    Flux-Calibrated Emission-Line Imaging of Extended Sources Using GTC/OSIRIS Tunable Filters
    We investigate the utility of the tunable filters (TFs) for obtaining flux-calibrated emission-line maps of extended objects such as galactic nebulae and nearby...

    Flux-Tube Model Atmospheres and Stokes V Zero-crossing Wavelengths
    First results of the inversion of Stokes I and V profiles from plage regions near disk center are presented. Both low and high spatial resolution spectra of Fe...

    Follow-up observations of extremely metal-poor stars identified from SDSS
    Context. The most metal-poor stars in the Milky Way witnessed the early phases of formation of the Galaxy, and have chemical compositions that are close to the...

    Follow-up on three poorly studied AM CVn stars
    We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV 1440, and SDSS J183131.63+420220.2. Analysing...
