    Multiple Stellar Populations in Galactic Globular Clusters: updated empirical evidence and the theoretical framework
    In recent years accurate photometric and spectroscopic observations have provided sound evidence that Galactic Globular Clusters can not be longer considered...

    Multiple stellar populations in globular clusters: Properties, origin, unsolved questions
    Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological...

    Multiplicity among massive star population
    Massive stars are often found to be in pairs. This configuration is both a blessing and a curse. From it, we can estimate their exact properties such as their...

    New Advances in Nebular Spectroscopy of Heavy Elements
    The origins of neutron(n)-capture elements (atomic number Z > 30) have historically been discerned from the interpretation of stellar spectra. However, in the...

    New channels of single and binary evolution and nucleosynthesis
    In this talk I will present the our work on an exotic group of evolved objects: post-AGB and post-RGB stars and the excellent constraints they provide for...

    New insight into the T-type planetary mass population in the Sigma Orionis cluster
    The proper characterization of the least massive population of the young Sigma Orionis star cluster is required to understand the form of the cluster mass...

    Nitrogen spectroscopy of O-type stars -- On the difficulties to derive reliable abundances
    After a brief outline on the impact of massive stars for the cosmic and galactic evolution, we highlight the role of Nitrogen as a key element to test current...

    Nova Research at Liverpool JMU
    The Astrophysics Research Institute (ARI) was established at LJMU in 1992. Today the Institute comprises around 70 staff and research students working on topics...

    On the evolution of rotation and magnetism from solar-like stars to red giants using Kepler data
    More than 40 years ago, Skumanich (1972) showed how rotation and magnetic activity decreased with the age of a solar-like star. While this result was based on...
