Scientists discover pumpkin like stars, very similar to the Halloween models which can be seen everywhere these days, as they analyzed the source of the very luminous space objects seen in the night sky.
The newly found pumpkin like stars were spotted using data mostly gathered from two NASA missions, Kepler and Swift.
Kepler, which is one of the agency’s spacecraft, was released in 2009 and targets the discovery of other stars similar in size and properties with our Earth, which might be orbiting other space bodies.
Amongst the almost 5,000 stars that could possibly come to host humanity in the future, over 2,000 were spotted by the Kepler mission.
The newly found, pumpkin like stars were observed as researchers were looking for possible variable X-ray sources featuring optical counterparts. These are usually especially active galaxies whose center is a black hole, which also drives the aforementioned emissions.
The pumpkin like stars were observed to have a very rapid spinning speed, as they take a medium of just a few days to complete their orbit, which accounts for a very rapid speed in terms of cosmic rates.
The very rapid rotation speed can lead to an amplification on their surface activity, which is very similar to that noted when observing our galaxy’s Sun. As solar flares and sun spots were noticed, their spinning speed could potentially lead them to an overdrive.
Kepler has helped the scientists determine both the rotation speed and the size of these space bodies, and has also revealed evidence which might suggest the existence of an intense magnetic activity.
All of these observations have lead towards the scientists’ belief that the pumpkin like stars will most probably transform into large scale red giant stars.
According to the study’s lead researcher, the Ames Research Center at California’s Steve Howell, the Sun registers quite a low speed when compared to these new space bodies, as it takes almost a month to complete its orbit.
The pumpkin like stars were also noticed to be brighter than our Solar System’s center, as the X-rays quantity produced by them can be even 100 times bigger than the one generated by the Sun.
Amongst the 18 such pumpkin like stars, the largest of them was called KSw 71 and is 10 times bigger than our Sun. The space object has a rotation speed of just 5.5 days and emits 4,000 as many X-rays than the Sun levels registered during its peak periods.
According to Elena Mason, the study’s co-author, the Swift mission telescopes and the Palomar Observatory in California have also turned their eyes towards the new stars.
The data gathered by these telescopes and previous models seem to suggest that the researchers found just a small number of the existing pumpkin like stars, as approximately 160 are thought to be orbiting in the Universe.
