In 1855, Astronomers Saw Signs Of A Giant Planet Around 70 Ophiuchi. 171 Years Later, Astronomers Have Ruled It Out
Precise radial-velocity measurements found no evidence of planetary companions and ruled out Jupiter-mass worlds, the team said.

In 1855, Astronomers Saw Signs Of A Giant Planet Around 70 Ophiuchi. 171 Years Later, Astronomers Have Ruled It Out
In 1855, William Jacob argued that the binary system could be shown to obey Newton's laws of gravitation if a massive planet were orbiting it very closely. A new team has just ruled that out.
Astronomers have explored a nearby system of two stars to search for giant planets, but they have not found any of them. Nevertheless, these results may help guide future searches for smaller and rock planets, where life-friendly conditions may exist. This system, known as AB 70 Ovejoy, is about 16 light years away from Earth. [...] The post search for strange worlds around two stars 16 light years away appeared first on Digital Fapplet.
Search For Alien Worlds Narrows Around Two Stars Just 16 Light-Years Away
Astronomers have searched a nearby system with two stars for giant planets—and found none. But the result could help guide future searches for smaller, rocky worlds, including planets that might have conditions suitable for life. The system, called 70 Ophiuchi AB, lies about 16 light-years from Earth. Its two stars orbit each other, making it […]
For decades, it remained open whether 70 Ophiuchi-rich planets are hidden in the near double star, although the system has been observed since the 19th century. A new evaluation of historical measurements and high-precision radial velocities now finds no coherent planetary signal, strongly limits Jupiter planets in the inner system and nevertheless allows space for smaller worlds in the habitable zone.
