  1. 264. Studies of star-forming filamentary clouds
    Mika Juvela

    Oral

    Stars form mainly in filamentary molecular clouds. This makes it important to determine, how these cloud filaments form, accrete matter, and fragment into pre-stellar cores. Accretion will continue even in later stages, associated with the protostars that are born in the cores. During the star formation, also the properties of the interstellar gas and dust evolve. This affects the cloud...

  2. 265. FEAST: A NIRSpec/MOS survey of emerging young star clusters in NGC 628
    Helena Faustino Vieira (Stockholm University)
    27/05/2026, 13:30
    Oral

    The star formation process is at the center of the baryonic cycle, dictating galaxy evolution and setting the stage for planet formation. Feedback from massive stars injects momentum, energy and metals into the natal cloud, kickstarting the emergence process of young star clusters. JWST can pierce through the dusty interstellar medium and reveal the feedback-driving emerging young star...

  3. 266. The emerging timescale of young star clusters in local galaxies
    Alex Pedrini (Stockholm University)
    27/05/2026, 13:45
    Oral

    The interplay between massive stars and the interstellar medium (ISM) during the embedded phase of star formation is a key driver of the physical, chemical, and morphological evolution of galaxies. As young star clusters emerge from dense, dusty gas clouds due to feedback from their massive stars, they inject large amounts of energy and momentum into their surroundings, shaping the local ISM...

  4. 267. Metal-poor stars as witnesses for the first steps of the Milky Way assembly history
    Anastasiia Plotnikova (Lund University)
    27/05/2026, 14:00
    Oral

    How old is the Universe? What happened to the Milky Way at the very beginning of its formation? To answer these questions, we analyze a sample of 28 extremely metal-poor field stars in the solar vicinity. We determine their ages and kinematical properties, and combine these together with their chemical composition to study their origin. The mean age of the sample is 13.8 ± 0.5 Gyr, suggesting...

  5. 268. From Carbon to Ytterbium: Infrared Chemistry of Open Clusters Across the Milky Way Disc
    Shilpa Bijavara Seshashayana (Malmö University)
    27/05/2026, 14:15
    Oral

    Open clusters provide robust constraints on Galactic chemical evolution because their member stars have well defined ages, Galactic birth radii, and a shared chemical baseline. This homogeneity enables high precision constraints by averaging abundances across multiple stars within the same cluster, reducing the impact of star to star scatter and measurement uncertainties. However, the...
