Hot, Young Stars in Giant Gas Cloud Blast Young Planets

A new research has found that the Great Orion Nebula is not only a giant star factory but it also has destroyers of developing planets.

Researchers reached at the conclusion after studying the giant gas cloud located some 1,400 light-years from Earth. It was found by the researchers that the gas cloud contained hot, young stars embedded in the gas cloud that were destructing young planets and blasting the associated debris surrounding nearby baby stars.

The Orion Nebula is known as a birthing ground of stars and some of these stars have the likelihood to turn into planets because of the conditions they are formed under. However, a class of highly luminous stars known as O-type stars has immense potential to end their lives by demolishing all the material required for planet formation.

The new data has showed that these new newborn stars and their forming planets that exist within 0.1 light-years (about 600 billion miles) of 'death stars' have their blanket of dust and gas blown away in just a few million years. As a result, these fast and furious-type stars end the chances of nearby planetary formation because of the stellar explosions.

"O-type stars, which are really monsters compared to our sun, emit tremendous amounts of ultraviolet radiation, and this can play havoc during the development of young planetary systems", said Rita Mann, an astronomer with the National Research Council of Canada in Victoria, British Columbia and lead author. The study was published in the Astrophysical Journal.

For the first time, researchers have found that protoplanetary disks of dozens of embryonic stars with planet-forming potential were vanished because of the intense glow of a neighboring massive star.

The researchers were able conduct the study with help of new high-frequency radio observations obtained through the radio telescopes at the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile.
