Scientists Have Spotted A Giant Exoplanet Orbiting A Dwarf Star
Researchers have spotted a huge gas giant exoplanet orbiting one of the smallest stars with such a possession, HATS-6. It was this star which researchers were actually studying before they were astonished by the presence of the massive exoplanet on the very M-dwarf star, which exists about 500 light years away.
According to The Space Reporter, scientists at the Australian National University chose HATS-6 for study because it was the most convenient object to study or analyze from the whole M-dwarf stars’ herd, as majority of these are small and obscure; the selection of HATS-6 was leveraged by its comparatively cooler temperature.
As the observation began with the university’s Siding Spring Observatory, researchers noticed dim light of the star getting dimmer periodically, this revelation was but of an unknown object completing the orbits and blocking the light while its movements occurred in front of the star.
The astronomers then ventured for a more complete observation; this time with powerful Magellan Telescope in Chile and amateur astronomer T G Tan in Perth, and the preliminary results were corroborated.
The newly discovered exoplanet has similarities with Jupiter and Saturn–with the former more alike in terms of radius and the latter having great similarities of the mass.
What about the origin of the planet? Which sort of atmosphere it has? Nothing known yet. The same nescience has to persist for the event which caused such a huge planet to orbit such a dwarf star. Hypothetically, however, as the researchers have put forth, this could be attributed to a migration, happened early in the history.
The study findings have been detailed in the Astronomical Journal.
