Stellar evolution models with overshooting based on 3-equation non-local theories I. Physical basis and the computation of the dissipation rate
F. Kupka, F. Ahlborn, A. Weiss
Context. Mixing by convective overshooting has long been suggested to play an important role for the amount of hydrogen available to nuclear burning in convective cores of stars. T…
Optimizing Higher-order Lagrangian Perturbation Theory for Cold Dark Matter Models
A. G. Weiss, S. Gottloeber, T. Buchert
We report on the performance of Lagrangian perturbation theory up to the second order for the standard cold dark matter (SCDM) and broken scale invariance (BSI) scenarios. We norma…
Optimizing Higher-Order Lagrangian Perturbation Theory for Standard CDM and BSI models
Arno G. Weiss, Stefan Gottloeber, Thomas Buchert
We investigate the performance of Lagrangian perturbation theory up to the second order for two scenarios of cosmological large-scale structure formation, SCDM (standard cold dark…
Optimized Lagrangian Approximations for Modelling Large--Scale Structure at Non--Linear Stages
T. Buchert, A. L. Melott, A. G. Weiss
Approximations to the exact solutions for gravitational instability in the expanding Universe are extremely useful for understanding the evolution of large--scale structure. We rep…
Optimized Lagrangian Approximations for Modelling Large--Scale Structure at Non--Linear Stages
T. Buchert, A. L. Melott, A. G. Weiss
We report on a series of tests of Newtonian Lagrangian perturbation schemes using N--body simulations for various power--spectra with scale--independent indices in the range t…
Testing Higher--Order Lagrangian Perturbation Theory Against Numerical Simulations -- 2. Hierarchical Models
A. L. Melott, T. Buchert, A. G. Weiß
We present results showing an improvement of the accuracy of perturbation theory as applied to cosmological structure formation for a useful range of scales. The Lagrangian theory…
