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,…
The HST large programme on Centauri -- III. Absolute proper motion
M. Libralato, A. Bellini, L. R. Bedin +11
In this paper we report a new estimate of the absolute proper motion (PM) of the globular cluster NGC 5139 ( Cen) as part of the HST large program GO-14118+14662. We analyzed a…
