Description
During the summer of 1978 the F Corona was observed from the ground in the near infrared at 2. and 3. in an attempt to measure the localized thermal emission from dust predicted by Peterson (1963) and several other workers. We failed to detect this emission even though our experimental errors were well below previously quoted emission values. If thermal emission peaks around the sun exist, we believe they are either much weaker or have different shapes compared to previous ones found. This result, if confirmed, will require a revision of the dynamics and physics of circumsolar dust.

    TESS and ESPRESSO discover a super-Earth and a mini-Neptune orbiting the K-dwarf TOI-238*
    The number of super-Earth and mini-Neptune planet discoveries has increased significantly in the last two decades thanks to transit and radial velocity (RV) surveys. When it is possible to apply both techniques, we can characterise the internal composition of exoplanets, which in turn provides unique insights on their architecture, formation and

    Dramatic Drop in the X-Ray Polarization of Swift J1727.8–1613 in the Soft Spectral State
    Black hole X-ray binaries exhibit different spectral and timing properties in different accretion states. The X-ray outburst of a recently discovered and extraordinarily bright source, Swift J1727.8–1613, has enabled the first investigation of how the X-ray polarization properties of a source evolve with spectral state. The 2–8 keV polarization

    Overmassive Black Holes at Cosmic Noon: Linking the Local and the High-redshift Universe
    We report for the first time a sample of 12 supermassive black holes (SMBHs) hosted by low-mass galaxies at cosmic noon, i.e., in a redshift range consistent with the peak of star formation history: z ∼ 1–3. These black holes are 2 orders of magnitude too massive for the stellar content of their hosts when compared with the local relation for
