Query: White dwarfs in de Rham-Gabadadze-Tolley like massive gravity   The existence of possible massive white dwarfs more than the Chandrasekhar
limit ($1.45M_{\odot }$, in which $M_{\odot }$ is mass of the sun) is a
challenging topic. In this regard and motivated by the important effect of
massive graviton on the structure of white dwarfs we study the white dwarfs in
Vegh's massive gravity which is known as one of theories of de Rham, Gabadadze
and Tolley (dRGT) like massive gravity. First, we consider the modified
Tolman-Oppenheimer-Volkoff equation in this theory of massive gravity and solve
it numerically by using the Chandrasekhar's equation of state. Our results show
that the maximum mass of white dwarfs in massive gravity can be more than the
Chandrasekhar limit ($M>1.45M_{\odot }$ ), and this result imposes some
constraints on parameters of massive gravity. Then, we investigate the effects
of various parameters on other properties of the white dwarfs such as
mass-radius relation, mass-central density relation, Schwarzschild radius,
average density and Kretschmann scalar. Next, we study dynamical stability
condition for super-Chandrasekhar white dwarfs and show that these massive
compact objects enjoy dynamical stability. Finally, in order to have a better
insight, we compare the super-Chandrasekhar white dwarfs with the obtained
massive neutron stars in dRGT like massive theory of gravity.
