Waspie_Dwarf Posted February 13, 2014 #1 Share Posted February 13, 2014 How Stellar Death Can Lead To Twin Celestial Jets Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae — colorful, glowing clouds of dust and gas. In recent decades these nebulae, once thought to be mostly spherical, have been observed to often emit powerful, bipolar jets of gas and dust. But how do spherical stars evolve to produce highly aspherical planetary nebulae?In a theoretical paper published this week in the Monthly Notices of the Royal Astronomical Society, a University of Rochester professor and his undergraduate student conclude that only "strongly interacting" binary stars — or a star and a massive planet — can feasibly give rise to these powerful jets.
