Description
We performed an extensive observing programme on the zodiacal light with ISOPHOT. The mapping of several ~0.5degx0.5deg fields demonstrates the sub-percentage smoothness of the zodiacal light brightness on arcminute scale. The analysis of 27 ISOPHOT-S spectra in the 5-12μm range revealed blackbody-like spectral shapes with no obvious spectral features. The derived temperatures increase with ecliptic latitude and decrease with distance from the Sun in the range of 260-290 K. New interesting results are expected from multifilter photometry of the interplanetary dust cloud, and from observations of the asteroidal bands as well as of a cometary dust trail.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
