Volatile Composition Of The HD 169142 Disk And Its Embedded Planet

by Keith CowingOctober 3, 2024October 3, 2024

The composition of a planet’s atmosphere is intricately linked to the chemical makeup of the protoplanetary disk in which it formed. Determining the elemental abundances from key volatiles within disks […]

Located in the constellation Sagittarius, the young star HD 169142 is host to a giant protoplanet embedded within its dusty, gas-rich protoplanetary disk. This artist’s conception shows the Jupiter-like planet interacting with and heating nearby molecular gas, driving outflows seen in several emission lines, including those from shock-tracing molecules like SO and SiS, and the commonly seen 12CO and 13CO.

A Surprise Chemical Find by ALMA At HD 169142 May Help Detect and Confirm Protoplanets

by Keith CowingJune 29, 2023June 29, 2023

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of […]
