SUMMARY

WD 1445+017 b is a planet in close proximity to the white dwarf WD 1445+017, located just 520,000 miles from the star. The discussion highlights the improbability of a typical planet surviving such conditions, particularly during the Red Giant phase of the star, which would have vaporized most celestial bodies. The possibility that WD 1445+017 b could be the remnants of a massive brown dwarf is raised, suggesting a unique evolutionary path for this celestial object. An article detailing the disintegration of a planet orbiting this star can be found at Astronomy Now.

PREREQUISITES
  • Understanding of white dwarf evolution and characteristics
  • Knowledge of planetary formation and destruction in stellar environments
  • Familiarity with brown dwarf properties and classifications
  • Basic astronomy terminology related to stellar lifecycle
NEXT STEPS
  • Research the lifecycle of white dwarfs and their impact on surrounding celestial bodies
  • Investigate the characteristics and formation of brown dwarfs
  • Explore case studies of planets in close orbits around white dwarfs
  • Read the article on the disintegration of planets near white dwarfs for detailed insights
USEFUL FOR

Astronomers, astrophysicists, and students interested in stellar evolution, planetary science, and the dynamics of celestial bodies in extreme environments.

I've just wondered how it is possible for a planet so close to a white dwarf could exist. Yes, the atmosphere of the star during the Red Giant stage would have acted as counterbalance to mass loss, forcing it into a closer orbit. But it would have vaporized any normal planet or gas giant. Let alone, let it last so long, that it only orbits 520,000 miles from the star, or much closer than the star's original radius. Could it be the remains of a massive brown dwarf? Is there any evidence of what the planet could have been? I just want to find out how this scenario could be truly made. Does anyone know anything about the planet? I want to find out more...
