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…
Diffracto-Astrometry measurements: accuracy of the measuring algorithm
A. Ruelas-Mayorga, L. J. Sanchez, J. Olivares +4
We present a theoretical analysis of the measuring algorithm we use when applying the Diffracto-Astrometry technique to Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2)…
G 112-29 (=NLTT 18149), a Very Wide Companion to GJ 282 AB with a Common Proper Motion, Common Parallax, Common Radial Velocity and Common Age
A. Poveda, C. Allen, R. Costero +2
We have made a search for common proper motion (CPM) companions to the wide binaries in the solar vicinity. We found that the binary GJ 282AB has a very distant CPM companion (NLTT…
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…
The Exo-planetary System of 55 Cancri and the Titius-Bode Law
Arcadio Poveda, Patricia Lara
The recent discovery of a fifth planet bound to 55 Cancri (Fischer et. al 2007) motivated us to investigate if this exo-planetary system fits some form of the Titius-Bode (TB) law.…
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…
