Bayes-based orbital elements estimation in triple hierarchical stellar systems
Constanza Villegas, Rene A. Mendez, Jorge F. Silva +1
Under certain rather prevalent conditions (driven by dynamical orbital evolution), a hierarchical triple stellar system can be well approximated, from the standpoint of orbital par…
Visual binary stars with partially missing data: Introducing multiple imputation in astrometric analysis
Ruben M. Claveria, Rene A. Mendez, Jorge F. Silva +1
Partial measurements of relative position are a relatively common event during the observation of visual binary stars. However, these observations are typically discarded when esti…
Optimality of the Maximum Likelihood estimator in Astrometry
Sebastian Espinosa, Jorge F. Silva, Rene A. Mendez +2
The problem of astrometry is revisited from the perspective of analyzing the attainability of well-known performance limits (the Cramer-Rao bound) for the estimation of the relativ…
Orbits for eighteen visual binaries and two double-line spectroscopic binaries observed with HRCAM on the CTIO SOAR 4m telescope, using a new Bayesian orbit code based on Markov Chain Monte Carlo
Rene A. Mendez, Ruben M. Claveria, Marcos E. Orchard +1
We present orbital elements and mass sums for eighteen visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr.…
