Oxygen enrichment in carbon-rich planetary nebulae
, 2015 We study the relation between the chemical composition and the type of dust present in a group of 20 Galactic planetary nebulae (PNe) that have high quality optical and infrared spectra.

, 2000 "A self-consistent scenario to explain the morphology of planetary nebulae ispresented. This scenario is consistent with the Galactic distribution of di?erentnebular types. This work addresses several controversial features that appear inplanetary nebulae, which are easily solved by the inclusion of MHD e?ects.

PNE 2014-2024: Uma análise da Meta 6 para a construção do novo PNE
Estudos em Avaliação EducacionalO artigo analisou os resultados da Meta 6 do Plano Nacional de Educação, para refletir e propor formas de aperfeiçoar seus indicadores. Políticas de educação em tempo integral foram discutidas, considerando o enfoque das epistemologias da política educacional com perspectiva pluralista, posicionamento crítico-analítico e aspecto crítico-normativo.

Molecular Envelopes of Young and Proto PNE [PDF]
Symposium - International Astronomical Union, 1997 I review recent results of mm-wave interferometric observations of molecular envelopes of young and proto planetary nebulae. Spatial resolutions of mm-wave interferometers now reach from one to a few arcseconds; together with line observations reveale very small structures in molecular envelopes of planetary nebulae.

Distinguishing between symbiotic stars and planetary nebulae
, 2017 Number of known symbiotic stars (SySt) is still significantly lower than their predicted population. One of the main problems in finding complete population of SySt is the fact that their spectrum can be confused with other objects, such as planetary ...

On the Origin of Morphological Structures of Planetary Nebulae
Galaxies, 2018 We suggest that most of the mass in planetary nebulae (PNe) resides in the equatorial region and the spherical envelope and the optically bright lobes of PNe are in fact low-density cavities cleared out by fast outflows and photoionized by UV photons ...

, 2015 Recently, a suspicion arose that the free electrons in planetary nebulae (PNe) and HII regions might have non-thermal energy distributions. In this scenario, a kappa index is introduced to characterize the electron energy distributions, with smaller ...
