surfQuake: A new Python toolbox for the workflow process of seismic sources
Roberto Cabieces, Thiago C. Junqueira, Katrina Harris +2
surfQuake is a new software designed to streamline the estimation of seismic source parameters. Its comprehensive set of toolboxes automate the determination of seismic arrival tim…
How does the stellar disk of the Milky Way get its gas?
Sebastian E. Nuza, Cristina Chiappini, Cecilia Scannapieco +3
In chemodynamical evolution models it is usually assumed that the Milky Way galaxy forms from the inside-out implying that gas inflows onto the disk decrease with galactocentric di…
Gas accretion in Milky Way-like galaxies: temporal and radial dependencies
Sebastian E. Nuza, Cecilia Scannapieco, Cristina Chiappini +3
One of the fundamental assumptions of chemical evolution models (CEMs) of the Milky Way (MW) and other spirals is that higher gas accretion rates are expected in the past, and in t…
A Galactic Ring of Minimum Stellar Density Near the Solar Orbit Radius
Douglas A. Barros, Jacques R. D. Lépine, Thiago C. Junqueira
We analyse the secular effects of a long-lived Galactic spiral structure on the stellar orbits with mean radii close to the corotation resonance. By test-particle simulations and d…
Bimodal chemical evolution of the Galactic disk and the Barium abundance of Cepheids
Jacques R. D. Lepine, Sergei Andrievky, Douglas A. Barros +2
In order to understand the Barium abundance distribution in the Galactic disk based on Cepheids, one must first be aware of important effects of the corotation resonance, situated…
A new model for gravitational potential perturbations in disks of spiral galaxies. An application to our Galaxy
T. C. Junqueira, J. R. D. Lépine, C. A. S. Braga +1
We propose a new, more realistic, description of the perturbed gravitational potential of spiral galaxies, with spiral arms having Gaussian-shaped groove profiles. We investigate t…
The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
J. R. D. Lepine, A. Roman-Lopes, Zulema Abraham +2
We present a map of the spiral structure of the Galaxy, as traced by molecular CS emission associated with IRAS sources which are believed to be compact HII regions. The CS line ve…
