Description
Results are presented for the sun's radial velocity in integrated sunlight. A resonant scattering spectrometer has been used to determine the frequencies and amplitudes of p-modes with spherical harmonics of degree (l) of less than 3, and a second spectrophotometer, which observes part of the sun by means of a spatial filter, has been used to measure the frequencies and amplitudes of p-modes with l of not greater than 5. The frequencies at both ends of the p-mode 5-minute oscillations with l of between 3 and 5, inclusively, are obtained with greater precision than previous determinations.

    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

    Counting stars from the integrated spectra of galaxies
    Over the last few decades, evolutionary population synthesis models have powered an unmatched leap forward in our understanding of galaxies. From dating the age of the first galaxies in the Universe to providing detailed measurements of the chemical composition of nearby galaxies, the success of this approach built upon simple stellar population

    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
