Description

Spectroscopy is a powerful tool to unravel the nature of stellar bodies. For instance, spectra can be used to derive the temperature, gravity, and chemical composition at the surface of a star. If the star is part of a binary system and/or pulsating, spectra can even tell us something about its fundamental parameters mass and radius. In this talk, I will illustrate the opportunities and difficulties related to studying the spectra of pulsating stars or stars in binary systems, with special focus on massive stars of spectral type B.

    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

  • Colloquium
    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
