We study the number of limit cycles, which bifurcate from a two-saddle loop of a planar quadratic Hamiltonian system, under an arbitrary quadratic deformation. It is shown that there are "alien" limit cycles, which do not correspond to zero sets of Abelian integrals. Reference: http://arxiv.org/abs/1306.2340
