Description
Near-infrared maps in the J, H, and K bands, have been obtained for the nearby flocculent spiral NGC 2403, with a linear resolution of 900 pc. Radially and azimuthally averaged profiles, and profiles in colour index are presented. The maps and the annular profiles show the presence of near-infrared spiral arms, whose contrast with the disc is determined. We are able to analyze the maps in terms of the disc component in the near IR. We have also obtained U, B, V maps with comparable resolution from which visible-infrared colour indices have been derived.

    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

    Neural calibration of imaging Stokes polarimeters
    Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of calibration Stokes vectors. These techniques are typically limited to an error on the retrieved normalized Stokes Q, U and V parameters, in the $1\times10^{-2}$ to $1\times10^{-3}$ range. This

    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
