A Spectral Atlas of HII Galaxies in the Near-Infrared
Lucimara P. Martins, Alberto Rodríguez-Ardila, Suzi Diniz +2
Recent models show that TP-AGB stars should dominate the NIR spectra of populations 0.3 to 2 Gyr old, leaving unique signatures that can be used to detect young/intermediate stella…
Molecular chemistry and the missing mass problem in PNe
Rafael K. Kimura, Ruth Gruenwald, Isabel Aleman
Detections of molecular lines, mainly from H2$ and CO, reveal molecular material in planetary nebulae. Observations of a variety of molecules suggest that the molecular composition…
3-D Photoionization Structure and Distances of Planetary Nebulae IV. NGC 40
Hektor Monteiro, Diego Falceta-Gonçalves
Continuing our series of papers on the 3-D structure and accurate distances of Planetary Nebulae (PNe), we present here the results obtained for the planetary nebula NGC\,40. Using…
Modelling the Warm H2 Infrared Emission of the Helix Nebula Cometary Knots
Isabel Aleman, Albert A. Zijlstra, Mikako Matsuura +2
Molecular hydrogen emission is commonly observed in planetary nebulae. Images taken in infrared H2 emission lines show that at least part of the molecular emission is produced insi…
H2 infrared line emission from the ionized region of planetary nebulae
Isabel Aleman, Ruth Gruenwald
The analysis and interpretation of the H2 line emission from planetary nebulae have been done in the literature assuming that the molecule survives only in regions where the hydrog…
Modelling H2 Infrared Emission of the Helix Nebula Cometary Knots
Isabel Aleman, Albert A. Zijlstra, Mikako Matsuura +2
In the present work, we use a photoionisation code to study the H2 emission of the Helix nebula (NGC 7293) cometary knots, particularly that produced in the interface H+/H0 of the…
