What is a so called hot Jupiter?
What is a so-called "hot Jupiter"? a planet with a mass similar to Jupiter but very close to the central star and therefore hot. What must be true in order for astronomers to be able to use the Doppler technique to determine a planet's mass? The planet's orbit must be viewed nearly edge on.
What is the likely explanation for the existence of hot Jupiters?
Today, the leading hypothesis for the existence of hot Jupiters is that they formed in their outer solar systems and then migrated inward.
Which of the following is a consequence of the discovery of hot Jupiters for understanding our own solar system quizlet?
Which of the following is a consequence of the discovery of hot Jupiters for understanding our own Solar System? It shows that we do not fully understand the formation of our Solar System. If every star had an Earth-like planet in an Earth-like orbit, how many could be detected by a transit?
How do hot Jupiters occur quizlet?
How do we think hot Jupiters formed? Hot Jupiters formed beyond the frost line, as in our solar system, and migrated inward due to interaction with the solar nebula. Why didn't a hot Jupiter form in our solar system? Because the nebula must have dispersed shortly after the formation of our jovian planets.
Why were so many of the first exoplanets discovered hot Jupiters?
Why were so many of the first exoplanets to be discovered hot Jupiters? Hot Jupiters cause a doppler shift that is easier to detect than that from other planets.
What do we mean by a hot Jupiter quizlet?
What do we mean by a "hot Jupiter"? a planet that is Jupiter-like in size but orbits very close to its star.
Why are hot Jupiters particularly interesting quizlet?
*Hot Jupiters are jovian planets that are very close to their stars. Their discovery came as a surprise to scientists because in our solar system jovian planets are only found far from the Sun.
What process did we have to add to the model to explain hot Jupiter extrasolar planets?
Hot Jupiters like 51 Pegasi b were the first type of planet discovered around sun-like stars. What led to their discovery? It occurred after astronomers started using a technique called the radial velocity method to look for extrasolar planets.
What are hot Jupiters and why was their discovery surprising to astronomers what did their discovery mean for the nebular theory?
*Hot Jupiters are jovian planets that are very close to their stars. Their discovery came as a surprise to scientists because in our solar system jovian planets are only found far from the Sun.
How many exoplanets are hot Jupiters?
They're calling it a “field guide” for hot Jupiters. Of the 4,000+ exoplanets known so far – planets orbiting distant stars in our Milky Way galaxy – several hundred are hot Jupiters. The new guide for scientists combines observations from the Hubble Space Telescope and theoretical models.
How does A hot Jupiter differ from Jupiter quizlet?
How does a hot Jupiter differ from Jupiter? It's much closer to its star. Notice that the planets with the largest radii all fall in the category of "hot Jupiters," which means Jupiter-like planets that are hot because they orbit close to their stars.
Why are hot Jupiter type exoplanets easier to detect than other exoplanet types quizlet?
Why were so many of the first exoplanets to be discovered hot Jupiters? It is a selection effect. Hot Jupiters cause a Doppler shift that is larger and easier to detect than that from other planets.
Why were astronomers surprised to find so many hot Jupiters?
Astronomers were surprised by these "hot Jupiters", because theories of planetary formation had indicated that giant planets should only form at large distances from stars. But eventually more planets of other sorts were found, and it is now clear that hot Jupiters make up the minority of exoplanets.
Why is our Jupiter not a hot Jupiter quizlet?
Why is our Jupiter not a "hot Jupiter"? It is likely that in our system the nebular gas cleared out before it could have much migratory effect on the planet. How much brighter is a Sun-like star than the reflected light from a planet orbiting around it? big planets in edge-on orbits around small stars.
How does a hot Jupiter differ from Jupiter quizlet?
How does a hot Jupiter differ from Jupiter? It's much closer to its star. Notice that the planets with the largest radii all fall in the category of "hot Jupiters," which means Jupiter-like planets that are hot because they orbit close to their stars.
Why is our Jupiter not a hot Jupiter?
Hot Jupiters are heated gas giant planets that are very close to their stars, just a few million miles distant and orbiting their stellar hosts in just a few days. The reason why there isn't one in our Solar System is down to its formation.
