Media: Scientists have found water on distant exoplanets
It is reported that a team of astronomers has identified signs of water on the exoplanet HAT-P-26b. Speculation of researchers, however, only be confirmed or disproved.
On the discovery reported by astronomers working under the guidance of Calvin B. Stevenson (Kevin B. Stevenson). According to researchers, the atmosphere neptunopodobnoy planet HAT-P-26b, which is located in the constellation Virgo, has traces of water vapor, and this may indicate the presence of water there. The conclusions were based on the tool data Low Dispersion Survey Spectrograph 3C (LDSS-3C), located in Chile's Las Campanas Observatory, and in addition, the researchers used data from the Spitzer Space Telescope.
In addition to traces of water in the planet's atmosphere, researchers found a reduced concentration of potassium and also answered questions related to the thesis of the absence / presence of clouds. Scientists have also speculated that the planet's atmosphere has a metallicity near the sun. Research HAT-P-26b will continue as scientists want to know more, including about water.
The very exoplanet was discovered using the so-called transit method, which is a method for detecting extrasolar planets, based on observation of their passage on the background of stars. When the planet is in front of the star, the luminosity of the latter falls. This allows you to define the size of the planet, and in the future this option, as the density. In general, the detection of distant planets associated with a number of difficulties, in particular because of the low luminosity of celestial bodies on the background of the parent stars.
The planet HAT-P-26b is located at a distance from us 437 St. years. The mass of a celestial body can be compared to the mass of Neptune. As is the case with the already mentioned planet, a gas giant in front of us. Approximately half of the weight falls on its core, and the other half is related to the hydrogen-helium atmosphere. One revolution around its star every 4.23 exoplanet makes the day. The star HAT-P-26 is a dwarf orange having a mass and a radius which is equal to 81% and 78% solar respectively. The surface temperature of 5079 K it This star also stands out for its "win over" age, which, according to scientists, is 9 billion years.
Recall recently, another group of researchers announced the discovery of one of the most bizarre planetary systems. This is an enormous planet that is "dancing" with two parent stars. The system found a sun-like star, a dwarf star and a giant planet, clenched between them. Scientists, among other things, they want to get the answer to the question of how all could appear so strange system.
