‘Death Wish Planet’ Found Whipping Its Star Into Violent Eruptions

Jupiter-sized exoplanets which emerge as a proxy for accelerating self-sabotage by instigating tremendous outbursts from their parent stars seem as violations to the conventional structure of planetary systems; astronomers have identified such a diabolic planet, HIP 67522 b. Located within its parent star’s magnetic field, HIP 67522 b’s orbital position subjects it to flare beams which surpass the requisite 100 times more energetic than previously defined. Moreover, these beams are slowly detonating the exoplanet’s atmosphere in a form of gradual self-destruction.

 This prompted researchers from Canada and England to issue conclusive remarks about a star and orbiting planet’s relationship existence being tempered by the will of a single body acting upon the other; this situation evoked the contrary position. In doing so, embracing the dependency the star in question has on the orbiter with the sole speculative assumption humanity has about the lacking presence of free will among celestial bodies. Stating these observations and addressing them in the prominent Nature magazine brought to the public anticipation of the unventured interacting systems, where defying fate might still rule over some celestial worlds.

HIP 67522 b is not your typical gas giant. Unlike our Sun which is 4.5 billion years old, HIP 67522 b’s star is only 17 million years old. This exoplanet stays in a very tight orbit around its star, completing a full revolution in just seven days. HIP 67522 itself is a bit larger and cooler than HIP 67522 but is much younger and more volatile, with a considerably potent magnetic field turning it into a cosmic powerhouse.

What sets this system apart is the fact that the planet is not just a victim of stellar fury. In fact, as it orbits, HIP 67522 b actively participates in its star’s violent energy expenditure by collecting energy and sending it bursting along the star’s magnetic field lines similar to how a surfer pulls on a tow rope. When the bursts reach the star’s surface, they unleash enormous flares around 10,000 times more powerful than our Sun’s typical output.

The Whip-Crack Effect: How a Planet Triggers Stellar Fury

This phenomenon features a distinctive tampographic action literally like ‘cracking a whip’. 

  • The planet interacts magnetically with the star releasing Alfvén waves (magnetic ripples) which travel at high speeds along field lines. 
  • These waves reach the surface of the star where they flare explosive unstable plasmas, destabilizing unstable plasma loops and thus initiating explosive flares. 
  • Importantly, the flares, which aloft tremendous energy, are entirely triggered and synchronized with the planet Transits, displaying causation instead of mere coincidence. 

“The energy of the flares is far more than the waves themselves,” Ilin, lead author from Netherlands Institute for Radio Astronomy explains, “it’s akin to igniting a match near an gas leak the planet is detonating explosives which are already prepared to explode”.

The outcomes for HIP 67522 b slash its beleaguered self as follows:  

  • The HIP 67522 b experiences severe outer radiation six times more than what it would have received, were it to passively orbit.  
  • HIP 67522 b’s ‘cotton candy’ atmosphere compared to Jupiter is less than half dense is being eroded furiously,  
  • At most 100 million years from now, HIP 67522 b could transform from a Jupiter-sized to a Neptune-sized husk.  

As Ilin puts it, We have seen stars evaporate planets before, but have never seen a planet basically self-destruct.

Why Youth Matters: A Recipe for Cosmic Chaos

HIP 67522 is only 17 million years old and its violent phenomena are a consequence of its dynamic interaction with the surrounding environment: 

  • Younger stars are more active and have stronger angular momentum . 
  • In planets with decaying magnetic fields, there is a higher chance of interference from other planetary bodies. 
  • Potentially, this means that during the adolescent phase of stellar development, there could be other similar systems, which suggests that previously, some form of planetary evolution was missed.

Maximilian Günther, project scientist for ESA’s Cheops, explains, “If this is common in young systems, we may have underestimated how many planets die young.”

A New Frontier: Hunting More “Death Wish” Planets

The finding creates an additional subfield of astrophysics:  

  • X-ray and ultraviolet observational follow-ups will determine the lethal efficacy of these flares.  
  • ESA Plato mission (2026) shall search for “smaller” flares in close stellar systems.
  • Given the nature of giant close-orbiting exoplanets, statistical studies could provide an answer if this is a one-of-a-kind event or a universal phase all peri-giant close-orbiters go through.  

“I have a million questions,” Ilin states. “This is the completely new phenomenon, we are just starting to explore.”

Conclusion: A Cosmic Suicide or a Universal Phenomenon?

HIP 67522 b is not merely a celestial curiosity. It is a “living laboratory” for the most extreme forms of star-planet interplay. Its existence raises the possibility of some planets actively designing their own destinies, amassing their stars into a self-destructive feedback loop.

While astronomers continue searching the cosmos for more such systems, one thing is obvious: the universe has a taste for the dramatic and this “death wish planet” is its latest and most violent exhibition.
