Descripción
VB 10 is the smallest star known to harbor a planet according to the recent astrometric study of Pravdo & Shaklan [1]. Here we present near-infrared (J-band) radial velocity of VB 10 performed from high resolution (R~20,000) spectroscopy (NIRSPEC/KECK II). Our results [2] suggest radial velocity variability with amplitude of ~1 km/s, a result that is consistent with the presence of a massive planet companion around VB10 as found via long-term astrometric monitoring of the star by Pravdo & Shaklan. Employing an entirely different technique we verify the results of Pravdo & Shaklan.

    Witnessing the rapid growth of disk galaxies over cosmic time
    The Hubble and James Webb Space Telescopes, with their outstanding depth and spatial resolution, are opening up the possibility of studying the edges of disk galaxies over a significant cosmic time interval. This allows us to study in detail the evolution of galaxy edges over the past 8 Gyr. The edge of galaxies, understood here as the farthest

    The mysterious U-shape of colour profiles observed in ultra-deep imaging of disk galaxies
    It has been 20 years since the classification of galaxy disk types observed in deep imaging was established. These classifications, which notably consist of pure exponential, truncated, and antitruncated, have significantly enriched our understanding of the structural diversity within galaxies. Using ultra-deep imaging, most spiral galaxy profiles

    JWST and cross-correlation techniques: A faster alternative for atmospheric studies
    The application of cross-correlation techniques to JWST transmission spectra has opened an alternate pathway to study exoplanet atmospheres with JWST observations, which will contribute to pave the road for the first atmospheric studies with ELTs. JWST observed for the first time the hot-Jupiter WASP-39b on July 2022 as part of the JWST Transiting
