Orbit determination of close binary systems using lucky imaging
We present relative positions of visual binaries observed in 2009 with the FastCam 'lucky-imaging' camera mounted on the 1.5-m Carlos Sánchez Telescope at the...
Orbit of the Patroclus–Menoetius Binary System and Predictions for the 2024/2025 Mutual Events Season
We report on the ephemeris development for Menoetius, the satellite of Patroclus. Our data set consisted of ground–based and Hubble Space Telescope relative...
Orbit-based dynamical models of the Sculptor dSph galaxy
We have developed spherically symmetric dynamical models of dwarf spheroidal (dSph) galaxies using Schwarzschild's orbit superposition method. This type of...
Orbital and physical properties of planets and their hosts: new insights on planet formation and evolution
Aims: We explore the relations between physical and orbital properties of planets and properties of their host stars to identify the main observable signatures...
Orbital and Physical Properties of the σ Ori Aa, Ab, B Triple System
We provide a complete characterization of the astrophysical properties of the σ Ori Aa, Ab, B hierarchical triple system and an improved set of orbital...
Orbital and quasi-periodic optical variations in the black hole X-ray binary V404 CYG
We present 2 weeks of CCD photometry of V404 Cyg, the optical counterpart of the soft X-ray transient (SXT) GS 2023+338, taken from La Palma in 1992 July. The R...
Schwarzschild orbit-based dynamical models are widely used to uncover the internal dynamics of early-type galaxies and globular clusters. Here we present for...
Orbital elements, masses and distance of λ Scorpii A and B determined with the Sydney University Stellar Interferometer and high-resolution spectroscopy
The triple system HD158926 (λSco) has been observed interferometrically with the Sydney University Stellar Interferometer, and the elements of the wide orbit...
