    Strategy for the Inversion of Hinode Spectropolarimetric Measurements in the Quiet Sun
    In this paper we propose an inversion strategy for the analysis of spectropolarimetric measurements taken by Hinode in the quiet Sun. The Spectro-Polarimeter of...

    Studying the accretion geometry of EXO 2030+375 at luminosities close to the propeller regime
    The Be X-ray binary EXO 2030+375was in an extended low-luminosity state during most of 2016. We observed this state with NuSTARand Swift, supported by...

    Submillimeter Polarization Spectrum in the Vela C Molecular Cloud
    Polarization maps of the Vela C molecular cloud were obtained at 250, 350, and 500 μm during the 2012 flight of the balloon-borne telescope BLASTPol. These...

    Submillimeter Polarization Spectrum of the Carina Nebula
    Linear polarization maps of the Carina Nebula were obtained at 250, 350, and 500 μm during the 2012 flight of the Balloon-borne Large Aperture Submillimeter...

    Sunspot seismic halos generated by fast MHD wave refraction
    Aims: We suggest an explanation for the high-frequency power excess surrounding active regions known as seismic halos. Methods: We use numerical simulations of...

    Supersonic Continuation of the Evershed Flow Outside a Sunspot as Observed with Hinode
    We report on the discovery of mostly horizontal field channels just outside sunspot penumbrae (in the so-called "moat" region) that are seen to sustain...
