Curvelet analysis of asteroseismic data I: Method description and application to simulated sun-like stars
Context. The detection and identification of oscillation modes (in terms of their l, m and successive n) is a great challenge for present and future asteroseismic space missions. The “peak tagging” is an important step in the analysis of these data to provide estimations of stellar oscillation mode parameters, i.e., frequencies, rotation rates, and further studies on the stellar structure. Aims...
متن کاملOn Inverting Asteroseismic Data
Some issues of inverting asteroseismic frequency data are discussed, including the use of model calibration and linearized inversion. An illustrative inversion of artiicial data for solar-type stars, using least-squares tting of a small set of basis functions, is presented. A few details of kernel construction are also given.
متن کاملDetermination of Stellar Radii from Asteroseismic Data
The NASA Kepler mission is designed to find planets through transits. Accurate and precise radii of the detected planets depend on knowing the radius of the host star accurately, which is difficult unless the temperature and luminosity of the star are known precisely. Kepler, however, has an asteroseismology programme that will provide seismic variables that can characterise stellar radii easil...
متن کاملGaussian Process Modelling of Asteroseismic Data
The measured properties of stellar oscillations can provide powerful constraints on the internal structure and composition of stars. To begin this process, oscillation frequencies must be extracted from the observational data, typically time series of the star’s brightness or radial velocity. In this paper, a probabilistic model is introduced for inferring the frequencies and amplitudes of stel...
