Detailed theoretical models for extra - solar planet - host stars

In this paper we analyse and discuss the HR Diagram position of two extra-solar planet-host stars HD37124 and HD46375 by means of theoretical stellar evolution models. This work was triggered by the results obtained by Laws et al. (2003) who found that these stars were in contradiction to the expectation based on their high metallicity. Fixing the age of both stars with the value based on their...

theoretical models in welfare economics

the present essay intend to intoduce some vital established economic models of social welfare as welfare criticize and evaluate their capability and their explicative nature . the cotent is totally theoretical and therefore the evaluation will be done through hypothetical and abstract values and criteria . particularly the essay tries to go beyond exact socio - economic welfare models and to fi...

Standard Solar Models

A lot of progress has been made in understanding the robustness of solar model predictions since Neutrino 96 [1]. In this talk, I will first summarize the new ingredients and then give the current best-estimates. Then I will discuss the uncertainties in the predictions. Many of the results given here are adopted from the recent BP98 paper [2]. As we shall see in Section 3, there is excellent ag...
