Breaking Degeneracies in Formation Histories by Measuring Refractory Content in Gas Giants

The Astrophysical Journal, 2023
Relating planet formation to atmospheric composition has been a long-standing goal of the planetary science community. So far, most modeling studies have focused on predicting the enrichment of heavy elements and the C/O ratio in giant planet atmospheres.

Geochemistry and petrogenesis of the Feshark intrusion (NE Isfahan city)

Journal of Economic Geology, 2017
Introduction Granitic rocks are the most abundant rock types in various tectonic settings and they have originated from mantle-derived magmas and/or partial melting of crustal rocks.

CRIRES+ and ESPRESSO Reveal an Atmosphere Enriched in Volatiles Relative to Refractories on the Ultrahot Jupiter WASP-121b

The Astronomical Journal
One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation.
