چکیده
We study neutron star configurations in a simple shift-symmetric subfamily of degenerate higher-order scalar-tensor (DHOST) theories, whose deviations from General Relativity (GR) are characterized by single parameter. compute the radial profiles stars these theories modified gravity, using several realistic equations state for matter. find with masses and radii significantly larger than their GR counterparts. then consider slowly-rotating solutions determine relation between dimensionless moment inertia compactness, that has property to be almost insensitive equation state.

Hamiltonian analysis of higher derivative scalar-tensor theories
We perform a Hamiltonian analysis of a large class of scalar-tensor Lagrangians which depend quadratically on the second derivatives of a scalar field. By resorting to a convenient choice of dynamical variables, we show that the Hamiltonian can be written in a very simple form, where the Hamiltonian and the momentum constraints are easily identified. In the case of degenerate Lagrangians, which...
متن کاملScintillation in scalar-tensor theories of gravity
We study the scintillation produced by time-varying gravitational fields within scalar-tensor theories of gravity. The problem is treated in the geometrical optics approximation for a very distant light source emitting quasi plane monochromatic electromagnetic waves. We obtain a general formula giving the time dependence of the photon flux received by a freely falling observer. In the weak-fiel...
متن کاملAccreting neutron stars, black holes, and degenerate dwarf stars.
During the past 8 years, extended temporal and broadband spectroscopic studies carried out by x-ray astronomical satellites have led to the identification of specific compact x-ray sources as accreting neutron stars, black holes, and degenerate dwarf stars in close binary systems. Such sources provide a unique opportunity to study matter under extreme conditions not accessible in the terrestria...
متن کاملCold Black Holes in Scalar-tensor Theories
We study the possible existence of black holes in scalar-tensor theories of gravity in four dimensions. Their existence is verified for anomalous versions of these theories, with a negative kinetic term in the Lagrangian. The Hawking temperature TH of these holes is zero, while the horizon area is (in most cases) infinite. It is shown that an infinite value of TH can occur only at a curvature s...
متن کاملMathematical Modeling of Boson-Fermion Stars in the Generalized Scalar-Tensor Theories of Gravity
A model of static boson-fermion star with spherical symmetry based on scalar-tensor theory of gravity with massive scalar field is investigated numerically. The Continuous Analogue of Newton Method (CANM) for solving the two-parametric nonlinear spectral problem governing the star is used. Since the radius of star is a priori unknown quantity the corresponding boundary value problem is treated ...
