WASP-104b - one of the darkest open exoplanets
Scientists turned in their research on a distant planet WASP-104b
to it from the Earth about
466 light-years. Although the planet is quite large, but it is by some coincidence reflects only 3% of the incident surface of the light flux. This is the idea of the dim of the known exoplanet astronomy. The planet is a little warmed up and in the photo it seems a little reddish for this reason. Found this miracle in 2014 using the lens of the Kepler telescope, during the observation of dwarf star WASP-104. The yellow dwarf turned out to have a huge gas giant orbiting its star at a frequency of two days. It turns out that a full rotation around the star the planet makes for two days, it is very close and it is for this reason, it is very hot. If you decide at your leisure to find this wonderful planet and its parent star, it is necessary to look for it in the direction of the Leo constellation, there is far, far away at a distance of 466 light-years it is heated to madness revolves at breakneck speed around a hot star. If the planet is a gas and rotates so close to the surface of its star, then it can be called a "Hot Jupiter". This type of planets poorly reflects the falling visible radiation, and for this reason planet WASP-104b
with first approach proved slightly darkened. Subsequent study showed that the planet absorbs about 60% of all incident radiation from the mother star. But then it would have come from British scientists from University in Newcastle-under-Lyme, and they have proved that the planet emits only 2% comes to her radiation from standing next to star, all goes to heat. It turned out the darkest objects ever open orbiting distant stars. You can imagine that the planet reflects light to the same extent as coal Anthracite. Probably the reason for such active absorption of radiation lies in the chemical composition of the planet. The planet has an atmosphere, which largely consists of potassium and sodium vapors, these two elements mainly affect the radiance of the light spectrum by the planet WASP-104b
. If you are interested in the topic of the planet WASP-104b
, you can read more about it in a special publication of the magazine New Scientist.
The planet is synchronously rotating around the star and it turns out that she is constantly facing the star with one hand, he is very hot, and the rest of the planet is much colder. Everything seems interesting, but what is a little hard to believe that the planet is blacker than coal, something here is clearly not glued and to believe in fables is not yet ready.
