    Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b
    Context. Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital...

    Mass-metallicity relation explored with CALIFA. I. Is there a dependence on the star-formation rate?
    We studied the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral field...

    Mass-metallicity relation of dwarf galaxies and its dependency on time: clues from resolved systems and comparison with massive galaxies
    Aims: We present a new approach to study the mass-metallicity relation and its dependency on time. Methods: We used the star formation history (SFH) derived...

    Masses and ages for metal-poor stars. A pilot programme combining asteroseismology and high-resolution spectroscopic follow-up of RAVE halo stars
    Context. Very metal-poor halo stars are the best candidates for being among the oldest objects in our Galaxy. Samples of halo stars with age determination and...

    Massive star formation in the central regions of spiral galaxies
    Context: . The morphology of massive star formation in the central regions of galaxies is an important tracer of the dynamical processes that govern the...
