Survey of Over 800 Planet-Forming Disks Finds Planetary Evolutionary Surprise

Astronomers can calculate the total mass of planets by measuring the disks’ mass around young stars

We still don’t know which properties affect the evolution of planet-forming disks around young stars.

“Our new results now indicate that in environments without any relevant external influence

, the observed disk mass available for forming new planets only depends on the age of the star-disk system.”

The age of the star and its disk, dynamics of the parent cloud, and the chemical properties

all combined with mass give a clear picture of the solar system that arises from the disk

Astronomers aren’t able to record data like this and predict what type of planets might form in any given Solar System.
