Description
In order to test the calibration technique to be used on the GOLF solar oscillation resonant scattering spectrometer on the SOHO mission, observations with a modified instrument have been carried out at Izana, Tenerife since 1989. Different methods of analysing data are compared. These show that calibration by means of a magnetic modulation technique is effective in reducing the noise level in that part of the frequency spectrum where the gravity modes are to be sought.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Long-term Study of the 2020 Magnetar-like Outburst of the Young Pulsar PSR J1846-0258 in Kes 75
    Magnetar-like activity has been observed in a large variety of neutron stars. PSR J1846‑0258 is a young 327 ms radio-quiet pulsar with a large rotational power (∼8 × 10 36 erg s ‑1), and resides at the center of the supernova remnant Kes 75. It is one of the rare examples of a high-magnetic-field pulsar showing characteristics both of magnetars and

    Constraining the overcontact phase in massive binary evolution: III. Period stability of known B+B and O+B overcontact systems
    Context. Binary systems play a crucial role in massive star evolution. Systems composed of B-type and O-type stars are of particular interest due to their potential to lead to very energetic phenomena or the merging of exotic compact objects. Aims. We aim to determine the orbital period variations of a sample of B+B and O+B massive overcontact
