VLT Spectroscopic Analysis of HH 202. Implications on dust destruction and thermal inhomogeneities
José N. Espíritu, Antonio Peimbert, Gloria Delgado-Inglada +1
We present a long-slit spectroscopic analysis of Herbig-Haro 202 and the surrounding gas of the Orion Nebula using data from the Very Large Telescope. Given the characteristics of…
On the Survival of High-Altitude Open Clusters within the Milky Way Galaxy Tides
L. A. Martinez-Medina, B. Pichardo, A. Peimbert +1
It is a common assumption that high-altitude open clusters live longer compared with clusters moving close to the Galactic plane. This is because at high altitudes, open clusters a…
The primordial helium abundance and the number of neutrino families
Antonio Peimbert, Manuel Peimbert, Valentina Luridiana
Based on observations of HII regions and the new computations of the recombination coefficients of the He I lines by Porter et al. (2013) we obtain a primordial helium abundance by…
Revealing the spiral arms through radial migration and the shape of the Metallicity Distribution Function
L. A. Martinez-Medina, B. Pichardo, E. Moreno +1
Recent observations show that the Milky Way's metallicity distribution function (MDF) changes its shape as a function of radius. This new evidence of radial migration within the st…
On the Origin of High-Altitude Open Clusters in the Milky Way
L. A. Martinez-Medina, B. Pichardo, E. Moreno +2
We present a dynamical study of the effect of the bar and spiral arms on the simulated orbits of open clusters in the Galaxy. Specifically, this work is devoted to the puzzling pre…
