Let I=[0,d), where d is finite or infinite. Let W"@rx=x^@rexp-Qx, where @r-12 and Q is continuous and increasing on I, with limit ~ at d. We study the orthonormal polynomials associated with the weight W"@r^2, obtaining bounds on the orthonormal polynomials, zeros, and Christoffel functions. In addition, we obtain restricted range inequalities.
