    "abstract": "We present a model of bi-phasic vesicle in the limit of large surface\ntension. In this regime, the vesicle is completely stretched and well described\nby two spherical caps with a fold which concentrates the membrane stress. The\nconservation laws and geometric constraints restrict the space of possible\nshapes to a pair of solutions labeled by a parameter $\\tau$ given by {\\it line\ntension/pressure}. For a given $\\tau$ value, the two solutions differ by the\nlength of the interface between domains. For a critical value $\\tau\\_c$, the\ntwo vesicle shapes become identical and no solution exists above this critical\nvalue. This model sheds new light on two proposed mechanisms (osmotic shocks\nand molecule absorption) to explain the budding and the fission in recent\nexperiments.",
