  • Activity of the Jupiter co-orbital comet P/2019 LD<SUB>2</SUB> (ATLAS) observed with OSIRIS at the 10.4 m GTC

    Context. The existence of comets with heliocentric orbital periods close to that of Jupiter (i.e., co-orbitals) has been known for some time. Comet 295P/LINEAR (2002 AR2) is a well-known quasi-satellite of Jupiter. However, their orbits are not long-term stable, and they may eventually experience flybys with Jupiter at very close range, close

  • An ultra-short-period transiting super-Earth orbiting the M3 dwarf TOI-1685

    Dynamical histories of planetary systems, as well as the atmospheric evolution of highly irradiated planets, can be studied by characterizing the ultra-short-period planet population, which the TESS mission is particularly well suited to discover. Here, we report on the follow-up of a transit signal detected in the TESS sector 19 photometric time

  • ESPRESSO mass determination of TOI-263b: an extreme inhabitant of the brown dwarf desert

    The TESS mission has reported a wealth of new planetary systems around bright and nearby stars amenable for detailed characterizations of planet properties and atmospheres. However, not all interesting TESS planets orbit around bright host stars. TOI-263 b is a validated ultra-short-period substellar object in a 0.56-day orbit around a faint (V =

  • Interactions between large-scale radio structures and gas in a sample of optically selected type 2 quasars

    Context. The role of radio mode feedback in non radio-loud quasars needs to be explored in depth to determine its true importance. Its effects can be identified based on the evidence of interactions between the radio structures and the ambient ionised gas. Aims: We investigate this interaction in a sample of 13 optically selected type 2 quasars

  • Magnetic signatures on mixed-mode frequencies. I. An axisymmetric fossil field inside the core of red giants

    Context. The discovery of moderate differential rotation between the core and the envelope of evolved solar-like stars could be the signature of a strong magnetic field trapped inside the radiative interior. The population of intermediate-mass red giants presenting surprisingly low-amplitude mixed modes (i.e. oscillation modes that behave as
