Constraining fundamental stellar parameters using seismology
We apply the Levenberg-Marquardt minimization algorithm to seismic and classical observables of the αCen binary system in order to derive the fundamental parameters of αCenA+B, and to analyze the dependence of these parameters on the chosen observables, on their uncertainty, and on the physics used in stellar modelling. The seismological data are those by Bouchy & Carrier (2002) for αCen A, and...
متن کاملYrec: the Yale Rotating Stellar Evolution Code Non-rotating Version, Seismology Applications
The stellar evolution code YREC is outlined with emphasis on its applications to helioand asteroseismology. The procedure for calculating calibrated solar and stellar models is described. Other features of the code such as a non-local treatment of convective core overshoot, and the implementation of a parametrized description of turbulence in stellar models, are considered in some detail. The c...
متن کاملGPS seismology
GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...
متن کاملStatistical Seismology
Stochastic models with an increasing component of physical reasoning have been slowly gaining acceptance over the last two decades. The subject of statistical seismology aims to bridge the gap between physics-based models without statistics, and statistics-based models without physics. This volume, which is based largely on papers presented at the 3rd International Workshop on Statistical Seism...
متن کاملSeismology and CTBT Verification
It is well-known that the design and production of nuclear weapons required major efforts in scientific research and engineering, with a supporting infrastructure of weapons laboratories. Less well-known, is that scientific research and development have also played an important role in nuclear arms control. In this paper, my purpose is to explain the role of seismology in treaty verification; t...
