Stellar hydrodynamics caught in the act: Asteroseismology with CoRoT and Kepler

, 2011
Asteroseismic investigations, particularly based on data on stellar oscillations from the CoRoT and Kepler space missions, are providing unique possibilities for investigating the properties of stellar interiors.

Asteroseismology of red giants & galactic archaeology

, 2017
Red-giant stars are low- to intermediate-mass ($M \lesssim 10$~M$_{\odot}$) stars that have exhausted hydrogen in the core. These extended, cool and hence red stars are key targets for stellar evolution studies as well as galactic studies for several ...

Tracing early stellar evolution with asteroseismology: pre-main sequence stars in NGC 2264 [PDF]

, 2014
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 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.

Scaled oscillation frequencies and echelle diagrams as a tool for comparative asteroseismology

, 2010
We describe a method for comparing the frequency spectra of oscillating stars. We focus on solar-like oscillations, in which mode frequencies generally follow a regular pattern.

Stellar ages from asteroseismology [PDF]

, 2008
Asteroseismology provides powerful means to probe stellar interiors. The oscillations frequencies are closely related to stellar interior properties via the density and sound speed profiles.

Asteroseismology with Small Telescopes [PDF]

Symposium - 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.
