The model of dwarf spheroidal galaxies consists of ten thousand stars, and we model their internal gravity as a Plummer potential. In the case of EFE, we treat the host galaxy as fixed point mass on the positive x-axis, and consider the fully three dimensional MOND equations. The bulk dispersion and dispersion profile are then calculated statistically. For each galaxy, we obtain results for Newtonian, isolated MOND, and external field effect MOND. By changing the mass-to-light ratio of the spheroidal galaxies we obtained results for bulk dispersions and dispersion profiles that agree fairly well with observational data. 2020-07-28 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1595892257810885 http://rave.ohiolink.edu/etdc/view?acc_num=miami1595892257810885 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
