Descripción
The paper presents a new method for deriving stellar masses and distances using the theory of radiatively driven winds as presented by Kudritzki et al. (1989) and the stellar parameters derived from NLTE spectroscopic analysis. The procedure is illustrated with five stars observed in three open clusters. Comparison with evolutionary tracks indicates a possible discrepancy between the masses and helium abundances (when enhanced) derived from these tracks and those obtained by other methods.

    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

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
