An international team of astronomers, including Dr Simon Vaughan from the University of Leicester’s Department of Physics and Astronomy, has discovered a previously unknown link between the way young stars grow and the way black holes and other exotic space objects feed from their surroundings. The study, ‘Accretion-induced variability links young stellar objects, white dwarfs, …



The golden anniversary of black-hole singularity

The golden anniversary of black-hole singularity

When a star collapses forming a black hole, a space-time singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that singularity with so-called ”trapped surfaces” that shrink over time. That hypothesis -one of the results of the general theory of relativity- is …
