PBjam: Asteroseismology for everyone

open access: yes, 2021
Asteroseismology is an exceptional tool for measuring fundamental stellar properties. The CoRoT, Kepler and TESS missions have observed thousands of stars that oscillate in a similar way as our Sun. This allows us to place tight constraints on their mass, radius and even age, which are important for understanding stellar structure and evolution ...

Progress in Global Helioseismology: A New Light on the Solar Modeling Problem and Its Implications for Solar-Like Stars

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Since the first observations of solar oscillations in 1960, helioseismology has probably been one of the most successful fields of astrophysics.

Asteroseismic Signature of a Large Active Region

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Axisymmetric magnetic activity on the Sun and sun-like stars increases the frequencies of the modes of acoustic oscillation. However, it is unclear how a corotating patch of activity affects the oscillations, since such a perturbation is unsteady in the ...

Asteroseismology with Small Telescopes [PDF]

open access: yesSymposium - International Astronomical Union, 1986
Study of the solar interior through analysis of solar oscillations, a field now referred to as helioseismology, has generated interest in the development of asteroseismology, the study of the interior of pulsating stars through the analysis of their oscillations.

White-Dwarf Asteroseismology With the Kepler Space Telescope

open access: yesFrontiers in Astronomy and Space Sciences, 2020
In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves

open access: yesFrontiers in Astronomy and Space Sciences, 2020
This paper aims at being a provocative guide to the future of asteroseismology from the perspective of the analysis of time series, where the fundamentals of harmonic analysis are subjected to stress tests.

Magnetar QPOs and Neutron Star Crust Elasticity

open access: yesUniverse
The crust region is a tiny fraction of neutron stars, but it has a variety of physical properties and plays an important role in astronomical observations. One of the properties characterizing the crust is elasticity. In this review, with the approach of

Asteroseismology with the WIRE satellite [PDF]

open access: yesCommunications in Asteroseismology, 2007
I give a summary of results from the WIRE satellite, which has been used to observe bright stars from 1999-2000 and 2003-2006. The WIRE targets are monitored for up to five weeks with a duty cycle of 30-40%. The aim has been to characterize the flux variation of stars across the Hertzsprung-Russell diagram.
