The spin evolution of stars in close binary systems can be strongly affected by tides. We investigate the rotational synchronisation of the stellar components for 69 SB1 systems and 14 SB2 B-type systems in the 30 Doradus region of the Large Magellanic Cloud using observations from the VFTS and BBC surveys. Their orbital periods range from a few to

We have determined the proper motions (PMs) of 12 dwarf galaxies in the Local Group (LG), ranging from the outer Milky Way (MW) halo to the edge of the LG. We used the Hubble Space Telescope (HST) as the first and Gaia as the second epoch using the GaiaHub software. For Leo A and Sag DIG, we also used multi-epoch HST measurements relative to

The Royal Commission for AlUla (RCU) in the Kingdom of Saudi Arabia has developed a robust and sustainable framework that is aligned with the Kingdom's Vision 2030 goals including economic diversification, local job creation and skills development. The RCU is currently thriving to deliver an environmentally and historically conscientious

The PLATO stellar analysis pipeline will provide photometric rotation and activity measurements for as many observed stars as possible. This poster is aimed at presenting the scientific abilities of the rotation and activity analysis module that will be implemented in the PLATO pipeline. The strategy combines Fourier analysis, autocorrelation of

Context. Planetary nebulae (PNe) have three main components: a central star (CS), ionized gas, and dust in the nebula. Each contains critical chemical fingerprints of the PN's evolution, which serve as tracers of the evolution, nucleosynthesis, and dust production that occurred during the preceding asymptotic giant branch (AGB) phase. Aims: We aim

Context. The TOI-178 system consists of a nearby, late-K-dwarf with six transiting planets in the super-Earth to mini-Neptune regime, with radii ranging from to 2.9 R $\Earth$ and orbital periods between 1.9 and 20.7 days. All the planets, but the innermost one, form a chain of Laplace resonances. The fine-tuning and fragility of such orbital
