We study the integrability of two-dimensional autonomous systems in the plane of the form =-y+Xs(x,y), =x+Ys(x,y), where Xs(x,y) and Ys(x,y) are homogeneous polynomials of degree s with s≥2. First, we give a method for finding polynomial particular solutions and next we characterize a class of integrable systems which have a null divergence factor given by a quadratic polynomial in the variable (x2+y2)s/2-1 with coefficients being functions of tan−1(y/x).
