DOI: 10.1093/mnras/staa1084
Abstract: The SecularMultiple code, presented in two previous papers of this series, integrates the long-term dynamical evolution of multiple systems with any number of bodies and hierarchical structure, provided that the system is composed of nested… read more here.

DOI: 10.1093/mnras/sty2502
Abstract: We have selected archival observational data for several O and B trapezia in the Milky Way. For each of the main components of the trapezia we obtained transverse velocities from the historical separation data. With… read more here.

DOI: 10.1093/mnras/stz1585
Abstract: Massive young stellar object (MYSOs) form during the collapse of high-mass pre-stellar cores, where infalling molecular material is accreted through a centrifugally-balanced accretion disc that is subject to efficient gravitational instabilities. In the resulting fragmented… read more here.

DOI: 10.3389/fneur.2023.1128092
Abstract: Falls are the main contributor to both fatal and nonfatal injuries in elderly individuals as well as significant sources of morbidity and mortality, which are mostly induced by impaired balance control. The ability to keep… read more here.
