Abstract Type : Poster Abstract Category : Stars,ISM and the Galaxy Abstract : The maximum amplitude and frequency separations (∆ʋ) in the oscillation data of a stellar object are encoded with parameters that describe its structure and evolution. Fundamental properties like mass, radius, luminosity, age, effective temperature can be extracted using the existing relations between ∆ʋ and amplitude. Low amplitude is the signature for solar like oscillations. Such oscillation time series data can be obtained from the KEPLER and COROT space missions. Spectral analysis is performed to the oscillation data using a few mathematical techniques, to derive the ∆ʋ. The relations among the Astroseismic parameters will be discussed for better insights into stellar interiors. This work is an attempt to experiment with the oscillation data by conducting spectral analysis, in the hope of obtaining the said results using a certain mathematical technique and the results will be displayed in correlation to the available results to discuss the elegance of the technique. Key words: Asteroseismology, Kepler database, Fundamental properties, Oscillation mode frequencies, amplitudes. |
