Knowledge of the composition of material that will form planets is crucial to understand planetary diversity and the occurrence of potentially habitable planets. Ultimately, it is the chemistry in circumstellar disks that determines the global make up of planetary systems, as the dust in these disks grows into giant planet cores and rocky planets, the gas becomes incorporated in giant planet atmospheres, and the ices can be delivered to rocky planets by comets and meteorites. With the advent of ALMA a decade ago and the recent launch of JWST, the composition of the disk gas and ice can now be studied in great detail. This review will provide an overview of our current knowledge of the disk chemical structure, focusing on the six elements essential to life on Earth: carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P) and sulfur (S).

  1. Using Scattered Near-Infrared Light to Map Water Ice in Prestellar Cores with SPHEREx

    astro-ph.GA 2026-07 conditional novelty 7.0 of 10

    Coreshine SPHEREx spectra map 3 µm H2O ice across four prestellar cores; the two densest show an unexplained central drop in ice absorption that standard Bonnor-Ebert scattering models cannot reproduce.

  2. Intracluster ion-molecule reaction in quinoline and isoquinoline dimers under the influence of diverse ionizing radiations

    physics.chem-ph 2025-06 conditional novelty 6.0 of 10

    Quinoline and isoquinoline dimers form spontaneously and, when ionized, undergo intracluster ion-molecule reactions that produce new molecular ions, potentially explaining some astrochemical growth.

  3. An Introduction to Dust Evolution and Vertical Transport in Protoplanetary Disks

    astro-ph.SR 2025-09 unverdicted novelty 1.0 of 10

    A tutorial that reviews the physics and observational methods for measuring dust sizes and vertical settling in protoplanetary disks.
