Description
Results are presented from a search for variations in solar granulation properties with heliographic latitudes. Photographs taken in the summers of 1985 and 1986 are used to study the power spectra in the direction perpendicular to the solar radius. It is found that there are no important differences in the power spectra obtained for positions along the equator and those obtained for positions along the rotation axis. It is shown that the size of granules remains constant at different heights of the solar photosphere in both the N-S and the E-W directions.

    Co-phasing the distributed aperture of a Fizeau interferometer via photonic lanterns and machine learning
    The advantage of large optical telescopes from the ground for high-contrast direct imaging relies on achieving exquisite control of the incident optical wavefront. Since the exoplanet problem almost always has a bright star within a small field of view there are usually ample photons for measuring the atmospheric and telescopedistorted wavefront. A

    Unveiling Chiron, an odd ice ball, with Webb: Ice and Gas Phases Revealed
    We present unprecedented findings on (2060) Chiron using James Webb Space Telescope (JWST) NIRSpec imaging and spectroscopy from cycle 1 GTO program 1273. Our study (Pinilla-Alonso et al. 2024 A&A Letter) marks the first detection of carbon dioxide (CO 2) and methane (CH 4) active outgassing and coma emission at heliocentric distances of ~18 au

    Conceptual optical design of the infrared integral field spectropolarimeter for the European Solar Telescope
    The European Solar Telescope (EST), with its primary mirror of 4.2 diameter, will be the largest solar telescope available in Europe. EST will offer Integral Field Spectropolarimetry (IFS) by incorporating the EST spectropolariMeter Based on slicEr-mirrors for the near-infraRed (EMBER). This instrument is a high-resolution spectropolarimeter that
