    Revisiting the hypothesis of purely stochastic excitation of global p modes in the Sun
    Context. In solar-like oscillators, acoustic waves are excited by turbulent motion in the convective envelope and propagate inward, generating a variety of standing pressure modes (p modes). When combining the power of several solar acoustic modes, some studies have reported an excess that is not compatible with pure stochastic excitation. This

    Red supergiant stars in binary systems: II. Confirmation of B-type companions of red supergiants in the Small Magellanic Cloud using Hubble ultraviolet spectroscopy
    Red supergiant (RSG) stars represent the final evolutionary phase of the majority of massive stars and hold a unique role in testing the physics of stellar models. Eighty-eight RSGs in the Small Magellanic Cloud (SMC) were recently found to have an ultraviolet (UV) excess, which was attributed to a B-type companion. We present follow-up Hubble

    Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT
    The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and (2) a leptonic extended component peaking at the solar edge and extending into the heliosphere. The flux of these components is expected to vary with the 11 yr solar

    Puzzling radial gradients of K-band absorption features in the giant elliptical galaxy M87
    We present new K-band spectroscopy for the giant elliptical galaxy M87 in the Virgo cluster, taken with the Large Binocular Telescope Utility Camera in the Infrared (LUCI) spectrograph at the Large Binocular Telescope (LBT). The new data are used to study line strengths of K-band absorption features from different chemical species, namely Fe, Mg

    NIRPS joining HARPS at ESO 3.6 m: On-sky performance and science objectives
    Context. The Near-InfraRed Planet Searcher (NIRPS) is a high-resolution, high-stability near-infrared (NIR) spectrograph equipped with an adaptive optics (AO) system. Installed on the ESO 3.6-m telescope at La Silla Observatory, Chile, it was developed to enable radial velocity (RV) measurements of low-mass exoplanets around M dwarfs and to

    NIRPS detection of delayed atmospheric escape from the warm and misaligned Saturn-mass exoplanet WASP-69 b
    Context. Near-infrared high-resolution échelle spectrographs unlock access to fundamental properties of exoplanets, from their atmospheric escape and composition to their orbital architecture, which can all be studied simultaneously from transit observations. Aims. We present the first results of the newly commissioned ESO near-infrared
