US EditionClingy Planets Can Trigger Their Own Doom, Cheops and TESS Suggest
- Astronomers led by Ekaterina Ilin reported on July 2 in Nature that the exoplanet HIP 67522 b triggers flares on its host star during its seven-day orbit.
- This discovery follows previous theories that close-orbiting planets might disturb stellar magnetic fields, causing eruptions that affect the planet itself.
- Using ESA's Cheops and TESS, the team observed 15 highly energetic flares aligned with the planet's transit, with radiation eroding HIP 67522 b's wispy, Jupiter-sized atmosphere.
- Ilin expressed that many uncertainties remain due to the novelty of this phenomenon, highlighting the importance of studying between 10 and 100 similar star-planet systems to advance theoretical understanding.
- The findings imply HIP 67522 b may shrink to Neptune size within 100 million years, marking the first observed case of a planet affecting its star and facing accelerated atmospheric loss.

Some exoplanets orbit very close to their star, is the case of HIP 67522 b, which is so close that it exerts magnetic influence on its host, which may imply the disappearance of the planet itself. Astronomers of the CHEOPS mission, a space project of the European Space Agency (ESA), have detected that the exoplanet appears to trigger flares of radiation from its star, which, in turn, are destroying the faint atmosphere of the planet and causing …
A Jupiter-size planet as delicate as cotton candy provokes its star
A gas giant planet in distant space has kicked the cosmic hornet's nest: After the world's relentless taunting, its fiery star is after revenge, and the planet will suffer the consequences, astronomers say. Exoplanet HIP 67522 b, fluffed up to the size of Jupiter, circles so close to its star that it’s triggering violent flares — bursts of high-energy radiation — from its host that then blast it in the face. Those flares strip away the planet’s …
'A completely new phenomenon': Astronomers spot a planet causing its star to constantly explode
Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering massive solar flares to erupt. This is the first time a planet has been seen influencing its host star.
Clingy planets can trigger their own doom, Cheops and TESS suggest
Astronomers using the European Space Agency's Cheops mission have caught an exoplanet that seems to be triggering flares of radiation from the star it orbits. These tremendous explosions are blasting away the planet's wispy atmosphere, causing it to shrink every year.
