The imprint of arms and bars on rotation curves: in-plane and off-plane
Luis A. Martinez-Medina, Barbara Pichardo, Antonio Peimbert
Within Rotation Curves (RC) is encoded the kinematical state of the stellar disc as well as information about the dynamical mechanisms driving the secular evolution of galaxies. To…
The Contribution of Dwarf Planets to the Origin of Jupiter Family Comets
Marco A. Muñoz-Gutiérrez, Antonio Peimbert, Bárbara Pichardo +2
We explore the long-term evolution of a bias-free orbital representation of the cometary nuclei (with diameters above 2 km) of the Kuiper belt, using the so-called L7 synthetic mod…
First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects
Samuel Navarro-Meza, Michael Mommert, David Trilling +6
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic t…
Dynamics of thick, open spirals in Perlas potentials
L. Chaves-Velasquez, P. A. Patsis, I. Puerari +2
The PERLAS potential has been successfully used in many studies related with the dynamics of the spiral arms \textit{on} the equatorial plane of normal (non-barred) spiral galaxies…
From ridges in the velocity distribution to wiggles in the rotation curve
Luis A. Martinez-Medina, Barbara Pichardo, Antonio Peimbert +1
Recently, the Gaia data release 2 (DR2) showed us the richness in the kinematics of the Milky Way disk. Of particular interest is the presence of ridges covering the stellar veloci…
The Contribution of Dwarf Planets to the Origin of Low Inclination Comets by the Replenishment of Mean Motion Resonances in Debris Disks
Marco A. Muñoz-Gutiérrez, Antonio Peimbert, Bárbara Pichardo
In this work we explore a new dynamical path for the delivery of low-inclination comets. In a configuration formed by an interior giant planet and an exterior massive debris disk,…
