Birmingham Scientists discover extra -solar planets and stars in their latest research. . . . reports Asian Lite News
The astrophysicists from The University of Birmingham have made a startling discovery recently. With the use of the NASA Kepler Space telescope, it has come to their notice that extra-solar planets are losing their atmosphere due to their proximity with extreme hot host stars. This finding as well as further details of their research work has been published in the Nature communications journal.
According to the scientists, the intense radiation exchanged between the extra-solar planets and their host stars is what is causing the envelope of atmosphere to be blown away or stripped off from the planets. They have further discovered that this feature is common in planets with a rocky core and a gaseous outer layer.
Dr Guy Davies, from the University of Birmingham’s School of Physics and Astronomy, said: ‘For these planets it is like standing next to a hairdryer turned up to its hottest setting. There has been much theoretical speculation that such planets might be stripped of their atmospheres. We now have the observational evidence to confirm this, which removes any lingering doubts over the theory.’
Apart from the NASA Kepler Space telescope, the research team has also used asteroseismology to find out more about these planets and stars. They would continue their research and delve further in the future using other advanced technology and satellites like the NASA Tess Mission which is to be launched next year.
