Static cylindrical symmetry and conformal flatness
L. Herrera, G. Le Denmat, G. Marcilhacy +1
We present the whole set of equations with regularity and matching conditions required for the description of physically meaningful static cylindrically symmmetric distributions of…
Shear-free radiating collapse and conformal flatness
L. Herrera, G. Le Denmat, N. O. Santos +1
Here we study some general properties of spherical shear-free collapse. Its general solution when imposing conformal flatness is reobtained [1,2] and matched to the outgoing Vaidya…
Generalised equilibrium of cosmological fluids in second-order thermodynamics
Winfried Zimdahl, J'er^ome Gariel, G'erard Le Denmat
Combining the second-order entropy flow vector of the causal Israel-Stewart theory with the conformal Killing-vector property of , where is the four-velocity of th…
Gravitational dust collapse with cosmological constant
M. Cissoko, J. C. Fabris, J. Gariel +2
We study the fate of gravitational collapse in presence of a cosmological constant. The junctions conditions between static and non-static space-times are deduced. Three apparent h…
