heal.abstract	We study q-stars in Brans-Dicke gravitational theory. We find that when the Brans-Dicke constant, omega(BD), tends to infinity, the results of general relativity are reproduced. For other values of omega(BD), the particle number, mass and radius of the star and the absolute value of the matter field are a few percent larger than in the case of general relativity. We also investigate the general scalar-tensor gravitational theory and find that the star parameters are a few percent larger than in the case of general relativity. (c) 2005 Elsevier B.V.
