             abstract = "The objective of this paper is to study the problem of 
                         gravitational capture in the regularized restricted three-body 
                         problem. A gravitational capture occurs when a massless particle 
                         changes its two-body energy around one celestial body from 
                         positive to negative without the use of non-gravitational forces. 
                         We studied the importance of several of the parameters involved 
                         for a capture in the Earth-Moon system, including the time 
                         required for the capture and the effects of the periapse distance. 
                         Then, we generalize those results for other binary systems, like 
                         the Sun-Earth, Sun-Mars and Sun-Jupiter systems. Next, we cover 
                         the whole interval of the mass parameter (the mass ratio of the 
                         two primaries) and we study the gravitational capture in the 
                         interval 0.0 < < 0.5. The elliptical restricted problem is also 
                         considered as an option for the model.",
