Description
A study has been undertaken of the physical conditions of the ionized gas within the starburst region of the galaxy NGC 253, using long slit spectroscopy at high spatial and spectral resolution. The aim was to identify the appropriate parameters describing the dynamics of the gas and the excitation conditions, in relation with the starburst process. Non-Gaussian line profiles and line splitting are clearly observed, indicating a complicated dynamical structure; furthermore, the zones presenting noncircular motions and localized outflow of gas have been spatially sampled at the seeing limit.

    Massive characterisation of subgiants and red giants with TESS (Kepler and Gaia)
    TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

    a Study of Post-Agb Stars in the Light of GAIA DR3 Data
    Low and intermediate-mass stars evolve through the Post Asymptotic Giant Branch (post-AGB) phase before they reach the Planetary Nebulae stage. After leaving the Main Sequence, they undergo intense episodes of mass loss when in the Giant Branch and, then, they enter the post-AGB stage which is a rather puzzling stellar evolutionary phase . Also, it
