"Throughout the article, we nickname the two stars Kronos (HD 240430) and Krios (HD 240429). In Greek mythology, Kronos and Krios were sons of the gods Uranos and Gaia. Kronos notoriously devoured all of his children (except for Zeus) to prevent a prophecy from coming true, which predicted that he would be overthrown by them one day."

"Krios and Kronos were identified as a candidate comoving star pair in our recent search for comoving stars using the proper motions and parallaxes from the Tycho-Gaia Astrometric Solution catalog (TGAS), a component of Gaia DR1. We refer the readers to this previous work (Oh et al. 2017) for a full explanation of the method behind this search..."

Miquelarena et al 2024 https://ui.adsabs.harvard.edu/abs/2024A%26A...688A..73M/abstract speak of "the benchmark pair Krios and Kronos".

Mythology

In Greek theogonic myth, Kronos acts as leader of the Titans, the pre-Olympian generation of gods who were defeated and overthrown by Zeus and his siblings. He was identified, among other, with the West Semitic god El and with Roman Saturnus, and like the latter, with a planet.

In the oldest and most influential version of the myth by Hesiod, Kronos is a son of Uranus and Gaia. On the advice of his mother, Earth, he separates the two primordial parents Heaven and Earth by emasculating his father with a dentated sickle. He then frees his siblings from Earth's body, into which Uranus had thrown the new-borns, and becomes the new king. With his sister Rheia, he fathers the Olympic gods, but devours his children immediately after birth out of fear of a male successor. Rheia manages to save only her youngest son Zeus with a ruse. She gives Kronos to swallow not her child, but a stone wrapped in diapers and carries the child to Crete, where he grows up in secret. When Zeus reaches adulthood, he forces Kronos to spit out the stone, along with his siblings, who have grown to adolescence inside their father's body. With their help, he overpowers Kronos and the Titans in a war that lasts ten years. The defeated enemies are exiled to Tartarus.
