Velocity segregation in a clump-like outflow with a non-top hat velocity cross-section
A. Castellanos-Ramírez, A. C. Raga, J. Cantó +2
High velocity clumps joined to the outflow source by emission with a "Hubble law" ramp of linearly increasing radial velocity vs. distance are observed in some planetary nebulae an…
Twenty years of observations of PM 1-188: Its chemical abundances and extraordinary kinematics
Miriam Peña, Liliana Hernández-Martínez, Francisco Ruiz-Escobedo
The analysis of 20 years of spectrophotometric data of the double shell planetary nebula PM\,1-188 is presented, aiming to determine the time evolution of the emission lines and th…
Chemistry in the dIrr galaxy Leo A
Francisco Ruiz-Escobedo, Miriam Peña, Liliana Hernández-Martínez +1
We present chemical abundance determinations of two H II regions in the dIrr galaxy Leo A, from GTC OSIRIS long-slit spectra. Both H II regions are of low excitation and seem to be…
The metallic winds in dwarf galaxies
F. Robles-Valdez, A. Rodríguez-González, L. Hernández-Martínez +1
We present results from models of galactic winds driven by energy injected from nuclear (at the galactic center) and non-nuclear starbursts. The total energy of the starburst is pr…
A two-mode planetary nebula luminosity function
A. Rodríguez-González, L. Hernández-Martínez, A. Esquivel +4
We propose a new Planetary Nebula Luminosity Function (PNLF) that includes two populations in the distribution. Our PNLF is a direct extension of the canonical function proposed by…
Kinematic study of planetary nebulae in NGC 6822
S. N. Flores-Durán, M. Peña, L. Hernández-Martínez +2
By measuring precise radial velocities of planetary nebulae (which belong to the intermediate age population), H II regions, and A-type supergiant stars (which are members of the y…
