Descripción
The relations between the angular momentum (J) and the mass (M) for a sample of spiral galaxies are discussed for galaxies distributed in the rotational velocity (V) - size (R) plane. It is found that, for a given mass, Sc galaxies have larger angular momentum (~20%) than Sa. The absence of segregation in the angular momentum (J) - mass (M) plane is explained in terms of observational errors, which are greater than the expected differences in J between galaxies of equal mass and different type. The distribution of lenticular and irregular galaxies in the V-R plane is also discussed.

    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
