+ | |||
+ | Compute realistic models of rotating stars deformed by the centrifugal force and provide a grid of models with seismic indices. | ||
+ | |||
+ | |||
+ | === Tasks === | ||
+ | |||
+ | |||
+ | * Compute static 2D models that fit constrains on classical stellar global parameters and seismic indices | ||
+ | |||
+ | |||
+ | As 2D evolution codes do not yet exist, the idea is to derive a grid of 2D models from a grid of 1D evolution models (that take into account rotation effect through 1D modelling) and then to search from this grid the 2D models that best fit the constrains (as the open source tool TOUCAN already does from a 1D model grid). An algorithm to obtain a deformed 2D model from a 1D model has been proposed by I. Roxburgh (2006) and implemented once by R. Ouazzani ([[http:// | ||

+ | * An open source version of the TOP code | ||
+ | |||
+ | |||
+ | The TOP code (Reese et al., 2006, Reese et al. 2009, Reese 2013) has been developped by D. Reese during his Ph.D in Toulouse and has maintained and improved by him since. It is the first code to accurately | ||

+ | === Deliverables === | ||
+ | |||
+ | |||
+ | * Grid of 2D models including basic seismic indices | ||
+ | * Tool to compute a 2D centrifugally deformed model fitting a given set of stellar and seismic parameters | ||
+ | * Open source code to compute oscillation modes of rapidly rotating stars | ||
