Bayesian posterior classification of planetary nebulae according to the Peimbert types
C. Quireza, H. J. Rocha-Pinto, W. J. Maciel
In this paper we present a re-analysis of the criteria used to characterize the Peimbert classes I, IIa, IIb, III and IV, through a statistical study of a large sample of planetary…
The Electron Temperature Gradient in the Galactic Disk
C. Quireza, R. T. Rood, T. M. Bania +2
We derive the electron temperature gradient in the Galactic disk using a sample of HII regions that spans Galactocentric distances 0--17 kpc. The electron temperature was calculate…
Radio Recombination Lines in Galactic HII Regions
Cintia Quireza, Robert T. Rood, Dana S. Balser +1
We report radio recombination line (RRL) and continuum observations of a sample of 106 Galactic HII regions made with the NRAO 140 Foot radio telescope in Green Bank, WV. We believ…
