Mystery Object Found in Supernova's Heart (Magnetar?)
Space.com on Yahoo ^ | 7/6/06

Posted on 07/06/2006 1:40:38 PM PDT by NormsRevenge

Embedded in the heart of a supernova remnant 10,000 light-years away is a stellar object the likes of which astronomers have never seen before in our galaxy.

At first glance, the object looks like a densely packed stellar corpse known as a neutron star surrounded by a bubble of ejected stellar material, exactly what would be expected in the wake of a supernova explosion.

However, a closer 24.5-hour examination with the European Space Agency's XMM Newton X-ray satellite reveals that the energetic X-ray emissions of the blue, point-like object cycles every 6.7 hours-tens of thousands of times longer than expected for a freshly created neutron star.

It is behavior that's more commonly seen in neutron stars that have been around for several million years, researchers say.

"The behavior we see is especially puzzling in view of its young age, less than 2,000 years," said study leader Andrea De Luca of the Istituto Nazionale di Astrofisica (INAF) in Milan. "For years we have had a sense that the object is different, but we never knew how different until now," De Luca said.

The finding is detailed in the July 7 issue of the journal Science.

Novel stage?

Called 1E161348-5055, or 1E for short, the object is embedded almost in the exact center of RCW103, a supernova remnant located 10,000 light-years away in the constellation Norma. Astronomers think that 1E and RCW103 were both born in the same catastrophic event.

Like other neutron stars, which form when a star at least eight times more massive than the Sun runs out of fuel and explodes as a supernova, 1E is estimated to be only about 12.5 miles (20 km) across.

One explanation for the neutron star's strange behavior is that it might be a magnetar, an exotic subclass of highly magnetized neutron stars. Of the dozen or so magnetars that are known, however, most usually spin several times per minute-much faster than 1E.

This explanation might still work, however, if the magnetar is surrounded by a debris disk that is helping to slow down the neutron star's spin. This scenario has never been observed before and would mark the discovery of a novel stage in neutron star evolution if confirmed.

One or two?

Another explanation, scientists say, is that 1E is part of a binary system with a normal, low-mass star with only half the mass, or less, of our Sun.

Such X-ray binary systems are known, but they usually involve systems that are millions of times older than 1E.

Despite the many speculations, the short answer is that scientists simply don't yet know how to explain 1E's strange behavior.

"RCW103 is an enigma," said study team member Giovanni Bignami, director of the Centre d'Etude Spatiale des Rayonnements (CESR) in France. "When we do figure this out, we're going to learn a lot more about supernovae, neutron stars and their evolution."

It is caused by Earth's global warming. And we all know that G.W.Bush causes that.

If a star only 2000 years old behaves like stars that are believed to be millions of years older, then maybe the stars they think are millions of years older aren't that old.
Duhuh

Actually, it's really an enormous ice skater, and she hasn't pulled her arms in yet, so she's not spinning as fast as she can.

Once she pulls her arms in, things will be more normal.

Actually, this is where all the matching sock to the remaining odd socks go in the milky way when warped through space by the hyperdimensional effects of clothes dryers.

"located 10,000 light-years away in the constellation Norma."

Norma??? Uh, NormsRevenge, you wouldn't happen to be making this one up, would you? BTW, there wouldn't happen to be a constellation Al anywhere near Norma, would there?

Magnetar Found in Supernova's Heart

Not a single serious response to this major scientific discovery. Embarrassing. C'mon, people, have you got any serious guesses what they'll find when they look in the liver?

Sorry guys, this is, as the article states, an anomaly. There are many others that do not behave this way....they behave as expected. This ONE, however, is different.

Its whats left of an alien starship after an encounter with a more aggressive and more technologically advanced race.

Could be, right? I mean what F--- do these guys know?

The theory is that the start off real fast, as I am sure you understand, and then slow down.

The extension of that is that when young, they are fast, which we see is not true for all cases, all ages. Age is a guess only, as size.

They could start off slow, build up, then way later slow down.

And I read the next post and I'll go give him credit for the answer why.

Darn. Beat me to it. You may fool others but you don't fool me.

Very simple, well-known visual everyone gets.


The child is in it's pre-accretion stage. The force of it's darkness (Neutron Star) pulls in more and more matter from the circling debris field, and grows, and gets fuel from this growing matter which increases the energy, thus the speed.

Beyond a certain growth point, (size, energy, density) entropy takes back over.


...or what you said.

Just like Al Gore.
