A relevant fraction of massive stars are runaways, moving with a significant peculiar velocity with respect to their environment. Kicks from supernova explosions in binary systems or the dynamical ejection of stars from clusters can account for the runaway genesis. We have used Gaia DR3 data to study the velocity distribution of massive O and Be

In this talk I will present how the orbital motion of the Moon and artificial satellites can be used to find gravitational wave backgrounds in the microHz band. I will finish with the prospects of dedicated missions of relatively low coast and possible mould-breaking impact

Primitive asteroids are small bodies that have evolved relatively little since their formation. Their study is essential to understand the chemical composition of the early solar system and its evolution over the past 4.57 billion years. The understanding of the evolutionary processes of primitive asteroids is all the more important as these

At present, our understanding of the formation history of the MW is limited due to the complexity of observing the imprints of accretion events and of reproducing them in numerical simulations. Moreover, though being the only galaxy, in which the Galactic potential can be probed in detail, the distribution of mass in the MW, and hence of the dark

The Javalambre Photometric Local Survey (J-PLUS) is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio Astrofísico de Javalambre. The larger field of view (FoV), high spatial resolution, contiguous narrow band filters cover a wide
