NGC 6791 is one of the most studied open clusters, it is massive (), located at the solar circle, old (Gyr) and yet the most metal-rich cluster (${\rm [F…
Giant Planets Can Act As Stabilizing Agents on Debris Disks
Marco A. Muñoz-Gutiérrez, Bárbara Pichardo, Antonio Peimbert
We have explored the evolution of a cold debris disk under the gravitational influence of dwarf planet sized objects (DPs), both in the presence and absence of an interior giant pl…
Nebular spectroscopy: A guide on H II regions and planetary nebulae
Manuel Peimbert, Antonio Peimbert, Gloria Delgado-Inglada
We present a tutorial on the determination of the physical conditions and chemical abundances in gaseous nebulae. We also include a brief review of recent results on the study of g…
Dynamics and Morphology of the Milky Way Spiral Arms from the Metallicity Distribution and Radial Mixing
L. A. Martinez-Medina, B. Pichardo, A. Peimbert +1
Albeit radial migration must be a ubiquitous process in disc galaxies, its significance in the evolution of stellar discs is not always reflected through global trends. However, th…
