Monitoring the Large Proper Motions of Radio Sources in the Orion BN/KL Region
Laura Gomez, Luis F. Rodriguez, Laurent Loinard +4
We present absolute astrometry of four radio sources in the Becklin-Neugebauer/Kleinman-Low (BN/KL) region, derived from archival data (taken in 1991, 1995, and 2000) as well as fr…
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 Frequency Distribution of Semi-major Axis of Wide Binaries. Cosmogony and Dynamical Evolution
A. Poveda, C. Allen, A. Hernandez-Alcantara
The frequency distribution f(a) of semi-major axis of double and multiple systems, as well as their eccentricities and mass ratios, contain valuable fossil information about the pr…
Halo Wide Binaries and Moving Clusters as probes of the Dynamical and Merger History of our Galaxy
Christine Allen, Arcadio Poveda, A. Hernandez-Alcantara
Wide or fragile pairs are sensitive probes of the galactic potential, and they have been used to provide information about the galactic tidal field, the density of GMC and the mass…
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.…
HST Images Do Not Support the Presence of Three High Velocity, Low-Mass Stars in the Core of the Orion Nebula Cluster
C. R. O'Dell, Arcadio Poveda, Christine Allen +1
A recent article has employed the determination from groundbased images of high proper motions in the Orion Nebula Cluster to argue that JW 349, JW 355, and JW 451 are high velocit…
