Abstract
Theories with varying gravitational constant G have been studied long time ago. Among them, the most promising candidates as alternatives of the stand ard general relativity are known as scalar-tensor theories. They provide co nsistent descriptions of the observed universe and arise as the low energy limit of several pictures of unified interactions. Therefore, an increasing interest on the astrophysical consequences of such theories has been spark ed over the last few years. In this letter we comment on two methodological approaches to study evolution of astrophysical objects within a varying-G theory, and the particular results we have obtained for boson and white dwa rf stars.
