(ORDO NEWS) — An international team of astronomers has discovered a previously unknown Jupiter-sized gas giant exoplanet that orbits its star in less than three days.
The discovery was made by the so-called transit search method using data from the Transiting Exoplanet Survey Satellite (TESS) spacecraft. This method allows you to find planets that, rotating around their star, periodically block its light from the observer.
The newly discovered alien world was designated TOI-3235 b. Scientists have already established that the radius of the exoplanet is approximately 1.02 Jupiter radii, and its mass is 0.66 Jupiter masses.
It also has an extremely short orbital period. The new world revolves around its star every 2.59 days and is located at a distance of about 0.027 astronomical units from its star.
The equilibrium temperature on the surface of TOI-3235 b is estimated by researchers at about 330 degrees Celsius.
“Second Jupiter” orbits the parent dwarf star TOI-3235 of spectral type M4. Its age is estimated at about 400 million years.
The radius of this star is about 0.37 of the radius of the Sun, the mass is about 0.39 of the solar mass. Let’s add that the star is located at a distance of about 236 light years from Earth.
The authors of the article also note that TOI-3235 b is a kind of extrasolar world. The fact is that this planet does not fit into the framework of modern models of planetary formation.
In other words, simulations have never previously predicted the existence of such gas giants around such low-mass stars as TOI-3235.
In addition, the new world shows a high light transmission rate, which suggests the presence of an atmosphere on its surface.
