    A Full-Sun Magnetic Index from Helioseismology Inferences
    Solar magnetic indices are used to model the solar irradiance and ultimately to forecast it. However, the observation of such indices is generally limited to...

    A fundamental plane for field star-forming galaxies
    Context. Star formation rate (SFR), metallicity, and stellar mass are among the most important parameters of star-forming (SF) galaxies characterizing their...

    A FWHM–K2 Correlation in Black Hole Transients
    We compare {{{H}}}α emission profiles of 12 dynamically confirmed black holes (BHs) and 2 neutron star X-ray transients (SXTs) in quiescence with those of a...

    A galaxy-driven model of type Ia supernova luminosity variations
    Type Ia supernovae (SNe Ia) are used as standardizable candles to measure cosmological distances, but differences remain in their corrected luminosities which...

    A Gemini snapshot survey for double degenerates
    We present the results from a Gemini snapshot radial-velocity survey of 44 low-mass white-dwarf candidates selected from the Sloan Digital Sky Survey (SDSS)...

    A general model of x-matter
    We investigate the cosmology of x-matter with pressure, px, and density, ρx, related by px=w0ργx(w0 0). For γ >1, this x-matter behaves like a cosmological...

    A geometric distance to the supermassive black Hole of NGC 3783
    The angular size of the broad line region (BLR) of the nearby active galactic nucleus NGC 3783 has been spatially resolved by recent observations with VLTI...

    A Geometrical Height Scale for Sunspot Penumbrae
    Inversions of spectropolarimetric observations of penumbral filaments deliver the stratification of different physical quantities in an optical depth scale...

    A giant exoplanet orbiting a very-low-mass star challenges planet formation models
    Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion...
