- Exoplanet HIP 67522 b is losing mass due to its close orbit around its active host star.
- The star's strong magnetic fields and flares are eroding the planet's atmosphere.
- HIP 67522 b is the first observed 'planet with a death wish,' shrinking from Jupiter to Neptune size.
- Astronomers used telescopes like James Webb and CHEOPS to study the star-planet interaction.
- Flares from the star are triggered by the planet's influence, releasing high-energy radiation.
- The planet's atmosphere will erode completely over the next 100 million years.
- Researchers aim to study similar star-planet systems to find other extreme cases.
