‘Lopsided’ Supernova Could Be Responsible for Rogue Hypervelocity Stars

Hypervelocity stars have been observed traversing the Galaxy at extreme velocities (700 km/s), but the mechanisms that give rise to such phenomena are still debated. Astronomer Thomas M. Tauris argues that lopsided supernova explosions can eject lower-mass Solar stars from the Galaxy at speeds up to 1280 km/s. “[This mechanism] can account for the majority (if not all) of the detected G/K-dwarf hypervelocity candidates,” he said.

Several mechanisms have been proposed as the source for hypervelocity stars, and the hypotheses can vary as a function of stellar type. A simplified summary of the hypothesis Tauris favors begins with a higher-mass star in a tight binary system, which finally undergoes a core-collapse supernova explosion. The close proximity of the stars in the system partly ensures that the orbital velocities are exceedingly large. The binary system is disrupted by the supernova explosion, which is lopsided (asymmetric) and imparts a significant kick to the emerging neutron star. The remnants of supernovae with massive progenitors are neutron stars or potentially a more exotic object (i.e., black hole).

There are several potential compact objects (neutron stars) which feature extreme velocities, such as B2011+38, B2224+65, IGR J11014-6103, and B1508+55, with the latter possibly exhibiting a velocity of 1100 km/s.

What would happen if an extreme velocity neutron star entered our solar system?

Short answer; it would suck.

LOL.
He hails from T Tauri.

Of interest, PING

[mikrofon]

+!

(Some actual astronomical info ;)

Christians cannot ascribe to this possibility.

Is not compliant with the Book of Revelation.

Thanks for the links.

[Darksheare]

Heh heh heh.

The “Forge of God” by Gregg Bear was one of the best books on the destruction of the Earth that I have read.

I’m working on a homegrown lopsided supernova drive. If I get it to work, I think it will change the planet forever.

[BenLurkin]

You’re joking?

[Pox]

Anvil of the Stars was an interesting sequel from a Sci-Fi point of view.

[Sawdring]

Yes, that one was pretty good also.

[West Texas Chuck]

I say let ‘em crash.

I am a little nebulous about this, but is that picture giving me the finger????

:-)

[rdl6989]

That would be a bad day at the office for sure.

[grey_whiskers]

Forget the name.

What kind of T-shirt was he wearing?

Did it have comic book chicks bearing guns?

If so, that is UNACCEPTABLE according to feminists.

Because, narrative.
And women in science.
