14 November 2016 – Are All Stars Created Equal? New findings by international team led by DIAS Astronomer

An international scientific team led by Dr. Alessio Caratti o Garatti from the Astronomy & Astrophysics Section of the School of Cosmic Physics here at DIAS, for the first time observed and analyzed an outburst from a high-mass young stellar object that was caused by material accreting onto the star.
