NEWSLINE PAPER,-
A team of researchers led by researchers at the University of California Riverside has launched a new member of the star system, HD 104067. Located about 66 light-years from Earth, HD104067 is one of the hottest solar systems.
The newly identified fire planet, named TOI-6713.01, shows extremely extreme conditions so that its surface temperature exceeds the heat of a few stars.
The investigation was conducted using data from NASA's Transiting Exoplanet Survey Satellite (TESS). The researchers initially sought to learn more about the giant planet previously discovered in the system.
However, it was the detection of TOI-6713.01 that drew researchers' attention because the planet showed an environment dominated by volcanic activity and extraordinary heat.
Warmer than a star
TOI-6713.01 is a rocky planet about 30 percent larger than Earth, found to have a surface temperature of 2.326 degrees Celsius.
It's not as hot as the Sun, but it's hotter than some of the stars that have ever been discovered. For comparison, the temperature on Venus, the hottest planet in the solar system, is 471 degrees Celsius.
The pressure makes the planet hot.
The extreme conditions on the planet TOI-6713.01, mainly caused by the warming of the recession, a process involving the gravitational force of the neighbouring planet causing internal friction, thus resulting in significant volcanic activity.
On Earth, the retreat is largely caused by the gravity of the Moon dragging the ocean. However, on satellites like Europa, which freezes on the surface, high pressures create enough heat to melt the ice and produce ocean liquid water under the frozen surface.
The eccentric orbits of these newly discovered planets -- constricted and distorted by the gravitational attraction of two larger outer planets - reflect the dynamics affecting the moon of Jupiter, Io.
This discovery not only highlights the significant impact of gravitational interactions on planetary conditions, but also challenges astronomers' understanding of planetary dynamics.
Researchers say that the effects of the recession on planets have historically not been the main focus of extrasolar planetary research, however, it may change after this discovery.
In the future, the team plans to further investigate TOI-6713.01 by measuring its mass and density, which could provide a deeper insight into the volcanic processes that are taking place.
This ongoing study is expected to explain the role of the retreat effect in extrasuric planetary research, an aspect of the discovery that has largely not been explored.
