    An Empirical Criterion to Classify T Tauri Stars and Substellar Analogs Using Low-Resolution Optical Spectroscopy
    We have compiled and studied photometric and spectroscopic data published in the literature of several star-forming regions and young open clusters (Orion...

    An Empirical Procedure to Estimate Distances to Stellar Clusters
    A most desirable feature of a standard candle to estimate astronomical distances is robustness against changes in metallicity and age. It is argued that the...

    An Empirical Relation between the Large-scale Magnetic Field and the Dynamical Mass in Galaxies
    The origin and evolution of cosmic magnetic fields as well as the influence of the magnetic fields on the evolution of galaxies are unknown. Though not without...

    An empirical, Bayesian approach to modelling crop yield: Maize in USA
    We apply an empirical, data-driven approach for describing crop yield as a function of monthly temperature and precipitation by employing generative...

    An enhanced slope in the transmission spectrum of the hot Jupiter WASP-104b
    We present the optical transmission spectrum of the hot Jupiter WASP-104b based on one transit observed by the blue and red channels of the Double Spectrograph...

    An enquiry on the origins of N-rich stars in the inner Galaxy based on APOGEE chemical compositions
    Recent evidence based on APOGEE data for stars within a few kpc of the Galactic Centre suggests that dissolved globular clusters (GCs) contribute significantly...

    An equatorial outflow in the black hole optical dipper Swift J1357.2-0933
    We present high time resolution optical spectroscopy and imaging of the black hole transient Swift J1357.2-0933 during its 2017 outburst. The light curves show...

    An equatorial ultra iron-poor star identified in BOSS
    We report the discovery of SDSS J131326.89-001941.4, an ultra iron-poor red giant star ([Fe/H] ≃ -4.3) with a very high carbon abundance ([C/Fe] ≃ +2.5). This...
