For $\\Lambda\\ne 0$, we obtain new exact solutions to the Einstein equations and show that they are unique, within that class. For $\\Lambda=0$, we recover the Senovilla-Vera metric and show that it can be locally matched to an Einstein-Rosen type of exterior. Finally, we explore some consequences of the matching, such as trapped surface formation and gravitational radiation in the exterior.","authors_text":"Filipe C. Mena, Irene Brito, M. F.
