    First Detection of Sign-reversed Linear Polarization from the Forbidden [O I] 630.03 nm Line
    We report on the detection of linear polarization of the forbidden [O i] 630.03 nm spectral line. The observations were carried out in the broader context of...

    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...
  • Publication
    First light simultaneous triple-channel optical observations of the OPTICAM system at the OAN-SPM
    OPTICAM is a triple-band optical system developed for the 2.1 m telescope of the National Astronomical Observatory in the Sierra de San Pedro Mártir (OAN-SPM)...

    First Results from ROTES: The ROtse Telescope Eclipsing-binary Survey
    Detached eclipsing binaries (EBs) provide a unique opportunity to carry out stringent tests on stellar evolution models. The value of EBs is enhanced by their...
  • 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...

    First survey of Wolf-Rayet star populations over the full extension of nearby galaxies observed with CALIFA
    The search of extragalactic regions with conspicuous presence of Wolf-Rayet (WR) stars outside the Local Group is challenging task owing to the difficulty in...
