Description
In this paper we illustrate some of the capabilities of the Correlation Tracker prototype developed at the Instituto de Astrofisica de Canarias used for two-dimensional, high spatial resolution, solar spectroscopy. Slit spectra have been taken, using the Correlation Tracker as a stabilizer (minimizing image motion during exposures) and as an accurate positioning device (allowing to precisely locate the entrance slit of the spectrograph at adjacent positions on the solar disc). Spectral information is obtained from several solar regions of different sizes. Granules (including some exploding ones) and intergranules are clearly resolved. Several sub-arcsecond structures are undoubtedly distinguished as well. The two-dimensional variation of several spectral quantities in the solar atmosphere is shown, demonstrating the power of this technique and its future possibilities.

    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
