Descripción
We present the results of two studies of the inner Galaxy : on the one hand, a maximum likelihood fitting method using the Besançon model of Galaxy to constrain the density laws of the outer bulge and the holed disc; on the other hand, the comparison of Besançon simulations with infrared data on fields near longitude 20 27 degrees to verify the existence of a long and thin in-plane bar. These two parallel studies seem to show the co-existence of a structure (the bar) in addition with a very oblate outer bulge.

    ALISIO-1 mission: bridging space and Earth with next-generation CubeSat for optical communications and environmental monitoring
    ALISIO-1, the first satellite owned and led by the Instituto de Astrofısica de Canarias (IAC), represents a significant milestone in the space exploration of the Canary Islands. This 6U CubeSat, whose platform has been developed by Open Cosmos, carries two novel payloads: DRAGO-2 and CubeLCT. DRAGO-2, a Short-Wavelength Infrared (SWIR) camera, is

    From atmospheres to exospheres in exoplanets
    Interaction phenomena between atmospheric layers in planetary atmospheres give rise to highly complex exchanges influencing thermal structure, composition and dynamics. In particular, the question of hydrodynamic escape in exoplanet atmospheres is a key issue for quantifying the mass loss in these atmospheres. Short-period exoplanets subject to
