Descripción
The authors report photoelectric and CCD photometry of V651 Mon, the central star of the planetary nebula NGC 2346, made in April - May and November, 1992. During each of these two epochs an occultation was measured, of amplitude 0.20 and 0.35 in the observed V magnitude, in accordance with previous results. These variations may be interpreted in terms of other fragmented dust cloud(s) passing in front of the binary central star, but probably an additional source must be invoked.

    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

    Unsupervised classification of RR Lyrae stars
    Big datasets are becoming increasingly important in astrophysics due to new surveys continuously observing our night sky. A prominent example of an observatory that will produce a large data stream is Vera C. Rubin LSST, designed to simultaneously monitor the southern night sky in six colors. Unsupervised machine learning (ML), a method of learning
