“The most significant thing we found is that terrestrial planets around certain close and wide binaries can look similar to planets around a single star,” said Jack Lissauer of the NASA Ames Research Center. Recent numerical simulations have shown that Earth-like planets, known as terrestrials, form readily in double star systems. “So we carefully eliminated all binary stars from our sample.”īut planets may be just as likely around binaries as around single stars. “A few years ago, it was thought that were a very bad site to search for planets,” says Michel Mayor of the Observatoire de Geneve. However, when out of raised curiosity I try to browse the web, I get the picture that modern simulations (here: later part of -00) contradicts naive ideas: A priori that would be a reasonable expectation, and my old (2006ish) astrobiology books doesn’t say much in that regard. I believe I’ve seen you say that a couple of times no references given. This evidence led them to theorize a pair of planets needed to be present to account for the wobble and to infer that the masses of the two planets must be at least 6 and 8 times that of Jupiter and take 16 and 5 years respectively to orbit the two stars.įrom what I understand there are models of stellar system evolution which prevent the formation of planets around such double stars. Potter and his collaborators were quick to notice that the periodic timing wasn’t regular. This pair of twin stars are so small they would fit within the radius of our Sun and orbit each other within a period of hours. This steady flow gets superheated to millions of degrees and produces copious amounts of deadly x-rays. Because the pair orbits so closely, the white dwarf never stops collecting material from its red dwarf companion. Known in polite social circles as UZ Fornacis, this eclipsing double star is anything but a friendly environment for a solar system. It would appear there’s evidence pointing towards the existence of a double planetary system where a pair of giants are at home orbiting a binary star. Stephen Potter and Encarni Romero-Colmenero from the South African Astronomical Observatory (SAAO) and their colleagues have found. Double your pleasure… Double your fun… Double twin planets found orbiting a double sun! Are you ready for the weird, true and freaky? Then check out what Drs.
