The influence of planetary nebula gas density fluctuations to its emission line spectra
The set of spheric-simmetrical photoionization models of planetary nebula luminescence for different radial gas density distributions for central stars temperatures T = 50000 K and T = 100000 K was created. Gas density fluctuations were chosen randomly. Every range of models was assumed to have basi...

| description | The set of spheric-simmetrical photoionization models of planetary nebula luminescence for different radial gas density distributions for central stars temperatures T = 50000 K and T = 100000 K was created. Gas density fluctuations were chosen randomly. Every range of models was assumed to have basic homogeneous gas density( n(H) = 500 cm^-3 and n(H) = 1000 cm^-3) and density fluctuations more 2, 5, 10, 15 and 20 times. The line emission spectrum of each planetary nebula model was calculated. We have chosen a set of 10 lines for which the influence of density fluctuations may be neglected, so these lines may be used for more accurate planetary nebula chemical abundance determination. |
