... This loss depends on several parameters, in particular on the position where the photon was detected, its energy, the temperature of the CCD, and the saturation of traps by charges preceding along the readout direction. ... For deriving the CTI, each CCD column was split into macro pixels, which were determined by adaptive binning to contain a sufficient number of first singles around the line feature. ...

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. ...

spaceweb@oulu.fi - last update: 11 May 1998, 0900 UT . Matter in the known universe can be classified in terms of four states: solid, liquid, gaseous, and plasma . The basic distinction between solids, liquids and gases lies in the difference between the strength of the bonds that hold their constituent particles together. ... On the other hand, the transition from a gas to an ionized gas, i.e., plasma , is not a phase transition, since it occurs gradually with increasing temperature. ...
