dc.descriptionFor spherically symmetric relativistic perfect fluid models, the well-known Buchdahl inequality provides the bound $2 M/R \leq 8/9$, where $R$ denotes the surface radius and $M$ the total mass of a solution. By assuming that the ratio $p/ρ$ be bounded, where $p$ is the pressure, $ρ$ the density of solutions, we prove a sharper inequality of the same type, which depends on the actual bound imposed on $p/ρ$. As a special case, when we assume the dominant energy condition $p/ρ\leq 1$, we obtain $2 M/R \leq 6/7$.
