Abstract

Tidal deformation of a gravitational body can occur because of many reasons. One of them is due to the gravitational potential from other bodies. The tidal deformations within Newtonian, N-dimension Newtonian and general relativity have been studied in Ref. [1]. In this work, we study the impact of Beyond Horndeski modified gravity theory on tidal deformation within the Newtonian framework since we are eager to know how the theory affects that property. In our calculations, we use the white dwarf star as the representation of the astrophysical object and assume that the gravity object to be static and non-relativistic. In this research we found that the deformability of white dwarf star is modified and inversely proportional to the value of Beyond Horndeski parameter.
