White Dwarfs as Physics Laboratories: Lights and Shadows
Frontiers in Astronomy and Space Sciences, 2022 The evolution of white dwarfs is essentially a gravothermal process of cooling in which the basic ingredients for predicting their evolution are well identified, although not always well understood. There are two independent ways to test the cooling rate.

Asteroseismic inferences from the study of non-linearities in δ Sct stars
Frontiers in Astronomy and Space Sciences, 2022 Many pulsating star light curves must be interpreted strictly within the framework of a non-linear theory. The detection of non-linear interactions between pulsation modes has increased due to the ultra-precise photometric data provided by space missions.

Saturn's Rings as a Seismograph to Probe Saturn's Internal Structure
AGU Advances, Volume 1, Issue 2, June 2020., 2020 As it has already done for Earth, the Sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of events foreseen by only a few, observations of Saturn's rings by the Cassini spacecraft have rapidly broken ground on giant planet seismology. Gravity directly couples the planet'

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 ...

Asteroseismology and interferometry [PDF]
The Astronomy and Astrophysics Review, 2007 Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community ...

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

Pulsating stars and the Virtual Observatory
EPJ Web of Conferences, 2017 Virtual Observatory is one of the most used internet-based protocols in astronomy. It has become somewhat natural to find, manage, compare, visualize and download observations from very different archives of astronomical observations with no effort.

A Gravitational-Wave Perspective on Neutron-Star Seismology
Universe, 2021 We provide a bird’s-eye view of neutron-star seismology, which aims to probe the extreme physics associated with these objects, in the context of gravitational-wave astronomy.
