Abstract
We study points of moderately low degree on a curve over a number field, which is embedded on a nice toric surface . Recently, Smith and Vogt related the linear equivalence classes of such points to intersections of with curves in the ambient surface. We show that when is sufficiently effective and ample with simple singularities, all but finitely many sufficiently low degree points are obtained via intersections of with curves in the ambient surface . Our methods make use of the toric geometry of the ambient surface to produce curves which interpolate the low degree points on . Furthermore, we generalise a result by Debarre and Klassen to singular plane curves and higher degrees of points.
