Abstract
The main aim of this work is to investigate the effect of charge transfer reaction upon gaseous nebula structure, temperature and recombination coefficients of nitrogen and oxygen. We have been used CLOUDY 90 to determine the ionization structure of nitrogen and oxygen. We have used the abundance of heavy elements relative to hydrogen He = -1.07, C = -3.44, N = -4.07, O = -3.31 and Ne = -3.91. Ionization structure of hydrogen, helium, oxygen and nitrogen, electron temperature and the recombination coefficient are compared with the effective temperatures of 75000 K and 100000 K with the luminosity intensity of 10 38 erg s -1 . The result revealed that the ionization structures of elements are highly dependent on the transfer of charge and effective temperatures. In addition, we also tabulate the recombination coefficient of nitrogen and oxygen at different states with temperature of 5000 K, 10000 K, 15000 K and 20000 K. This calculation confirms with the results of previous calculation done by different scholars.
Highlights
In charge reactions, a singly charged ion such as H+ or O+ collides with neutral atom or molecule and captures one of its electrons, thereby becoming a neutral atom
In this work we focus on the impacts of these elements on assessing the model of photoionization and the ionization structure, temperature of electrons by evaluating the recombination coefficients of nitrogen and oxygen
Using the CLOUDY photoionization code, we were able to calculate the ionization structure of nitrogen and oxygen on charge transfer reaction has substantial affected by blackbody temperature
Summary
A singly charged ion such as H+ or O+ collides with neutral atom or molecule and captures one of its electrons, thereby becoming a neutral atom. A small of energy is transferred to the electron donor, so the newly formed neutral retains most of the original energy of the ion. Since it does not longer carry a charge, the neutral atom is not affected by electric and magnetic fields and travels along a straight line of sight path from the point where it was formed. Different result in the last few decades shows that heavy elements have impact on photoionization model of gaseous nebulae. In this work we focus on the impacts of these elements on assessing the model of photoionization and the ionization structure, temperature of electrons by evaluating the recombination coefficients of nitrogen and oxygen. We will investigate the intensity ratio of the spectrum [O I], [O II], [O III] and [N II] in the presence and absence of charge exchange between hydrogen ions and oxygen or nitrogen atoms
