We present an updated dynamical and statistical analysis of outer Oort cloud cometary evidence suggesting the sun has a wide-binary Jovian mass companion. 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. Our most restrictive prediction is that the orientation angles of the orbit normal in galactic coordinates are centered on the galactic longitude of the ascending node Omega = 319 degree and the galactic inclination i = 103 degree (or the opposite direction) with an uncertainty in the normal direction s
A Jupiter mass or larger object on a highly inclined orbit in the inner Oort cloud would most likely have formed as a small, distant binary-star like companion, e.g., by fragmentation during collapse or capture. We conclude that a model of a hypothetical wide-binary solar companion of mass 3e 10MJ orbiting at distances of 10,000 AU is no less cosmogonically plausible than is the stellar impulse scenario.

This isn't really a new hypothesis. Nemesis has been talked about for a while.
These guys, in 2006, thought that IRAS should have been able to spot it.
A Wide-binary Solar Companion as a Possible Origin of Sedna-like Objects
A Jupiter mass or larger object on a highly inclined orbit in the inner Oort cloud would most likely have formed as a small, distant binary-star like companion, e.g., by fragmentation during collapse or capture. We conclude that a model of a hypothetical wide-binary solar companion of mass ¼ 3 ¡ 10MJ orbiting at distances of ¼ 10; 000 AU is no less cosmogonically plausible than is the stellar impulse scenario.

Maybe these "new guys" have narrowed its current location down enough to be found, if its there, by WISE.

A Bayesian statistical analysis suggests that the probability of the companion hypothesis is comparable to or greater than the probability of the null hypothesis of a statistical fluke.

Comparable or greater than a null hypothesis. That means the hypothesis cannot be statistically "confirmed" but that it may be falsifiable with more data.
WISE is performing a whole sky survey (twice). If Nemesis is there, and if it's big enough, it might be found. That would confirm it. The analysis does not.

No. I haven't "disputed" the hypothesis. I've said there isn't much evidence to support it. This latest analysis (one of several) still has not done anything to confirm it, as stated in the abstract.
This has absolutely nothing to do with "Nibiru". The object they are talking about would be orbiting thousands of AU from the Sun, with a period of millions of years.
What are you talking about, "change the size of our planets"?
