... 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. ...

... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...
