Descripción

In recent years accurate photometric and spectroscopic observations have
provided sound evidence that Galactic Globular Clusters can not be longer
considered the prototype of Simple Stellar Populations. In this talk we
present the most recent updates concerning the empirical evidence and
discuss the theoretical framework required for interpreting observations.
Current shortcomings in the interpretation of how the multiple stellar
populations formed in a given cluster are also discussed.

    Decoding the state transition in X-ray binaries: a spectral-timing perspective
    X-ray binaries (XRBs) are binary systems where a compact object, either a black hole or a neutron star, accretes matter from a stellar companion via an accretion disc. As this material spirals in, it heats up and emits X-rays, typically exhibiting transient outburst behaviour.During these outbursts, XRBs often transition between hard states

    The delicate interplay between accretion, ejection and magnetism in neutron stars X-ray binaries
    Matter ejection, in the form of either winds or jets, is ubiquitous in accreting X-ray binaries. Although it is clear that accretion and ejection are profoundly intertwined in these types of systems, the origin and the details of such an interconnection are yet to be unraveled. This is particularly true for systems where a low-magnetized neutron

  • Sounding the treasure trove - Asteroseismology of red-giant stars and binaries systems
    Understanding stellar structure and evolution significantly impacts our understanding of the tight-knit evolution of galaxies and exoplanet systems. However, hidden behind the luminous layers of the stellar atmosphere, the deep interior of a star is eluding from direct measurements. The seismic study of waves propagating the deep interior provides
