Flow of material observed for the first time around a young eruptive star

Every year, about two Earth masses of material flows to the disk of the young star V346 Nor from its surroundings, to end up on the star causing brightening. The hard-to-see phenomenon was captured by a Hungarian-led research group using ALMA, the largest astronomical telescope on Earth. The observation helps in the understanding of a key phenomenon: how circumstellar disks evolve and ultimately form planets.
