    Kinematic study of planetary nebulae in NGC 6822
    Context. The kinematics of planetary nebulae in external galaxies and in our own is a clue for understanding the behavior of the low- and intermediate-mass...

    Las galaxias satélite podrían seguir formando estrellas cuando pasan cerca de las galaxias anfitrionas
    Históricamente los científicos han creído que una vez que las galaxias satélite pasan cerca de la galaxia anfitriona, de mayor masa, su formación estelar se...

    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...

    Massive OB stars at varying Z
    Massive stars play a key role in environments with very different metallicities. To interpret the role of massive stars in these systems we have to know their...
