1203.3755 (Claudio Simeone)

Addendum to "Thin-shell wormholes supported by ordinary matter in
Einstein-Gauss-Bonnet gravity"
   [PDF]

Claudio Simeone
Thin-shell wormholes are constructed starting from the exotic branch of Wiltshire spherically symmetric solution of Einstein-Gauss-Bonnet gravity. The energy-momentum tensor of the shell is studied, and it is shown that configurations supported by matter satisfying the energy conditions exist for certain values of the parameters. Differing from the previous result associated to the normal branch of Wiltshire solution, this is achieved for small positive values of the Gauss-Bonnet parameter and for vanishing charge.
