    First determination of the dynamical mass of a binary L dwarf
    We present here the results of astrometric, photometric and spectroscopic observations leading to the determination of the orbit and dynamical masses of the...

    First evidence of interaction between longitudinal and transverse waves in solar magnetic elements
    Small-scale magnetic fields are thought to play an important role in the heating of the outer solar atmosphere. By taking advantage of the unprecedented high...

    First fringes with an integrated-optics beam combiner at 10 μm. A new step towards instrument miniaturization for mid-infrared interferometry
    Context. Observations of milliarcsecond-resolution scales and high dynamic range hold a central place in the exploration of distant planetary systems in order...

    First models of the s process in AGB stars of solar metallicity for the stellar evolutionary code ATON with a novel stable explicit numerical solver
    Aims: We describe the first s-process post-processing models for asymptotic giant branch (AGB) stars of masses 3, 4, and 5 M ⊙ at solar metallicity (Z = 0.018)...

    First multi-wavelength campaign on the gamma-ray-loud active galaxy IC 310
    Context. The extragalactic very-high-energy gamma-ray sky is rich in blazars. These are jetted active galactic nuclei that are viewed at a small angle to the...
  • Publication
    First observation of bald patches in a filament channel and at a barb endpoint
    The 3D magnetic field topology of solar filaments/prominences is strongly debated, because it is not directly measureable in the corona. Among various...

    First observations of the X-ray transient EXO 2030+375 with IBIS/ISGRI
    We present a first INTEGRAL observation of the 42 s transient X-ray pulsar EXO 2030+375 with IBIS/ISGRI. The source was detected during Cyg X-1 observations in...

    First results from HerMES on the evolution of the submillimetre luminosity function
    We have carried out two extremely deep surveys with SPIRE, one of the two cameras on Herschel, at 250 μm, close to the peak of the far-infrared background. We...
  • Publication
    First spectroscopic investigation of anomalous Cepheid variables
    Context. Anomalous Cepheids (ACEPs) are intermediate-mass metal-poor pulsators that are mostly discovered in dwarf galaxies of the Local Group. However, recent...
