Protoplanet Archives

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.

The Dynamic Proto-atmospheres Around Low-Mass Planets With Eccentric Orbits

by Keith CowingJuly 9, 2020

Protoplanets are able to accrete primordial atmospheres when embedded in the gaseous protoplanetary disk. The formation and structure of the proto-atmosphere are subject to the planet–disk environment and orbital effects. […]
