: Breaking of universal relationships in the slow hadron-quark conversion scenario [PDF]
Physical Review D, 2023 In this work, we consider polar perturbations and we calculate the frequency and damping time of the quadrupolar fundamental f -mode of compact objects, constructed using a wide range of model-independent hybrid equations of state that include quark ...
