A threat? Or more insolence from the snivelling mincer of words?

You are so far hoist by your own petard that no words, of yours, will
ever increase your credibility.

We only know much about one star system- ours. And in our system, the
overwhelming majority of heavy elements are in the Sun, not in the
planets. Certainly, the planets contain a much higher ratio of heavy
to light elements than the Sun, but in terms of absolute quantity of
heavy elements *in the Solar System, the planets are insignificant.

Nothing gets "spun off" when a star system forms. Material moves
inward, not outward, and denser material settles in the middle of
bodies... including the Sun.


In the formation of most all current generation and most of the
previously generated main sequence stars, the vast majority of which
being red dwarfs, should have each produced and held onto a solar
system of sufficiently heavy element planets (unless they were really
big and nasty stars to begin with, that only lasted a hundred million
or fewer years).

Are you actually suggesting that star formations offer no spin and
thus having no spare or surplus metallicity elements to get rid of?

Are you suggesting that planets form and evolve entirely independent,
without any need of a star?

Since that statement is meaningless, how could anybody rationally
comment at all?

Are you stipulating that new stars do not create their planets?

Stars have "no spare or surplus metallicity elements to get rid of".
Nothing is thrown off of stars as they form.

Our humble SETI is constantly hampered by funding problems. Which
seems odd when it has the most likely chance of confirming radio
reception from an exo-source. Just as we are discovering the
possibility of countless worlds we hamstring out best hope of finding
others at a similar and simultaneous level of technology. What a shame
they can't tap all the UFO-nuts for small change to support their
research.


Would you like to run programs in the background on your computer
to help them?

Some computers need more memory added to do this well.

Brad, stars do not "create" planets. Planets can form from material
leftover that did not form the star. For our solar system, the
relative abundances a

Hydrogen 73.46%[9]
Helium 24.85%
Oxygen 0.77%
Carbon 0.29%
Iron 0.16%
Neon 0.12%
Nitrogen 0.09%
Silicon 0.07%
Magnesium 0.05%
Sulfur 0.04%

So, there's no requirement for any main sequence star to actually
create planets?

How many trillions of wandering/rogue planets (anything below the mass
of a brown dwarf) in addition to those captured by stars, should exist
in our galaxy?

Are we talking 1e13 or more?

What percentage of stars never had any planets to begin with, nor
having captured planets?

Planets tend to form from *the planetary disks around stars* not
from material from the star itself.

Why do you think a large numbers of rogue planets? Most planets
are gravitationally bound in elliptical orbits to their stars. Have
you evidence for more than one "wandering" planet, Brad.

Science is based on observation, not your fantasies, Brad.
