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

Inverse Problems in Asteroseismology [PDF]
, 2022 Asteroseismology allows us to probe the internal structure of stars through their global modes of oscillation. Thanks to missions such as the NASA Kepler space observatory, we now have high-quality asteroseismic data for nearly 100 solar-type stars. In this thesis, new techniques to measure the ages, masses, and radii of stars are presented, as well as

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 ...

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.

The Quest for Pulsating M Dwarf Stars
Frontiers in Astronomy and Space Sciences, 2019 Recent fully non-adiabatic theoretical studies of M dwarf models show that they have the potential to excite radial, and low-order, low-degree non-radial modes, as well as solar-like oscillations, due to models being completely convective or having large

Inversions of Stellar Structure From Asteroseismic Data
Frontiers in Astronomy and Space Sciences, 2022 The advent of space-based photometry missions in the early 21st century enabled the application to asteroseismic data of advanced inference techniques until then restricted to the field of helioseismology.

Asteroseismology of Pulsating Stars [PDF]
Journal of Astrophysics and Astronomy, 2015 The success of helioseismology is due to its capability of measuring p-mode oscillations in the Sun. This allows us to extract informations on the internal structure and rotation of the Sun from the surface to the core. Similarly, asteroseismology is the study of the internal structure of the stars as derived from stellar oscillations.

Current issues in asteroseismology
Journal of Physics: Conference Series, 2008 In this contribution we briefly review some of the current issues and promises for the future by asteroseismology. We are entering a new phase in this field driven by the wealth of data that has been collected and data that will soon be available for asteroseismology across the HR Diagram.
