Creation Moment 2/21/2021 - Heb.11 Clears up any "mystery" to mini-neptune origins

 How about this as an option---it clears up the "mystery" of how they came about....they were Created as is....Through faith we understand that the worlds were framed by the word of God... Hebrews 11:3

"Mini-Neptunes and super-Earths up to four times the size of our

own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away. In a new study published in The Astrophysical Journal, astronomers from McGill University show that some of these exoplanets never had gaseous atmospheres to begin with, shedding new light on their mysterious origins.

From observations, we know about 30 to 50 percent of host stars have one or the other, and the two populations appear in about equal proportion. But where did they come from?

One theory is that most exoplanets are born as mini-Neptunes but some are stripped of their gas shells by radiation from host stars, leaving behind only a dense, rocky core. This theory predicts that our Galaxy has very few Earth-sized and smaller exoplanets known as Earths and mini-Earths. However, recent observations show this may not be the case.

"Contrary to previous theories, our study shows that some exoplanets can never build gaseous atmospheres to begin with," says co-author Eve Lee.

The findings suggest that not all super-Earths are remnants of mini-Neptunes. Rather, the exoplanets were formed by a single distribution of rocks, born in a spinning disk of gas and dust around host stars."
