Plugstars, Alternative to Black Holes
Résumé
We focus on the only directly usable data from images of hypermassive objects at the center of the M 87 and Milky Way galaxies, namely the ratios of maximum to minimum temperatures, in both cases very close to 3. To explain that their center remain emissive, it has been suggested that there is some hot gaz, belonging to an accretion disk, located at the foreground. But as this hypothetical accretion disk does not extend beyond the images, their identification as giant black holes is questionable. After examining what led to the emergence of the black hole theory, and evoking the alternative of gravastars, we show that the plugstars model, where the darkening of the central part is then attributed to a subcritical situation, is the only one that fits perfectly available observational data.
