A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported ...
A study by Politecnico di Torino published in the journal Physical Review E demonstrates that a wave in a fluid requires amplified vorticity and not only amplified energy in order to change the nature of the flow
