Descripción
We model the emergence of buoyant magnetic flux from the convection zone into the photosphere by means of 3D radiative MHD simulations using the MURaM code. In a series of simulations, we study how an initially buoyant magnetic flux tube rises in the presence of granular convection. The simulations take into account the effects of radiative energy exchange, ionization effects in the equation of state and compressibility. An emphasis of this talk is the comparison of observational diagnostics from the simulations with recent observations from Hinode SOT.

    Metal-poor ultracool dwarfs in the Euclid era
    Metal-poor ultracool dwarfs (ultracool subdwarfs, including very-low-mass stars and brown dwarfs) are tracers of the pristine chemical composition at early phases in the assembly of the Milky Way. They are poorly understood because they are extremely faint and rare. Our aims are to improve the knowledge of ultracool subdwarf candidates, to break

    Close visual binaries among planetary-mass objects in star-forming regions: the HST view
    Over the past decade, microlensing surveys in field stars and the Gaia-informed census of nearby star-forming regions have convincingly demonsrated the presence of a significant population of free-floating planetary-mass objects. The origin of these objects is still debated, with the main plausible scenarios being: the dynamical ejection from a

    Multi-epoch precise photometry from the ground: MUDEHaR, magnetic O stars and everything around
    MUDEHaR has completed its first of five years of project, and all the information is already available for exploitation. MUDEHaR is a multi-epoch photometric survey with two narrow filters in Hα and the calcium triplet window that uses T80Cam at the JAST80 telescope at Javalambre spanish astronomical observatory. It is obtaining ~50 epochs/year per
