How Stellar Death Can Lead To Twin Celestial Jets
Rochester NY (SPX) Feb 14, 2014
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 So ... read more
