Of course, they have nothing to do with planets but rather represent late stages in the evolution of low mass stars in which a double shell source (Hydrogen and Helium Burning) around a non-fusing Carbon core is driving the outer layes of the star away, thus revealing a hotter star (the central star of the Planetary nebula). ...

... GSAOI Home . ... Science . ... Despite vast increase in our understanding of the evolutionary nature of planetary nebulae (PNe) during the last three decades, a central question remains: where is the missing mass? Theoretical evolutionary tracks predict that all stars with masses in the range 1.4-8 M Sun should become PNe. ... Clearly, much of the mass of the planetary nebula shell must remain un-ionized, and much of it may be in molecular form. ... The Magellanic Cloud PNe are ideal for this. ...
