    Asteroid reflectance spectra from Gaia DR3: Near-UV in primitive asteroids
    Context. In the context of charge-coupled devices (CCDs), the ultraviolet (UV) region has mostly remained unexplored after the 1990s. Gaia DR3 offers the...

    Asteroids' reflectance from Gaia DR3: Artificial reddening at near-UV wavelengths
    Context. Observational and instrumental difficulties observing small bodies below 0.5 μm make this wavelength range poorly studied compared with the visible and...

    Asteroseismic masses of four evolved planet-hosting stars using SONG and TESS: resolving the retired A-star mass controversy
    The study of planet occurrence as a function of stellar mass is important for a better understanding of planet formation. Estimating stellar mass, especially in...

    Asteroseismic masses of retired planet-hosting A-stars using SONG
    To better understand how planets form, it is important to study planet occurrence rates as a function of stellar mass. However, estimating masses of field stars...

    Asteroseismology of OB stars with hundreds of single snapshot spectra (and a few time-series of selected targets)
    Imagine we could do asteroseismology of large samples of OB-type stars by using just one spectrum per target. That would be great! But this is probably a crazy...

    Asteroseismology of the Hyades red giant and planet host ɛ Tauri⋆
    Context. Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most...
