Photodissociation of organic molecules in star-forming regions, III. Methanol
S. Pilling, R. Neves, A. C. F. Santos +1
The presence of methyl alcohol or methanol (CHOH) in several astrophysical environments has been characterized by its high abundance that depends on both the production rate an…
Production of H via photodissociation of organic molecules in interstellar clouds
S. Pilling, D. P. P. Andrade, R. Neves +3
We present experimental results obtained from photoionization and photodissociation processes of abundant interstellar CH-X type organic molecules like methanol (CHOH), met…
On the hydrogen neutral outflowing disks of B[e] supergiants
Michaela Kraus, Marcelo Borges Fernandes, Francisco X. de Araujo
(abridged) B[e] supergiants are known to possess geometrically thick dusty disks. Disk-forming wind models have, however, been found to be insufficient in reproducing the observed…
HII Galaxies with 3D Spectroscopy
C. Kehrig, J. M. Vilchez, S. F. Sanchez +3
We present our ongoing work on integral field spectroscopy of three prototypical HII galaxies: IIZw70, IIZw71 and IZw18. The data are mainly used to study the ionized gas and stell…
On the structure of giant HII regions and HII galaxies
G. Tenorio-Tagle, C. Munoz-Tunon, E. Perez +2
We review the structural properties of giant extragalactic HII regions and HII galaxies based on two dimensional hydrodynamic calculations, and propose an evolutionary sequence tha…
Detailed Far-UV to Optical Analysis of Four [WR] Stars
W. L. F. Marcolino, D. J. Hillier, F. X. de Araujo +1
We present far-UV to optical analyses of four hydrogen deficient central stars of planetary nebulae: BD+303639, NGC 40, NGC 5315 and NGC 6905. Using the radiative transfer code CMF…
