Refraction, Gravitational Lensing, Negative Parallaxes and Dark Matter

Authors: Saverio Donnini

Here, we speculate on the causes of negative parallaxes of stars. We first summarize the concepts of refractional and gravitational lens, and we highlight the similarities between the two. We then analyze the relation between negative parallaxes and temperature of stars, and negative parallaxes and distance of stars. We observe that warmer and more distant stars show a larger number of negative parallaxes, with respect to colder and closer stars, respectively. Is refraction of light through a medium of astronomical bodies the cause of the observed stars parallaxes ? And moreover, could these astronomical bodies explain dark matter?
