Do hot Jupiter's violate Kepler's laws?
I'm not really sure about this. Let me ask a similar question: Are Keplars Laws consistent with general relativity at the energy level of hot jupiters? Most hot Jupiters lie far inside of Mercurys orbit, which itself does not follow Newtons laws.phyzguy said:No, of course not. Why would you think that they do?
"Hot Jupiters" are a type of exoplanet (planet outside our solar system) that are similar in size and mass to Jupiter, but have extremely high surface temperatures due to their close proximity to their host star. These planets orbit their stars in just a few days, compared to the 12 years it takes for Jupiter to orbit the Sun.
Kepler's laws of planetary motion describe the orbital patterns of planets in our solar system. However, "Hot Jupiters" orbit their host stars in a much closer and faster orbit than any of the planets in our solar system. This violates Kepler's third law, which states that the square of a planet's orbital period is proportional to the cube of its semi-major axis. "Hot Jupiters" have shorter orbital periods and smaller semi-major axes, making them a violation of this law.
Being so close to their host stars, "Hot Jupiters" receive high levels of radiation and heat. This is due to their orbital distance and the type of star they orbit. Additionally, the thick atmospheres of these planets trap in heat, causing their temperatures to rise even further.
Yes, there are other exoplanets that have been discovered that violate Kepler's laws. These include "Hot Neptunes" and "Super Earths", which are smaller planets that also orbit very close to their host stars. However, "Hot Jupiters" were the first type of exoplanet to be discovered and studied, making them the most well-known example of this violation.
There are several theories that attempt to explain the presence of "Hot Jupiters" in other solar systems. One theory is that these planets formed further away from their star and then migrated inward due to interactions with other planets or the protoplanetary disk. Another theory suggests that these planets formed in situ, meaning they formed close to their star and never migrated. However, more research is needed to fully understand the formation and presence of "Hot Jupiters" in other solar systems.
