The Exoplanets That Never Were

StartsWithABang writes In 1992, scientists discovered the first planets orbiting a star other than our Sun. The pulsar PSR B1257+12 was discovered to have its own planetary system, and since then, exoplanet discoveries have exploded. But before that, in 1963, decades of research led to the much-anticipated publication and announcement of an exoplanet discovered around Barnard's star, the second-closest star system to Earth. Unfortunately, it turned out to be spurious, and it took years to uncover, an amazing story which is only now fully coming to light.

More like accidentally kill 100,000 civilians and threaten to cut off anyone in the press corps who dares to bring it up.

there is a 100k civilians left in Syria? I thought assad killed almost anyone not actively fighting for or against him.

Not like we haven't before.

So close, and yet so far away.

You know, we're right on the verge of possessing the technology of an advanced, universe exploring, sentient life form.

Keep that in mind for perspective when the next beheading video hits the internet.

Technological advances don't imply moral advances.

Yea, and yet those evil people in Taiji keep killing them. Its our job to protect the dolphins so can explore the universe. We certainly aren't.

Red dwarfs form from so little matter

[jfdavis668]

I'm not surprised that there are no planets. Red dwarfs form from very small amounts of matter, and don't have the luminosity or stellar wind to stop the in-fall of matter into the central star. I don't doubt they can form, the same way double stars form, but the odds are lower. Just a lot less initial material to start with.

Given that we've discovered planets everywhere we never expected planets to be, being "not surprised" at not finding planets is pretty weird. The damned things are everywhere!

Exoplanets are everywhere and the astronomers keep jacking up all our classic science fiction novels set in the neighborhood by revealing the actual layout of the systems...

The star in question is Barnard's Star, a red dwarf.

Pulsar PSR B1257+12 was credited in the summary as an example at the start of the modern explosion in discovering extrasolar planets, not the one that was mistakenly thought to have planets.

Given that Red Dwarves (Dwarfs?) are like large jupiters and jupiter has moons, why would a Red Dwarf not have moon-like objects? Whether we call them planets or moons is just a matter of classification.

Re:

[jfdavis668]

In the case of Jupiter, the original gas cloud is falling toward the Sun. Once the Sun becomes a protostar, the solar wind and light pressure pushes the infalling gas back out, away from the Sun, and toward Jupiter. A red dwarf generates far less wind and light pressure, and there is less stuff to start with. It doesn't mean that planets can't form, it just lowers the probability.

Re:

If we ignited Jupiter, what would happen to the moons orbiting it? Hmm, they would be consumed. That's why red dwarves (hi ho!) have no planets around them.

But there are examples of exoplanets orbiting Red Dwarfs. Google is your friend.

Amazing story

I am not sure "amazing story" is something else than marketing here :-)

Most Compelling Reason to Doubt "Consensus"

[fygment]

Science is full of stories like this.
Someone presents a result that catches the imagination. They achieve "great scientific stature".
Someone else quesions the result. They are pilloried while the "consensus" sides with the person of "great scientific stature".
But if there is persistence, sometimes the person of "great scientific stature", and by extension, the "consensus" is proven wrong.

The lesson: "consensus" is meaningless in science. It is desctructive, politically-driven artifact that inhibits the d

ANNNNNND of course you're modded Flamebait.

I guess you hit a nerve.
