The transit fitting results for KOI-1300.01. The upper right panel shows the phase-folded and contamination-corrected transit lightcurve for the planet’s circumprimary case. The gray circles are the normalized and contamination corrected flux values. The blue squares are the normalized flux values obtained from binning 800 data points at a time. The red line is the model fit to the data. The lower right panel shows the same information for the circumsecondary case. The upper left panels shows the corner plots from the MCMC sampling in the circumprimary case. The lower left shows the corner plots for the circumsecondary case. -- astro-ph.EP

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I. Fujii/L-INSIGHT [Kyoto University], Illustrator: Shinichiro Kinoshita

PIXL micro-XRF observation from the third “Apollo Temple” scan (a,b), alongside a SHERLOC WATSON color image for context (c). An RGB composite shows the areas with relative enrichment of FeOT, SO3, and SiO2 where brownish tones highlight Fe-sulfide (a). Zones of Ni enrichment are seen in yellow (b) and marked with white arrows (a,b,c). Dashed black box shows the approximate area of the PIXL scan (c). Image Credit: NASA/JPL-Caltech.

Chemical processes in molecular clouds, such as grain-surface reactions and reactions in the gas phase, yield fundamental molecules, such as water, methanol, and ammonia. After experiencing further processes induced by energetic particles such as vacuum ultraviolet (VUV) photons and cosmic rays in the pre- or protosolar nebula stage, as well as (hydro)thermal events occurring on Solar System bodies after their formation, further complex organic molecules, such as those found in Bennu, Ryugu, and carbonaceous meteorites, may have been synthesized.
