Exoplanet Volatile Carbon Content as a Natural Pathway for Haze Formation [PDF]
Astrophysical Journal Letters, 2023 We explore terrestrial planet formation with a focus on the supply of solid-state organics as the main source of volatile carbon. For the water-poor Earth, the water ice line, or ice sublimation front, within the planet-forming disk has long been a key ...E. Bergin, E. Kempton, M. Hirschmann, S. Bastelberger, D. Teal, G.

Science, 2023 Theories of planet formation predict that low-mass stars should rarely host exoplanets with masses exceeding that of Neptune. We used radial velocity observations to detect a Neptune-mass exoplanet orbiting LHS 3154, a star that is nine times less ...G. Stefansson, S.
