Comment to ''On Anisotropic Dark Energy Stars''
Francisco S. N. Lobo
Abstrak
The authors of the paper ''On Anisotropic Dark Energy Stars'', arXiv:0803.2508 [gr-qc], consider the equations of state $p_r=ωρ$ and $p_t=ωρ$, ignoring the fact that this implies an isotropic pressure, which places strict restrictions on the values of $ω$. The authors then argue for an anisotropic pressure fluid throughout their work, and apply these equations of state to the energy conditions, consequently obtaining incorrect intervals for the parameter $ω$. This procedure invalidates their criticisms on the following paper: Class.Quant.Grav. 23, 1525 (2006).
