Descripción
We analyze the Hα emission line profiles of the HII region populations in three disc spiral galaxies and find evidence of wing features at 40-90 km/s from the central peak in a significant fraction of regions. We explain the wing features as due to a shell expanding inside the HII region, quantify the energy involved and present two possible mechanisms to drive the expanding shell.

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on

    Rapid multiwavelength variability reveals jet emission in the black hole binary V404 Cygni in quiescence
    Spitzer Space Telescope observations of several quiescent black hole low mass X-ray binaries (LMXBs) have shown mid-infrared excesses above the emission of a companion star. The excess has been proposed to originate from either a relativistic jet or circumbinary disk. If the mid-IR originates in a jet, then it probes the region closest to the black

    Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems
    The evolution of stars and their hosting binary systems is a highly interactive process and cannot be investigated in a segregated manner. Due to the constraints drawn by stellar binarity, oscillating red-giant stars in binary systems represent a unique opportunity to study the details of the structure and evolution of stars in the advanced phases
