A Hot Encounter: The Fiery Fate of WASP-12b

A distant and scorching exoplanet, known as WASP-12b, is hurtling towards its demise in a fiery crash with its parent star, according to new research. Astronomers have long predicted the planet’s ultimate fate, but recent findings have revealed that its demise will happen sooner than previously thought.

WASP-12b, a massive planet twice the size of Jupiter, orbits its star so closely that it completes a year in just one Earth day. This proximity classifies it as an “ultra-hot Jupiter,” subjected to intense radiation which heats its surface to about 4,000 degrees Fahrenheit (2,210 degrees Celsius).

Unlike anything found in our solar system, the immense gravitational forces from the star have distorted WASP-12b’s shape, transforming it into an egg-like structure. The powerful tidal forces also strip material from the planet, forming a disk of matter around its star.

Previously believed to have around 10 million years left, these recent calculations suggest that WASP-12b will collide with its star in a mere 3 million years. This accelerated timeline is relatively short, considering that the star is estimated to be around 3 billion years old.

The research team, led by Pietro Leonardi of the University of Padova, discovered that the planet’s impending fate is a result of a phenomenon known as “tidal dissipation.” They also found indications that the yellow dwarf star is extraordinarily active, with increased sunspots and plasma outbursts.

Interestingly, their analysis revealed evidence suggesting that the star had already transitioned from its main-sequence phase, a critical stage in stellar evolution. However, further investigation concluded that the star is still in its main-sequence phase, posing a new challenge for the team to explain how rapid tidal dissipation can occur in this context.

The impending crash between WASP-12b and its star is expected to cause a temporary increase in brightness, allowing future generations to witness this dramatic event. While we contemplate the future, Leonardi speculates that other ultra-hot Jupiters may also meet a similar fate. Their findings raise questions about the prevalence of tidal decay and planetary collisions across the universe.

In the vastness of cosmic time, WASP-12b’s fiery demise serves as a reminder of the transient nature of celestial bodies and the fascinating dynamics that shape our universe.
