Descripción
We report detection of the binary companion to the millisecond pulsar J1741+1351 with the Gran Telescopio Canarias. The optical source position coincides with the pulsar coordinates and its magnitudes are g′ = 24.84(5), r′ = 24.38(4) and i′ = 24.17(4). Comparison of the data with the WD evolutionary models shows that the source can be a He-core WD with a temperature of ≈ 6000 K and a mass of ≈ 0.2M☉. The latter is in excellent agreement with the companion mass obtained from the radio timing solution for PSR J1741+1351.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta
