Description
EXOSAT observations of the 19 Nov. 1978 and 25 Mar. 1979b gamma bursters are presented, for the 0.02 - 2.5 keV energy range. No source was detected in either case, leading to temperature upper limits for the neutron stars assumed to be present of 105- 106K. Polar cap accretion rates are constrained to values of 10-12- 10-18M_sun;/y km2. The EXOSAT non-detection of the source discovered by the Einstein satellite in the 19 Nov. 1978 error box may be explained if the burster is more distant than about 1.5 kpc.

    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

    High-resolution observations of recurrent jets from an arch filament system
    Context. Solar jets are collimated plasma ejections along magnetic field lines observed in hot (extreme-ultraviolet (EUV) jets) and cool (chromospheric surges) temperature diagnostics. Their trigger mechanisms and the relationship between hot and cool jets are still not completely understood. Aims. We aim to investigate the generation of a sequence

    KISS: Instrument Description and Performance
    Kinetic inductance detectors (KIDs) have been proven as reliable systems for astrophysical observations, especially in the millimeter range. Their compact size enables them to optimally fill the focal plane, thus boosting sensitivity. The KIDs Interferometric Spectral Surveyor (KISS) instrument is a millimeter camera that consists of two KID arrays
