The excitation mechanism of H2 in bipolar planetary nebulae
R. A. Marquez-Lugo, Martin A. Guerrero, Gerardo Ramos-Larios +1
We present near-IR K-band intermediate-dispersion spatially-resolved spectroscopic observations of a limited sample of bipolar planetary nebulae (PNe). The spectra have been used t…
A search for water maser emission toward obscured post-AGB star and planetary nebula candidates
J. F. Gomez, J. R. Rizzo, O. Suarez +5
Water maser emission at 22 GHz is a useful probe to study the transition between the nearly spherical mass-loss in the AGB to a collimated one in the post-AGB phase. In their turn,…
Time-variable non-thermal emission in the planetary nebula IRAS 15103-5754
Olga Suarez, Jose F. Gomez, Philippe Bendjoya +6
The beginning of photoionization marks the transition between the post-Asymptotic Giant Branch (post-AGB) and planetary nebula (PN) phases of stars with masses < 8 M_sun. This crit…
WISE morphological study of Wolf-Rayet nebulae
J. A. Toalá, M. A. Guerrero, G. Ramos-Larios +1
We present a morphological study of nebulae around Wolf-Rayet (WR) stars using archival narrow-band optical and Wide-field Infrared Survey Explorer (WISE) infrared images. The comp…
