New model predicts carbon cycle on exoplanets

The researchers noted that in the search for life on planets outside our solar system, astronomers

There is no way to take pictures to see what's going on there.the spatial resolution required for this; Exoplanets are too small and too far away.However, the planet's atmosphere can reveal a huge amount of information about an object.In this way, scientists can determine what materials are present in the atmospheres of exoplanets.

In search of life, carbon is very interestingto researchers because of the cushioning effect of the carbon cycle on warming and cooling. Thanks to this cycle, the Earth has always maintained a temperature suitable for life, while the Sun has become 20% brighter over the past billions of years.

Scientists have developed a model that linksthe mass of the exoplanet and the size of the core with the amount of CO2 in its atmosphere. Astronomers can now quantify these three factors for an exoplanet with a telescope, and a model will suggest whether a carbon cycle might exist there. The mass and size of the planet's core are additional factors as they strongly influence plate tectonics, which plays a key role in the carbon cycle.

The carbon cycle has a chilling effect onchange in temperature, because as the planet warms, it absorbs more CO2, which leads to a decrease in the greenhouse effect. When it gets colder, the opposite effect occurs. The first step in the cycle is weathering: rocks react with CO2 and rainwater to form bicarbonate (HCO3). It settles to the seabed as sedimentary rock (CaCO3) and a small portion of the carbon is dissolved in the seawater as a residual product. Then plate tectonics transports sedimentary rocks into the Earth's mantle. The volcanoes then release CO2 from the sediment back into the atmosphere.

“We do not know if other planets exist withplate tectonics and the carbon cycle, noted Mark Oosterloo, lead author of the article. - In our solar system, Earth is the only planet where we have discovered a carbon cycle. We hope that the new model can contribute to the discovery of an exoplanet with a carbon cycle, and therefore, possibly, life. "
