We consider a parabolic 2D Free Boundary Problem,
with jump conditions at the interface. Its planar travelling-wave solutions
are orbitally stable
provided the bifurcation parameter $u_*$
does not exceed a critical value $u_\{*\}^\{c\}$. The latter is
the limit of a decreasing sequence $(u_\{*\}^\{k\})$
of bifurcation points. The paper deals with the study of the 2D
bifurcated branches
from the planar branch, for small k.
Our technique is based on the elimination of the unknown front,
turning the problem into a fully nonlinear one, to which we can
apply the Crandall-Rabinowitz bifurcation theorem for a local study.
We point out that the
fully nonlinear reformulation of the FBP can also serve to develop
efficient numerical schemes in view of global information, such as
techniques based on arc length continuation.

We consider a parabolic 2D Free Boundary Problem,
with jump conditions at the interface. Its planar travelling-wave solutions
are orbitally stable
provided the bifurcation parameter $u_*$
does not exceed a critical value $u_{*}^{c}$. The latter is
the limit of a decreasing sequence $(u_{*}^{k})$
of bifurcation points. The paper deals with the study of the 2D
bifurcated branches
from the planar branch, for small k.
Our technique is based on the elimination of the unknown front,
