Descripción
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

    Model-based identification of solar coronal mass ejections using deep neural networks
    Coronal mass ejections (CMEs) are a major driver of space weather and thus can have important negative technological and social impacts. To assess their geoeffectiveness once they are ejected, it is crucial their prompt identification in coronagraph images. In the last decade, deep neural networks (DNN) have experienced enormous improvements in

    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
