Astronomers Uncover Volcano-Blanketed Exoplanet 66 Light-Years Away

A team of astronomers, led by UC Riverside's astrophysicist Stephen Kane, has discovered a unique exoplanet, HD 104067.01, located 66 light-years away from our solar system. This rocky planet, similar in size to Earth but with 30% more mass, is covered in active volcanoes, making it resemble Jupiter's moon Io, the most volcanically active body in our solar system.

HD 104067.01, also known as TOI 6713-01, orbits its star every 2.2 days at a distance of 4.57 million kilometers (2.8 million miles). The exoplanet's surface temperature reaches a scorching 4,220°F (2,327°C or 2,600 Kelvin), making it hotter than some low-mass stars. "This is a terrestrial planet that I would describe as Io on steroids," said Stephen Kane. "It's been forced into a situation where it's constantly exploding with volcanoes."

Why this matters: The discovery of this extreme exoplanet expands our understanding of the diverse range of planetary systems that exist beyond our own, potentially revealing new insights into the formation and evolution of planets. This finding also highlights the importance of continued exploration and research into exoplanets, which could ultimately lead to a greater understanding of the possibility of life beyond Earth.

TOI 6713-01 has a highly elliptical orbit, similar to Mercury's in our solar system. The exoplanet is pulled into this unusual orbit by the gravity of its two neighboring planets, a rocky planet and a gas giant. This gravitational interaction causes tidal forces that stretch and twist the planet's molten interior, leading to the intense volcanic activity observed on its surface.

The exoplanet was discovered using NASA's Transiting Exoplanet Survey Satellite (TESS) mission, which searches for exoplanets orbiting the brightest stars. The planet's diameter was determined by calculating the amount of starlight blocked during its transit. Kane and his team are now working on measuring the mass of the planet using HARPS and HIRES instruments, which will reveal its density and the amount of material available for volcanic eruptions.

"This teaches us the extremes of how much energy can be pumped into a terrestrial planet and the consequences of that," said Kane. The discovery of HD 104067.01 brings the total number of confirmed exoplanets to over 5,600, with around 200 being rocky worlds like Earth or Mars. Planetary scientists are particularly interested in finding rocky planets that orbit in their solar system's habitable zone, where liquid water could exist.

The findings, published in The Astronomical Journal, are expected to ignite a new wave of research into exoplanets and the intriguing effects of tidal energy on them. HD 104067.01's unique characteristics make it an ideal candidate for further study, potentially revolutionizing our understanding of the diverse range of planetary systems that exist beyond our own.
