If Nemesis exists, it may be detected by Pan-STARRS or the planned LSST astronomical surveys.
Development of the Nemesis hypotheses Two teams of astronomers, Daniel P. Whitmire and Albert A. Jackson IV, and Marc Davis, Piet Hut, and Richard A. Muller, independently published similar hypotheses to explain Raup and Sepkoski's extinction periodicity in the same issue of the journal Nature. This hypothesis proposes that the Sun may have an undetected companion star in a highly elliptical orbit that periodically disturbs comets in the Oort cloud, causing a large increase of the number of comets visiting the inner Solar System with a consequential increase of impact events on Earth. This became known as the "Nemesis" or "Death Star" hypothesis. If it does exist, the exact nature of Nemesis is uncertain. Muller suggests that the most likely object is a red dwarf with an apparent magnitude between 7 and 12, while Daniel P. Whitmire and Albert A. Jackson argue for a brown dwarf. If a red dwarf, it would exist in star catalogs, but it would only be confirmed by measuring its parallax; due to orbiting the Sun it would have a low proper motion and would escape detection by older proper motion surveys that have found stars like the 9th-magnitude Barnard's star. (The proper motion of Barnard's star was detected in 1916.) Muller expects Nemesis to be discovered by the time parallax surveys reach the 10th magnitude. Muller, referring to the date of a recent extinction at 11 million years before the present day, posits that Nemesis has a semi-major axis of about 1.5 light-years (95,000 AU) and suggests it is located (supported by Yarris, 1987) near Hydra, based on a hypothetical orbit derived from original apogees of a number of atypical long-period comets that describe an orbital arc meeting the specifications of Muller's hypothesis. Richard Muller's most recent paper relevant to the Nemesis theory was published in 2002. In 2002, Muller speculated that Nemesis was perturbed 400 million years ago by a passing star from a circular orbit into an orbit with an eccentricity of 0.7.
Recently, scientists have counted on Pleiades for generating the "Bolshoi" cosmological simulation—the largest simulation of its kind to date—to help explain how galaxies and the large-scale structure of the universe have evolved over billions of years. The system has also proven essential for processing massive amounts of star data gathered from NASA's Kepler spacecraft, leading to the discovery of new Earth-sized planets in the Milky Way galaxy. The upgraded capability of Pleiades will enable NASA scientists to solve challenging problems like these more quickly, using even larger datasets.

Actually most of the stars we are now able to see with telescopes are red dwarfs. Red dwarfs are much more likely to appear in single star systems. Furthermore, we can look at our own galactic neighborhood. Most stars in our section of the Milky Way are also single star systems. It's also a fact that if a yellow dwarf (like our Sun) is in a multi-star system its partner(s) are most likely going to be other yellow dwarfs. If there were another yellow dwarf in the solar system it would be readily apparent. With the technology we have now and with the number of whole sky surveys that have been performed, along with the facts above, it is almost impossible at this point for our Sun to have a hidden companion.
I love your signature, it just is so hypocritical coming from someone that writes what you do... and I shall explain why.
There has been no evidence, in any shape or form to suggest that we live in a Binary Star System, nor is there any evidence to lend credence to the existence of another system out there that in any way effects our own planetary system.
What i find amusing in all this is thusly:
1) Depending on the argument Nibiru changes from a planet, to a star, to a dark star (that noone can see) to a brown dwarf (that is only seen in IR film) to a large gas giant etc etc.
2) not one person can agree on what Nibiru is or isn't, seems to have so many different forms depending on what line of thought a person needs to take to counter the rational thinking crowd.
3) Nibiru people claim there's some vast conspiracy to silence anyone from talking about this planet however, noone can prove the existence of one, or the validity of the Nibiru theory, other than to attack and call anyone who doesn't believe "low level" or "Hey I guess you won't make the shift" or "Your vibrations aren't high enough to understand"
So truth time sir/madam... Planet X theory was all started by a guy named Stichen, in 1995 a really delusional woman named Nancy Lieder re-introduced the theory as a way to get attention, and get out some messages that she claims was sent to her by Zetas. Nancy has been proven wrong so many times over that it's not funny.
And finally, the word Nibiru itself, does not refer to an ancient planet or anything of the like, it is literally translated as:
A crossing, usually in a river or road, in astronomy the crossing of planets causing eclipses..
So.. where's the mystery planet now? If you are really interested in the truth, then you may wish to hone up on your Sumerian.. and not use Stichen's misinterpretations..

Once again you fail to account for amateur astronomers. One doesn't even need to own a telescope these days. They can rent time on large professional satellites with no strings attached. I mean they can find tiny comets out by Saturn before they start outgassing. Do you really think they wouldn't be able to spot a planet/star that's supposed to be here by the end of the year? I feel this comment also need to be addressed:
Radio telescopes being built in the southern hemisphere (hmmm, to track IR?).
Please explain how a radio telescope is going to detect something in the IR spectrum. A radio telescope doesn't view things in the visual spectrum. As the word radio suggests its based on sound. IR on the other hand stands for infrared. It exists in the visual spectrum. Thus a radio telescope cannot do anything involving IR. Now a radio telescope can detect objects that are also visible in the IR range but it is not going to "track IR."
Lastly, it is harder for you to prove that Nemesis & Nibiru DO NOT exist, than it is for Me to prove they do !
Nemesis is the Red Dwarf star that planet Nibiru rotates around, with other planets in its system. That is what is.
