Louis George Henyey (February 3, 1910 – February 18, 1970) was an American astronomer.. His parents, Albert and Mary Henyey, were immigrants from Hungary. Louis George Henyey married Elizabeth Rose Belak, born in Budapest, on April 28, 1934; they had three children: Thomas Louis, Francis Stephen, and Elizabeth Maryrose.
Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of photon movement between sites of photon-matter interaction and the angles of deflection in a photon's trajectory when a scattering event occurs.

Jesse Leonard Greenstein (October 15, 1909 – October 21, 2002) was an American astronomer. [1] His parents were Maurice G. and Leah Feingold. He earned a Ph.D, with thesis advisor Donald H. Menzel , from Harvard University in 1937, having started there at age 16. [ 2 ]
The Henyey track is a path taken by pre-main-sequence stars with masses greater than 0.5 solar masses in the Hertzsprung–Russell diagram after the end of the Hayashi track. The astronomer Louis G. Henyey and his colleagues in the 1950s showed that the pre-main-sequence star can remain in radiative equilibrium throughout some period of its ...
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering.
The redshift of Sirius B was finally measured by Greenstein et al. in 1971, obtaining the value for the gravitational redshift of 89 ± 16 km/s, with more accurate measurements by the Hubble Space Telescope showing 80.4 ± 4.8 km/s. [38]
Another more recent phenomenon discovered via this approach is the Bose–Einstein correlation between particles and antiparticles [citation needed]. The wave function of two identical particles is symmetric or antisymmetric with respect to the permutation of the two particles, depending whether one considers identical bosons or identical fermions.
