Optical spectrum of M 2-24
Listed in IVOA Registry (Virtual Observatory)
We have obtained medium-resolution, deep optical long-slit spectra of the bulge planetary nebula (PN) M 2-24.
Description
The spectrum covers the wavelength range from 3610-7330{AA}. Over two hundred emission lines have been detected.
The spectra show a variety of optical recombination lines (ORLs) from C, N, O and Ne ions. The diagnostic diagram shows significant density and temperature variations across the nebula. Our analysis suggests that the nebula has a dense central emission core.

The nebula was thus studied by dividing it into two regions: 1) an high ionization region characterized by an electron temperature of T_e_=16300K and a density of logN_e_(cm^-3^)=6.3; and 2) a low ionization region represented by T_e_=11400K and logN_e_(cm^-3^)=3.7. A large number of ORLs from C, N, O and Ne ions have been used to determine the abundances of these elements relative to hydrogen. In general, the resultant abundances are found to be higher than the corresponding values deduced from collisionally excited lines (CELs).
This bulge PN is found to have large enhancements in two {alpha}-elements, magnesium and neon.
