Ann: Exploration Update, page-85

All Brian is saying is that gold and heavy elements are created in supernovas. His one minute per century per galaxy just reflects the theoretical frequency of supernova explosions (events) in our galaxy per century. I really can’t see what relavence this has to BXX. The scarcity of heavy elements in the earths crusts amd how they got there is equally applicable to all companies that explore, mine and develop them.

If you want a really interesting fact about our galaxy and gold you need look no further than the star Chi
Lupi, a chemically peculiar star in our galaxy. It contains an abundance of mercury (Hg isotope 204) more than 100,000 times the abundance found in our solar system and similarly high values for platinum and gold.

The abundance of heavy metals in stars is measured by spectra detected from the surfaces of the stars and the reason for the high abundances of heavy metals detected in the star Chi Lupi has been postulated to be because the star has a near zero rotational velocity due to its gravitational interaction with its binary star companion. The result being that the star is quiescent, meaning its upper atmosphere is unusualy stable. The result is that the balance of gravitational forces trying to push the heavy elements towards the centre of the star are balanced by the outward force of radiation pressure from the nuclear reactions occurring within the star. The heavy elements in this way are suspended in the upper atmosphere of the star where they can be detected. Stars with higher rotational energies would not give off spectra with such high heavy metal abundances as the heavy metals would be pushed down by gravity to lower levels in the star where chemical emissions of the right signature would not be able to be detected (ie any photons emitted with signatures of the right frequency to indicate atomic transitions from heavy elements would be absorbed as they tried to make their way through the upper layers of the star).

Brian Cox has about as much to do with BBX as the above interesting fact about the star Chi Lupi. Esh
