Called bow shocks, these dramatic arc - shaped features in space are helping researchers to uncover massive, so -
called runaway stars.
They hunted
for runaway stars — objects escaping the cluster at high velocities — that might have been kicked out of orbit by the supernova explosion that formed the magnetar.
Some of the first bow shocks
from runaway stars were identified in the 1980s by David Van Buren of NASA's JPL in Pasadena, Calif..
Lower
velocity runaway stars can be produced when one half of a binary pair explodes as a supernova, blasting its partner away.
Instead of trying to look across, Silva and his colleagues suggest looking up, where hundreds of
runaway stars fly high above the disc of the galaxy.
Recent observations have hinted at the presence of such middleweights, but none of the evidence has been conclusive (
see Runaway stars may solve black hole riddle).
Over the last decade or so, it's become clear that the Becklin - Neugebauer (BN) object is a
rare runaway star, moving away from the centre of the nebula at 30 kilometres per second.
One theory says that
runaway stars start running away when one star of a pair of orbiting stars, known as a binary system, goes supernova and ejects its mate.
And finally, he claims that hot shock waves produced as the star plows through the interstellar gas can been seen in images from NASA's Chandra X-ray Observatory.BN wouldn't be the
first runaway star.
The seven stars are the remains of what likely was once a much larger and massive cluster of many stars, possibly a globular cluster where a middleweight black hole could develop
through runaway star collisions, as indicated by other research.
Thus, due to the low probability of kinematic interaction during their lifetime, they are unable to stray far from the area in which they formed, apart
from runaway stars.
have become
the runaway stars of this little post!
There isn't going to be a discount over the perceptions of one playoff series for
the runaway star player on the Leafs.
Irons is
the runaway star as Tuld.
«The idea is that
the runaway stars act as signal flares, showing the position of the spiral arm, the same way someone lost in the middle of a dense forest could fire one to the sky to show his or her location to an outsider,» says Silva.
But that doesn't stop him fantasising about easier ways: «Wish I had a friend on a planet around
a runaway star in the halo, sending me back a photo.»
If
a runaway star accumulates between 800 and 3000 times the Sun's mass before exploding as a supernova, it can produce a midsize black hole whose mass is 100 to 1000 times the Sun's.
Runaway stars that bulk up by crashing into and merging with one star after another could become the middleweight black holes that have so tantalised astronomers, according to new computer simulations.
What's more,
the runaway star's trajectory got bent by KL's gravity by about 10 degrees.
In 1985, Bolton and his colleague Douglas R. Gies demonstrated that not all «ejected» OB stars (
runaway stars that travel at very high speeds through open space) are the result of the supernova explosion of a companion star.
Rho Leonis is
a runaway star and has a peculiar velocity of 30 km / s at the minimum relative to the nearby stars.
Paying homage to»50s rockabilly style, hairstylist Adir Abergel gave
the Runaways star a modernized pompadour using Fekkai products for the film's premiere.
