On the dynamical evolution of the Orion Trapezium
C. Allen, R. Costero, A. Ruelas-Mayorga +1
We discuss recent observational data on the transverse and radial velocities, as well as on the masses of the main components of the Orion Trapezium. Based on the most reliable val…
Kinematics of the Orion Trapezium Based on Diffracto-Astrometry and Historical Data
J. Olivares, L. J. Sánchez, A. Ruelas-Mayorga +3
Using the novel Diffracto-Astrometry technique, we analyze 44 Hubble Space Telescope Wide Field Planetary Camera 2 images of the Orion Trapezium (OT) taken over a span of 12 yr (19…
Flattened velocity dispersion profiles in Globular Clusters: Newtonian tides or modified gravity?
X. Hernandez, M. A. Jimenez, C. Allen
Over the past couple of years, a number of observational studies have confirmed the flattening of the radial velocity dispersion profiles for stars in various nearby globular clust…
Wide binaries as a critical test for Gravity theories
X. Hernandez, M. A. Jimenez, C. Allen
Assuming Newton's gravity and GR to be valid at all scales leads to the dark matter hypothesis as a requirement demanded by the observed dynamics and measured baryonic content at g…
Non-relativistic Extended Gravity and its applications across different astrophysical scales
J. C. Hidalgo, S. Mendoza, X. Hernandez +3
Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quan…
Wide binaries as a critical test of Classical Gravity
X. Hernandez, M. A. Jimenez, C. Allen
Modified gravity scenarios where a change of regime appears at acceleration scales have been proposed. Since for systems the acceleration drops below $a_{0}…
