    Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
    Context. Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and...

    Constraining cosmic rays and magnetic fields in the Perseus galaxy cluster with TeV observations by the MAGIC telescopes
    Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that...
  • Publication
    Constraining magnetic-activity modulations in three solar-like stars observed by CoRoT and NARVAL
    Context. Stellar activity cycles are the manifestation of dynamo process running in the stellar interiors. They have been observed from years to decades thanks...
  • Publication
    Constraining nuclear star cluster formation using MUSE-AO observations of the early-type galaxy FCC 47
    Context. Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs...
  • Publication
    Constraining planet structure and composition from stellar chemistry: trends in different stellar populations
    Context. The chemical composition of stars that have orbiting planets provides important clues about the frequency, architecture, and composition of exoplanet...
  • Publication
    Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems. A census of oscillating red giants and dwarf stars in Gaia DR3 binaries
    Context. Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems containing at least...
  • Publication
    Constraining the magnetic vector in the quiet solar photosphere and the impact of instrumental degradation
    Context. With the advent of next generation high resolution telescopes, our understanding of how the magnetic field is organized in the internetwork (IN)...
  • Publication
    Constraining the nature of high frequency peakers. II. Polarization properties
    Aims:The “bright” High Frequency Peakers (HFPs) sample is a mixture of blazars and intrinsically small and young radio sources. We investigate the polarimetric...
  • Publication
    Constraining the overcontact phase in massive binary evolution. II. Period stability of known O+O overcontact systems
    Context. Given that mergers are often invoked to explain many exotic phenomena in massive star evolution, understanding the evolutionary phase directly...
