    Spectral signatures of spinning dust from grain ensembles in diverse environments: a combined theoretical and observational study
    Recent observations of anomalous microwave emission (AME) reveal spectral features that are not readily reproduced by spinning dust models. We examine how dust...

    Spectropolarimetric Evidence for a Siphon Flow along an Emerging Magnetic Flux Tube
    We study the dynamics and topology of an emerging magnetic flux concentration using high spatial resolution spectropolarimetric data acquired with the Imaging...

    Spectroscopic analysis tool for intEgraL fieLd unIt daTacubEs (SATELLITE): case studies of NGC 7009 and NGC 6778 with MUSE
    Integral field spectroscopy (IFS) provides a unique capability to spectroscopically study extended sources over a 2D field of view, but it also requires new...

    Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
    Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...

    Spectroscopic characterization of the stellar content of ultra-diffuse galaxies
    Understanding the peculiar properties of ultra-diffuse galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and...

    Spectroscopic hint of a cold stream in the direction of the globular cluster NGC 1851
    We present the results of a spectroscopic survey performed in the outskirts of the globular cluster NGC 1851 with VIsible MultiObject Spectrograph (VIMOS)/Very...

    Spectroscopic parameters for 451 stars in the HARPS GTO planet search program. Stellar [Fe/H] and the frequency of exo-Neptunes
    To understand the formation and evolution of solar-type stars in the solar neighborhood, we need to measure their stellar parameters to high accuracy. We...

    Spectroscopic study of Ceres' collisional family candidates
    Context. Despite the observed signs of large impacts on the surface of Ceres, there is no confirmed collisional family associated with this dwarf planet. After...

    Spectroscopy at the solar limb. I. Average off-limb profiles and Doppler shifts of Ca II H
    Aims: We present constraints on the thermodynamical structure of the chromosphere from ground-based observations of the Ca ii H line profile near and off the...
