Resumen:
We obtain the (super) gravity solution in arbitrary space-time dimension less
than ten, that gives a low energy description of a fundamental string embedded
in a non critical vacuum, product of $d$-dimensional Minkowski space-time and a
cigar-like geometry with scale $r_0$. This solution, one of the few known
examples of objects doubly localized, both at the origin of the transverse
space as well as at the tip of the cigar, is determined by its charge $Q$ under
the Kalb-Ramond gauge field $B$, and presumably preserves, for even $d$,
$2^\frac{d}{2}$ supercharges. Moreover, we show that the solution is reliable
at least in a region far away from both origins, as it is the case with the
well known branes of critical string theory.
