The transparent Sun is modeled as a spherically symmetric and centrally condensed gravitational lens using recent standard solar model (SSM) data. The Sun's minimum focal length is computed to a refined accuracy of 23.5 ± 0.1 AU, just beyond the orbit of Uranus. The Sun creates a single image of a distant point source visible to observers inside this minimum focal length and to observers sufficiently removed from the line connecting the source through the Sun's center. Regions of space are…

The Uniform Transparent Gravitational Lens
An elementary discussion is given of the gravitational deflection of light due to radially and cylindrically symmetric masses. The effect of the deflection on apparent luminosity of distant sources
Gravitational Lensing in Astronomy
Although still in its childhood, lensing has established itself as a very useful astrophysical tool with some remarkable successes and is predicted to have an even more luminous future for gravitational lensing.
Focusing of gravitational radiation by interior gravitational fields
SummaryThe deflection of rays of gravitational radiation passing through, the interior of a diffuse, static, spherically symmetric distribution of matter is examined along with the focusing of the
A diffraction limit on the gravitational lens effect
The focussing of gravitational radiation by the interior and exterior gravitational field of a Newtonian gravitational lens is considered. A graphical method for determining the caustic structure of
Visual distortions near a neutron star and black hole
The visual distortion effects visible to an observer traveling around and descending to the surface of an extremely compact star are described. Specifically, trips to a ‘‘normal’’ neutron star, a
Gravitational lensing of gravitational waves from inspiraling binaries by a point mass lens
Gravitational lensing of gravitational waves from inspiraling binaries is discussed in the context of advanced laser-interferometer detectors, taking correct account of the diffraction effect.
A Determination of the Deflection of Light by the Sun's Gravitational Field, from Observations Made at the Total Eclipse of May 29, 1919
1. The purpose of the expeditions was to determine what effect, if any, is produced by a gravitational field on the path of a ray of light traversing it. Apart from possible surprises, there appeared
Gravitational Radiation in the Limit of High Frequency. I. The Linear Approximation and Geometrical Optics
A formalism is developed for obtaining approximate gravitational wave solutions to the vacuum Einstein equations of general relativity in situations where the gravitational fields of interest are
