Six New Galactic Orbits of Globular Clusters in a Milky-Way-Like Galaxy
Christine Allen, Edmundo Moreno, Barbara Pichardo
Absolute proper motions for six new globular clusters have recently been determined. This motivated us to obtain the Galactic orbits of these six clusters both in an axisymmetric G…
The extraordinary LBV/WR system HD 5980
Gloria Koenigsberger, Edmundo Moreno
The LBV/WR system HD 5980 contains a short-period, eccentric binary system with interacting stellar winds. In this paper we summarize results from model calculations of the tidal f…
Tides in asynchronous binary systems
Oswaldo Toledano, Edmundo Moreno, Gloria Koenigsberger +2
Stellar oscillations are excited in non-synchronously rotating stars in binary systems due to the tidal forces. Tangential components of the tides can drive a shear flow which beha…
The orbits of 48 globular clusters in a Milky-Way-Like Barred Galaxy
Christine Allen, Edmundo Moreno, Barbara Pichardo
The effect of a barred potential (such as the one of the Milky Way) on the galactic orbits of forty-eight globular clusters for which absolute proper motions are known is studied.…
A Plausible Galactic Spiral Pattern and its Rotation Speed
M. Martos, X. Hernandez, M. Yanez +2
We report calculations of the stellar and gaseous response to a Milky Way mass distribution model including a spiral pattern with a locus as traced by K-band observations, over imp…
Models for the Gravitational Field of the Galactic Bar. An Application to Stellar Orbits in the Galactic Plane and Orbits of Some Globular Clusters
Barbara Pichardo, Marco Martos, Edmundo Moreno
We built three models for the gravitational field of the Galactic bar. These models are an inhomogeneous ellipsoid, an inhomogeneous prolate spheroid, and a superposition of four i…
