Destruction Of An Oceans’ Worth Of Water Per Month In The Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami, has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the […]
![The plots of stellar metallicity ([Fe/H]) versus planetary orbital period for all transiting planets from the NASA exoplanet archive. Tranet stands for transiting planet. The transiting planets are split into four groups based on the multiplicity of their systems and are placed on four different panels. The two dotted vertical lines split the metallicity range into three metallicity regions, namely, sub-solar, solar, and super-solar. While low-multiplicity systems are evenly distributed across hosts of all metallicities there is a paucity of high-multiplicity systems around hosts of high metallicity indicating the effect of cold Jupiters on the inner planet multiplicity. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/02/Constraining-Planetary.png?resize=1200%2C717&ssl=1)
