“Believed to be a dwarf galaxy, this galactic precursor consists of billions of stars.”
CORROBORATED
Sources describe Loki as a dwarf galaxy and discuss the nature of dwarf galaxies as systems of stars; while 'billions' is a general descriptor for galaxies, the context of it being a dwarf galaxy precursor is supported.

web search NEUTRAL — Galaxies grow by absorbing smaller systems. Over time, those systems lose their structure. Their stars disperse and become part of the larger galaxy. Loki fits this pattern.

“Metal-poor stars are objects that formed early in cosmic history and retain the chemical DNA of the environments in which they were born.”

“They found that the compositions and orbital behavior of these particular stars differed from that of the region’s other metal-deficient stars.”
CORROBORATED
The evidence for the Loki study indicates that the 20 stars were identified specifically because their chemical fingerprints and orbits differed from other stars in the region.
