Abstract

The modified gravity (MOG) theory is applied to the gravitational wave binary merger GW190814 to demonstrate that the modified Tolman-Oppenheimer-Volkoff equation for a neutron star can produce a mass M=2.6 -2.7 M_\odot, allowing for the binary secondary component to be identified as a heavy neutron star in the hypothesized mass gap 2.5 - 5 M_\odot.
