For instance, there is a planet that was recently discovered. And this is massive planet that orbiting a very tiny star. This planet has no official name as yet, right it is referred to as NGTS-1b. This new planet has roughly the same mass as Jupiter. Amazingly this huge planet is orbiting an old red dwarf that is very dim and only has about half the width of our sun. It is definitely the biggest planet relative to the star it orbits around. It is located so close to its star, that a NGTS-1b year is only 2.6 days on Earth
Massive Planet Defies Current Logic
This is an arrangement that researchers did not expect to uncover. The big reason for the surprise is that recent theories have many times declared that only massive stars grow massive planets, and tiny stars grow tiny planets. This NGTS-1b combination certainly defies that logic.
“Such massive planets were not thought to exist around such small stars,” commented Daniel Bayliss who is from the University of Warwick in a recent posted statement.
Finding the Giant Planet
This planet was observed by the telescopes belonging to Next-Generation Transit Survey who is located in Chile. This planet system is approximately 600 light years away and is probably “very old,” scientists have reported via a study that will appear in a forthcoming issue of Monthly Notices of the Royal Astronomical Society.
Astronomers discovered this giant world by searching for quick blips within starlight that occurs whenever a planet travels across the face of its star. Referred to as transits, these brief dimming events have helped uncover the existence of literally thousands of exoplanets located in the Milky Way galaxy. Many of these have been observed by the Kepler spacecraft of Kepler. However, Kepler did not mention NGTS-1b to anyone.
Of all the worlds that were spotted by Kepler, only a few of them were massive planets in tight orbits. However one of those was indeed reported by John Johnson of Harvard University also has a very large planet that is orbiting a little star. “I wouldn’t call this [new planet] an oddball, in that it wasn’t unexpected,” Johnson stated. “But it certainly is a rarity in our neck of the galaxy, and as such I, as an exoplanetary scientist, find this interesting.”
Researchers are now trying to determine whether those planets were created where they live now, or if they were formed somewhere else and migrated there. And these red dwarf stars, such as the one that this new planet is orbiting around, are extremely hard to study since they are so dim – even though there are lots of them out there to evaluate.
“NGTS-1b was difficult to find, despite being a monster of a planet, because its parent star is small and faint,” quoted Peter Wheatley from the University of Warwick in a recent statement. “Small stars are actually the most common in the universe, so it is possible that there are many of these giant planets waiting to found.”
Up to now, Wheatley and his associates claim that scientists only knew of two similarly huge planets that are orbiting these tiny stars, which are referred to as M dwarf stars, and neither of these two systems has a planet anywhere near as huge as NGTS-1b.
“Hot Jupiters around M dwarfs are super-rare,” stated Lauren Weiss from the Université de Montréal.
