The presence of the ocean is one of the conditions necessary for the emergence of life on any планете
However, until recently, the construction of research models, this factor is not taken into account. Normally, researched the weather and atmospheric conditions. In addition, the appearance of its existence is affected by the duration of the day. The two main conditions needed to have life on the exoplanet, explored in detail the staff of the University of East Anglia.
For this they had constructed a complex model as close as possible to the conditions of exoplanets on the basis of which it was found that the speed with which rotates on its axis the planet, affects the ocean. Consequently, it affects the origin of alien life.
The researchers found that the greater the speed, the more cooled the depths of the ocean. However, even in this case remain in the ocean of potential areas suitable for life, where the comfort temperature is maintained. Such areas are located, latitude with a mark of 45 degrees and close to the surface of the ocean. For rapidly rotating planets there is a pattern: at the poles warmer than the equator.
If the speed of the planets rotation slow, it is an effect called "thermohaline circulation". It is formed due to the different densities of water in the ocean induced by the inhomogeneous distribution of ocean salinity and temperature. This phenomenon has on climate is the direct impact.
The conclusion made by scientists, suggests that for planets with a rotation period close to earth, is characterized by fairly uniform distribution at the surface temperature, hence, carbon dioxide in water, and the heat transfer occurs through the poles. The Archean era of the planet's orbital period equal to twelve hours, so, even in the absence of atmospheric oxygen, were the conditions for the emergence of anaerobic organisms.
Experts this model was used not only for celestial bodies, the conditions on which earth-like, but orbiting a yellow dwarf, to which our sun belongs. They plan to combine models of atmospheric and ocean to obtain more accurate data.
It turns out that zones of potentially habitable, not so much. That might relate to her Mars has no ocean, so the fluctuations in temperature there reached a hundred degrees. Can we hope that life on this planet possible?
