To help mitigate popular confusion with the Nemesis model (Whitmire and Jackson ( 1984), Davis et al. ( 1984)) we use the name recently suggested by Kirkpatrick and Wright (2010), Tyche, (the good sister of Nemesis) for the putative companion.
I posted a couple of articles and quoted a member of the WISE team who directly contradicts stereologist's assertion that they didn't change the name from "Nemesis" to "Tyche."
There is some speculation amongst scientists that such a cool body, if it exists, could be a brown dwarf companion to our sun. This hypothetical object has been nicknamed "Nemesis."
"We are now calling the hypothetical brown dwarf Tyche instead, after the benevolent counterpart to Nemesis," said Kirkpatrick.
The results support a conjecture that there exists a companion of mass ~ 1-4 M_Jup orbiting in the innermost region of the outer Oort cloud.

At this point the search for Nemesis is over since that property, the supposed periodic nature of extinctions, did not pan out.
OK, there's evidently two different versions of the Nemesis/Tyche naming scheme, which I find suspicious in itself. You're quoting from the astronomer's abstract and I'm quoting from a NASA article and WISE team member. In any case, according to the article, both are brown dwarfs. My whole point is, the name keeps changing, whether it's Planet X, Nemesis or Tyche, not to mention the plethora of "unofficial" names such as Nibiru, Wormwood, Hercolubus, etc. But ALL of them are brown dwarfs and some of these references go way back to the Sumerian tablets and Kolbrin Bible. I find it highly improbable that these could be different objects.
How can you state this with such certainty, especially when the data hasn't been analyzed and a search for "Nemesis" was a stated primary goal of WISE?
I've edited my previous post to acknowledge that there are two different versions of the Nemesis/Tyche naming scheme.
Stereologist, if you can prove me beyond all doubts Sumerians did know a lot about space, it would be appreciated. To me that's just speculation you're doing. How can we expect to be so sure about an ancient civilization...
And to correct YOUR misrepresentation of Nemesis... it is just a name given to ONE theory
since MOST systems are binary.
AND Nemesis has also been used to describe the SAME star in a NON-EXTINCTION fashion, as in to relate it to the SISTER star of our sun that may or may not have been a star or could be floating around outside of the Oort Cloud.
This specific thread is dealing with a "new" discovery about a potential planetary body that just coincidentally matches some of the stories around Planet X.
Vulcan, Persephone, or Clarion
