These stars from the early universe are made of more pristine hydrogen, a gas which makes them «Titans among stars,» at 40 to 100 solar masses.

However, the more tenuous neutral hydrogen gas slowed down substantially in the corona.

Although tentative, this correlation makes sense: the fewer metals a Jupiter - mass gas giant possesses, the more lightweight hydrogen and helium it has, so the bigger and fluffier the planet should be.

They could have condensed directly out of seed clouds of hydrogen gas weighing tens of thousands of solar masses, and grown from there by gravitationally swallowing up more gas.

The demand for coal to produce the hydrogen needed to run gas batteries has transformed places such as Grove's own south Wales, where coalfields are expanded to meet the insatiable need for more power.

Another possible explanation for the strong radio signal Bowman and the EDGES team discovered is that there's more radio background radiation being absorbed, rather than the hydrogen gas being colder than previously thought.

Planets that are smaller (i.e. 1.5 Earth radii or less) or have less hydrogen and helium early in their lives turn into dense, rocky planets with solid surfaces, while larger planets or those with more gas turn into Neptune - like planets with no discernable solid surface and thick atmospheres.

Presumably, the strong stellar wind emitted by giant stars eventually blows the titanium oxide out of the star's outer regions (along with hydrogen and helium gases and dust made of elements and molecules like carbon) into interstellar space, until vigorous convection brings out more titanium and oxygen that are created from nuclear processes deeper in the star.

Given the low abundance of elements heavier than hydrogen, moreover, it is possible that the star is more likely to have gas giants in cold outer orbits.
