Birth of a Forbidden Planet: Rising from the Ashes of a Star

Astronomers have discovered a "forbidden planet" called Halla, which is orbiting a dying star. Halla's star has already consumed its available hydrogen and is currently fusing helium. The planet's existence is puzzling because it should have been swallowed when the star expanded in the past. Possible explanations include Halla orbiting a binary star system that merged into a single star, or Halla being a second-generation planet formed from the debris of a stellar collision. The discovery highlights the strange and unpredictable nature of the universe.

Astronomers Discover Forbidden Planet That Defied Death

Astronomers have discovered a "forbidden planet" called Halla, which has survived orbiting a red giant star named Baekdu at a distance of 46 million miles, indicating that some planets can survive the death throes of stars. The giant exoplanet, 1.7 times the mass of Jupiter, should have been destroyed, but its existence challenges previous assumptions about the survival of planets in close orbits around red giants. Possible explanations for Halla's survival include a change in Baekdu's evolution due to a merger with a white dwarf binary partner or the formation of the planet from material pulled out from the dying star by a binary companion. The discovery suggests that planet formation may be more resilient than previously thought.

Surviving the Unthinkable: The Forbidden Planet's Miraculous Escape

The giant planet Halla has defied the odds by surviving the engulfment of its dying star, Baekdu. Scientists propose that Baekdu may have formed from the merger of two stars, preventing it from growing large enough to swallow Halla. Alternatively, Halla could be a newborn planet that formed from the debris of the stellar merger. However, Halla's survival is temporary, as Baekdu is expected to expand again in the future. This discovery suggests the existence of other death-defying planets in the galaxy and calls for further research on star-planet interactions and stellar mergers.
