OH Mid-infrared Emission as a Diagnostic of H2O UV Photodissociation. III. Application to Planet-forming Disks
JWST gives a unique access to the physical and chemical structure of inner disks (<10~au), where the majority of the planets are forming. However, the interpretation of mid-infrared (mid-IR) spectra […]

The End Of Planet Formation
Scientists believe that planetary systems like our solar system contain more rocky objects than gas-rich ones. Around our sun, these include the inner planets – Mercury, Venus, Earth and Mars […]

Astronomers Reveal A New Link Between Water And Planet Formation
Researchers have found water vapour in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also […]

Representation Of S-process Abundances For Comparison To Data From Bulk Meteorites
Analysis of bulk meteorite compositions has revealed small isotopic variations due to the presence of material (e.g., stardust) that preserved the signature of nuclear reactions occurring in specific stellar sites. […]
