Description
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

    Calibrating the color-redshift relation for an optimum exploitation of Euclid data
    Euclid's three dimensional reconstruction of the matter distribution in the Universe heavily relies on a proper calibration of the color-redshift relation. Getting such calibration was the motivation of the project Complete Calibration of the Color-Redshift Relation (C3R2) survey (Masters et al. 2017), with the goal of mapping the empirical

    Gas Flows in the Central Region of NGC 4593 with Muse
    Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate the role AGN play in the growth and evolution of galaxies. We use MUSE-AO optical spectra of the inner 7''. 5 × 7''. 5 of the nearby Seyfert 1 galaxy NGC 4593 to understand how gas flows in
