The exoplanet hunt is on. The stakes are high. What will our next-generation telescopes find?
Thousands of transiting exoplanets have been discovered, but for most of these planets we only know their radius and nothing about their mass. With a mass-radius relation, we can infer the masses of all these planets. This paper provides a new, probabilistic mass-radius relation for small planets, and its approach is somewhat unusual…
Although this planet is far from habitable, scientists have confirmed the presence of water vapor in the atmosphere of the WASP-12 system. What does this infer about its planetary atmosphere? Is this in agreement with other studies? The story is not as black and white as we might have thought.
Much of what we know today about exoplanets is due to the success of the radial velocity method. Where does it stand now? What is its future?
Earth’s oceans may have originated mainly from accreted impactors. But do planets in other systems experience the same water delivery mechanism? Or do they even get more water than our world? Find out why you would want to think about this and what the consequences might be.
Hot Jupiters are weird and lonely. Is gravitational perturbation to blame?
