    IAU G5 -- The GALAH survey: science goals and highlights to date
    The field of Galactic archaeology has been very active in recent years, with a major influx of data from the Gaia satellite and large spectroscopic surveys. The...

    IAU G5 talk: A massive catalogue of ultracool dwarfs identified with LAMOST DR7
    We present a sample of 734 ultracool dwarfs using LAMOST DR7 spectra, i.e., those having a spectral type of or later than M6, including an L0. All of these red...

    IAU G5 Talk: Winds of Magnetic Massive Stars
    Massive stars (at least eight times as massive as the Sun) possess strong stellar winds driven by radiation. With the advent of the so called MiMeS...

    IAU G5: "Extreme Precision Stellar Spectroscopy"
    The new generation of spectrometers designed for extreme precision radial velocities enable correspondingly precise stellar spectroscopy. It is now fruitful to...

    IAU G5: Exo-space weather: The impact of stellar activity and outflows on the escaping atmospheres of exoplanets
    Activity of cool dwarf stars can reveal itself in the form of high-energy radiation (eg, enhanced X-ray coronal emission, flares) and particles (eg, winds...

    IAU G5: Photochemistry and Chemical Inhomogeneity on Hot Giant Exoplanets
    The James Webb Space Telescope has shown us that we cannot consider exoplanet atmospheres as globally uniform objects in chemical equilibrium. On the contrary...
