Note that the APOD image makes it look like the two Gamma-ray sources are in near proximity to one another. [Added 21 Sep 2012.]

Coordinates for Geminga and Crab Pulsars

                    Right Ascension         Declination
Geminga SN 437       06hr 33min 54sec       17deg 46min 12.9sec
Crab PSR0531 +21    05hr 34min 32sec       22deg 00min 52.0sec

See A Ritzian Interpretation of Variable Stars for background material on the astrophysical hypothesis being modeled on this web page.

The light curve of the Geminga gamma-ray pulsar is double-peaked (with an interior bridge). It's repetition period is about 1/4 second (0.237 sec) and at least one neutron star is thought to be involved in the production of the pulse train.

Here is the NASA/GSFC EGRET lightcurve of Geminga.

Below are computer modeling printouts for a Ritzian relativity process which may be responsible for Geminga's unique light curve. The printouts show light and apparent radial velocity curves for a single visible component of a close binary star system with an extinction distance of 1.5 times the Ritz-de Sitter overtaking distance (Lo). (An extinction distance on the order of 2.5 Lo will be needed to more properly approximate the Geminga light curve.)

The orbit being modeled has an eccentricity of 0.2 and print-outs are made for perihelion angles decremented in 90 degree steps. (Orbit eccentricities are exaggerated in the figures.)






The light curves of Geminga are most similar to the last figure in this series.
