Picosecond-level corrections to the Shapiro time delay in a Schwarzschild spacetime
Oscar del Barco
We present an exact analytical equation for the Shapiro time delay (STD) due to a spherical non-rotating body. As a result, accurate values of the STD in comparison with first and…

An accurate equation for the gravitational bending of light by a static massive object
Oscar del Barco
An exact analytical expression for the bending angle of light due to a non-rotating massive object, considering the actual distances from source and observer to the gravitational m…
