Planets force their stars to attack with solar flares

A young planet actually makes its stars angry. Astronomers discovered that the hip 67522 B is a gas giant orbit that easily approaches its 17 million-historical host star, triggering a magnetic eruption that bombed the Earth, radiating six times more radiation.

This self-destructive cosmic behavior represents the first confirmed case of planets causing stellar flares through magnetic interactions, and is slowly destroying the planet’s atmosphere in the process.

This discovery published in nature solves decades of mystery about the interaction of magnetic fields from distance stars and reveals dramatic examples of planet suicide by revealing solar weather.

Magnetic tug

The hip joint 67522 B rotates its star every 6.95 days, only 12 star radii, which is enough to disturb the magnetic field line of the star. It can be thought of as the moon that creates tidal forces, and unless it is not pulled on the ocean, the planet drags invisible magnetic lines, extending between the two objects.

The researchers used NASA’s Tess satellite and the European Cheops telescope for five years to track 15 stellar flares and discovered something amazing: 11 of them gathered in the transit phase of the Earth when it saw stars in front of the Earth. Statistical probability of this happening by chance? Less than one thousandth.

“The planet orbits the star away from the 12 star radius, which may be placed in a subalfvénic Cemime,” the researchers explained. In this region, magnetic interference can propagate along the field line toward the surface of the star, triggering the explosive flare at a specific “foot point” location.

The planet’s death spiral

The consequences of hip 67522 B are very serious. The planet experienced a dramatic increase in flare rates during a specific part of its orbit, creating what astronomers call “self-created space weather.” Key findings include:

• 20% of Earth’s orbit’s flare rate is six times higher
• Flare clusters are particularly close to the transit stage (0-0.2 orbital range)
• The total interaction power per second reaches 4.6×10²⁹ERG
• Planets may lose mass at the cosmic time scale

The latest observations from the James Webb Space Telescope show that the atmosphere of the hip joint 67522 B is unusually fluffy. Despite being the size of Jupiter, the Earth weighs only 15 Earth mass and has a density lower than styrofoam polystyrene. New magnetic interaction discoveries may explain this extreme inflation.

Real-time universe violence

The team suspected that the intensity of Earth’s magnetic field determines the intensity of the interaction, although the exoplanet magnetic field has not been reliably measured. Their calculations show that the observed flare power exceeds that simple magnetic reconnection should produce, suggesting that the planet may dig into the star’s own coronal energy.

Each flare can trigger a coronal mass eruption (mass cloud of charged particles) on Earth. In our sunlight, large flares usually trigger these eruptions. For hip 67522b, hit by star-oriented plasma storms may be 50-130% higher atmospheric material than conventional stellar radiation alone.

Bombing can shorten the Earth’s atmosphere for life, from 1 billion years to only 40 billion years. Whether the hip 67522 B can survive as Naruto or shrink into a smaller subneptune depends on this cosmic battle between planetary gravity and stellar anger.

Enter the window to planetary evolution

HIP 67522 represents a prototype for understanding how magnetic star-shaped planetary interactions shape atmospheric evolution in the first few hundred million years of planetary life. The young people of this system make it an ideal laboratory for studying the processes that occur during infancy in our own solar system.

The discovery opens new avenues to detect external star magnetic fields and understand the space weather around other worlds. As astronomers identify more systems, such as HIP 67522, they are building a violent magnetic environment for how a planet survives (or cannot) its host star.

For the hip joint 67522b, ironically it is distinct: allowing it to disturb its very close proximity to the magnetic field of the star also ensures it is the first to bear the brunt. It is a cosmic feedback loop that makes this distant world both the perpetrator and the victim of its own destruction.
