abstract: 'The core accretion theory of planetary formation does not predict that super-Jupiters will form beyond the snow line of a low mass stars. We present a discovery of $3.9\pm1.2~M_{\rm Jup}$ mass planet orbiting the $0.59\pm0.17~M_{\odot}$ star using the gravitational microlensing method. During the event, the projected separation of the planet and the star is $3.9\pm1.0~{\rm AU}$ i.e., the planet is significantly further from the host star than the snow line. This is a fourth such planet discovered using the microlensing technique and challenges the core accretion theory.'

Introduction
============

There are two main theories of planetary formation: core accretion and gravitational instability. The first one does not predict planets to be formed much beyond the snow line (the ring in protoplanetary disks where the temperature is below the sublimation temperature of ice). One of the tests for these theories is the observational census of the super-Jupiter mass planets around low-mass stars, i.e., M
