An article published in the journal “Nature” describes a research on the influence of supermassive black holes on star formation in large galaxies. A team of researchers analyzed that feedback mechanism concluding that there’s a correlation between the mass of those black holes and the effect of inhibiting the formation of new stars.
An article published in the journal “Proceedings of the National Academy of Sciences” describes a research that tries to provide an estimate of the possibilities for the 7 planets of the ultra-cool dwarf star TRAPPIST-1 to maintain an atmosphere. A team of researchers created simulations that took into account the characteristics of TRAPPIST-1’s stellar wind and the possible speed at which the planets’ atmosphere would be torn away from them. The conclusion is that the two outermost planets could maintain an atmosphere for billions of years.
