Description
We present a study of the metallicity of 20268 galaxies from the Sloan Digital Sky Survey—Data Release 6 (SDSS-DR6)—using the R 23 method, and derive analytical calibrations from several metallicity-sensitive line ratios: [Nii] λ6583/Hα, [Oiii] λ5007/[Nii] λ6583, [Nii] λ6583/[Oii] λ3727, [Nii] λ6583/ [Sii] λλ6717, 6731, [Sii] λλ6717, 6731/Hα, and [Oiii] λλ4959, 5007/Hβ. We have performed the study for the resdshift interval (0.04-0.1) for all the Sloan survey release. This is the first part of a more complete work which aims to study the metallicity dependences of the star-forming galaxies in the Local Universe.

    Convection, rotation, and magnetic activity of solar-like stars from asteroseismology
    During the last decade, our understanding of stellar physics and evolution has undergone a tremendous revolution thanks to asteroseismology. Space missions such as CoRoT, Kepler, K2, and TESS have already been observing millions of stars providing high-precision photometric data. With these data, it is possible to study the convection of stars

    Tales of stellar & binary co-evolution, told by stellar oscillations
    Stellar binarity and stellar oscillations are mostly seen and studied as two separate phenomena. Sometimes, one process is even complicating the analysis of the other beyond the liking of one or the other research community. However, the complete picture painted by the physical constraints provided by the combination of both processes represents a
