Mass – Radius Relationship in Extrasolar Planets

Abstract

The increasing number of Extrasolar planets observed in the last years makes important to define, as soon as possible, a mass – radius relationship, and so, we adjusted an planetary constitution independent experimental equation. Using the latest database of Extrasolar planets, a bi-logarithmic graphic was plotted that represents the mass - radius relationship where we adjusted a polynomial equation, which better suited the sample of Extrasolar planets at current time.
