Artist’s concept of a the red dwarf star known as Scholz’s star, a binary system formed by a small red dwarf, with about 9% of the mass of our sun, around which a much less bright and smaller brown dwarf orbits. According to astronomers, our ancestors saw the faint reddish light of this passing star system in the nights of prehistory. Image via Eric.
Astronomers announced new evidence on March 20, 2018 the passage of the Scholz´s star 70,000 years ago gravitationally disturbed our solar system’s comets and asteroids. The evidence still exists, these researchers say, in the movements of some of these objects marked by that stellar encounter. Their study will appear in the May 1, 2018 issue of the peer-reviewed journal Monthly Notices of the Royal Astronomical Society.
Astronomers - Scholz - Star - Team - Astronomers
Astronomers have wondered about Scholz’s star at least since 2015, when by a team of astronomers led by Eric Mamajek gave details of a possible stellar flyby, the closest documented so far, in a study in The Astrophysical Journal Letters.
The new study comes from the Complutense University of Madrid, from Carlos de la Fuente Marcos and Raúl de la Fuente Marcos (who are brothers), together with the researcher Sverre J. Aarseth of the University of Cambridge in the U.K. The researchers’ statement explained:
Time - Humans - Africa - Neanderthals - Planet
At a time when modern humans were beginning to leave Africa and the Neanderthals were living on our planet, Scholz’s star – named after the German astronomer who discovered it – approached less than a light-year from the sun. Nowadays it is almost 20 light-years away, but 70,000 years ago it entered the Oort cloud, a reservoir of trans-Neptunian objects located at the confines of the solar system.
The de la Fuente Marcos brothers, and Aarseth, analyzed the nearly 340 objects of our solar system with hyperbolic orbits. Those are orbits...
