Or maybe they weren't astronomers or if they were they were very bad ones.
Is purported to be theirs. In it they run through the Nemesis hypothesis and claim that the supernova remnant G1.9 is actually a brown dwarf about 60AU from the Sun. They base the claim on two pieces of evidence.
First they say that between 1984 and 2008, G1.9 displayed too much angular movement to be a very distant object.
Así pues tenemos dos posiciones estelares de G1.9+0.3 perfectamente diferenciadas en el transcurso de 24 años:
a. 1984 - RA 17h 45m 37s, Dec. -27:09
b. 2008 - RA 17h 48m 45s, Dec. -27:10
They are right, a change in right ascension of slightly more than 3 arcminutes in 24 years is far too great for an object 24,000 light years away. But there is a problem. The "astronomers" got their 1984 data from The MOST Galactic Centre Survey - II. New results on published supernova remnants and G2.4 + 1.4. The description of the table they used:
Table 1. This table lists (1) The Galactic cooridinates, (2) and (3) the right ascension and declination for epoch and equinox B1950.0
I cannot find the source in the "astronomers'" document for the 2008 location but if you look for yourself you will see that "Figura 7" shows that Epoch J2000 coordinates are used. So what's the problem? Two different coordinate systems are used. The difference between the coordinates amounts to slightly more than 3 arcminutes of right ascension. G1.9 is in the same place it was in 1984. What "moved" was Earth's axis, it's called precession and it has nothing to do with Nibiru or Nemesis. Quite an obvious thing for the "Spanish astronomers" to miss.
Next, they present evidence from an article titled "A 20 Year Radio Light Curve for the Young Supernova Remnant G1.9+0.3". They present radio telescope observations and claim that the fluctuations in the size of G.19 demonstrate that it cannot possibly be a supernova remnant. It gets smaller, then larger, then smaller. The problem? The MOST radio telescope is not capable of determining the size of G1.9.
The MOST observations are not at high enough resolution to detect significant changes in the size or mophology of G1.9+0.3 with time.
What was observed? The brightness of G1.9. And what did it find?
Twenty years of observations with the Molonglo Observatory Synthesis Telescope show that the young supernova remnant G1.9+0.3 has increased in brightness by 1.22 ± 0.24 0.16 per cent yr−1 between 1998 and 2007
It found that G1.9 fits the profile of a young supernova remnant.
The "Spanish astronomers" are not astronomers or they are very bad ones.
