Descripción
Three d Scuti stars of Praesepe cluster (BT Cnc, KW 284 and EP Cnc) seem to be at the end of the hydrogen core burning in the subgiant phase. This is supported by the fitting of isochrones to the cluster and by the larger period of their pulsations compared to the other delta Scuti stars in the cluster. After the results obtained in a joint identification of the radial modes for four less evolved delta Scuti stars, we try to find a consistent identification of the modes in these three evolved stars. BQ Cnc is another delta Scuti star in Praesepe catalogued as a double-lined spectroscopic binary. Considering different assumptions about the real position of the isolated pulsating star in the HR diagram, we present the most plausible identification of their modes according to the results obtained for the other stars.

    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
