Description
We have observed the linear polarization of 21 bright grains of the photospheric network close to the disk center. The linear polarization of Fe I 6302.5 A was always lower than 1.9 x 10-3 (referred to continuum intensity). This level of linear polarization implies a very small magnetic field inclination with respect to the vertical, which we estimate below 10 deg. Our finding is in apparent disagreement with previous studies which claim large inclinations; however, it fulfills theoretical expectations. Plage regions close to sunspots might show inclination, but isolated network elements do not.

    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
