Van Flandern-Yang hypothesis
Encyclopedia
The van Flandern-Yang hypothesis is the theory attempting to explain the
unusual anomalies of about 7 m/s2 observed
in the
Solar eclipse of March 9, 1997. This hypothesis conjectures that the gravity anomalies are due to a travelling density spot in the upper atmosphere
caused by the cooling during the solar
eclipse. This requires the cooled region should travel at a speed of about 500 to 1000 m/s.
Theoretically, an increase in density of 0.1% could explain the observed anomalies,
but these effects have no direct evidence in observations. In addition, the pressure
variations used for such calculations are extreme values, and in reality such pressure
changes were not observed yet
A detailed review of this hypothesis was summarized in the unpublished article by
C. P. Duif.

An atmosphere is a layer of gases that may surround a material body of sufficient mass, and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low...
