Coolest Star Spotted
posted in Outer Space |
A team of scientists have discovered the coolest star which is about 40-light years away from the Earth. It has been unearthed that this dim-lit, cool and lonely star has a mass between 15-30 times the mass of Jupiter.
The star, which is also being referred to as the “brown dwarf star” , is said to have a surface temperature of 660 degrees Fahrenheit or 350 degrees Celsius, which is equal to the surface temperature of the planet Mercury at the equator and cooler than the surface temperature of Venus.
This brown dwarf star is distinct because it falls right in the middle of the mega-planets and the smaller stars. Usually the stars which fall in this territory are referred to as the “Y class dwarf”.
Loic Albert, stellar researcher from the Canada France Hawaii Telescope, Hawaii is of the opinion that the “CFBDS0059” star, as it has been named, maybe the last visible spectral type of star lying between the planets and the stars.
Albert’s team claims that Y class dwarfs are generally dim in nature and cannot be identified so easily. Forget naked eye, it is difficult to identify the same through a telescope too. This is mainly due to the fact that it is not hot enough to glow red and bright. Instead, the dwarf star glows below the red hot temperature in the infrared light.
The team therefore made use of studying the CFBDS0059 star with the help of near-infrared and infrared instruments of the Canada France Hawaii and the Gemini North telescopes in Hawaii, together with the European Southern Observatory’s NTT telescope in Chile.
