Why are many of the newly detected extrasolar planets called hot Jupiters?
Many newly detected extrasolar planets are called hot Jupiters because they are large, gaseous planets with characteristics similar to Jupiter, but they orbit very close to their host star. This proximity to their star causes them to have high surface temperatures, hence the term "hot."
What planets are large fast moving and made mostly of gases?
The "exoplanets" known as "Hot Jupiters".
What planets are large fast moving and made mostly of gas?
The exoplanets called "Hot Jupiters."
Why are many of the detected extrasolar planets called hot-Jupiters?
Many extrasolar planets are called hot-Jupiters because they are gas giants like Jupiter but much closer to their parent stars, leading to high surface temperatures. Their close proximity to the star results in rapid orbital periods and high levels of irradiation, causing them to be hot compared to Jupiter in our solar system.
How might hot Jupiters have gotten so close to the stars they orbit?
Hot Jupiters may have migrated close to their stars due to interactions with the protoplanetary disk during their formation, gravitational interactions with other planets, or tidal forces from the star.
How is the planet HD 189733b possible?
Planets like HD 189733 b, sometimes called "hot Jupiters" are one of the most common types of planets to be detected, largely because they are the easiest to detect. Such planets likely form at a great distance from their parent stars, but their orbits decay, bringing them extremely close to their stars. Hot Jupiters often slowly lose their atmospheres.
Which planet do most known extrasolarplanets most resemble?
Most known extrasolar planets, particularly those discovered so far, resemble Jupiter in terms of their size and gas giant characteristics. Many of these exoplanets are classified as "Hot Jupiters," which are large, gaseous planets that orbit very close to their host stars, resulting in high temperatures. However, the diversity of exoplanets is vast, with many differing significantly from our solar system's planets, including smaller rocky planets similar to Earth.
Have you found any other planets bigger than Jupiter?
Yes, there are planets known as "hot Jupiters" that are larger than Jupiter in terms of mass and size. These exoplanets are gas giants like Jupiter but orbit much closer to their host star, resulting in higher temperatures and different atmospheric compositions.
What is the best explanation for the location of hot Jupiters?
Hot Jupiters are giant gas planets that orbit very close to their stars. They are believed to have migrated inward from their original formation locations due to interactions with the protoplanetary disk or other planets in the system. This migration process could have been caused by gravitational interactions or tidal forces, leading to their current close proximity to their stars.
How do astronomers explain the orbit of hot jupiters?
Astronomers explain the orbit of hot Jupiters, gas giant exoplanets located close to their stars, through theories of planetary migration. These planets likely formed further from their stars and later migrated inward due to gravitational interactions with the protoplanetary disk or through interactions with other bodies. Tidal forces and the dissipative processes in the disk can also help circularize their orbits. Additionally, some hot Jupiters may have formed in situ through rapid gas accretion in their current locations.
What do models suggest make up the clouds on hot Jupiters?
Models suggest that the clouds on hot Jupiters could be composed of minerals like corundum and silicates, as well as exotic compounds such as titanium oxide and aluminum oxide. These clouds may form due to strong winds, vertical mixing, and high temperatures in the atmospheres of hot Jupiters.
What aspect of gas giants is most reasonable for low temperatures?
Not all gas giant planets have low temperatures (most exoplanets are hot "jupiters"). In our solar system the relatively low temperature are a result of the distance they are from the Sun.
