| Resumen en inglés | A model for low mass compact objects with compactness ratio u ≤ 0.06093 is presented here. Density, pressure and sound speed are regular and monotonic decreasing functions. The change between the central density ρc and the density on the surface ρb is lower than 3.94% and the maximum change occurs for the biggest compactness, i.e. ρc = 1.0394ρb. This allows us to apply this model for the case of compact stars in which the density variation is very small. In particular, we can use this model for PSR B0943 + 10, a quark star candidate, with radius R = 2.6 km and mass M = 0.02 Mʘ. According to our model it turns out that the density on the surface is ρb = 5.3881x1017 kg/m3 and the central density, ρc = 1.0072ρb, is slightly large than the surface density and larger than the nuclear density |
