ALMA Observations of the Extraordinary Carina Pillars: HH 901/902
Geovanni Cortes-Rangel, Luis A. Zapata, Jesus A. Toala +4
We present Atacama Large Millimeter/Submillimeter Array (ALMA) 1.3 mm continuum and CO(21), ND(32), CS(54), and CO(21) line sensitive and…
Neutron-capture element abundances in the planetary nebula NGC 5315 from deep optical and near-infrared spectrophotometry
S. Madonna, J. García-Rojas, N. C. Sterling +5
We analyze the chemical composition of the planetary nebula (PN) NGC 5315, through high-resolution (R = 40000) optical spectroscopy with UVES at the Very Large Telescope, and mediu…
The chemical composition of Galactic ring nebulae around massive stars
C. Esteban, A. Mesa-Delgado, C. Morisset +1
We present deep spectra of ring nebulae associated with Wolf-Rayet (WR) and O-type stars: NGC 6888, G2.4+1.4, RCW 58, S 308, NGC 7635 and RCW 52. The data have been taken with the…
Ring Nebulae: Tracers of the CNO Nucleosynthesis
A. Mesa-Delgado, C. Esteban, J. García-Rojas
Preliminary results are presented from spectroscopic data in the optical range of the Galactic ring nebulae NGC 6888, G2:4+1:4, RCW 58 and Sh2-308. Deep observations with long expo…
A Consistent Spectral Model of WR 136 and its Associated Bubble NGC 6888
J. Reyes-Pérez, C. Morisset, M. Peña +1
We analyse whether a stellar atmosphere model computed with the code CMFGEN provides an optimal description of the stellar observations of WR 136 and simultaneously reproduces the…
