The Radius Distribution of Small Planets in Binary Star Systems Is Dependent on Stellar Separation
The Astronomical JournalSmall planets ( R _p ≤ 4 R _⊕ ) are divided into rocky super-Earths and gaseous sub-Neptunes separated by a radius gap, but the mechanisms that produce these distinct planet populations remain unclear. Binary stars are the only main-sequence systems with Kendall Sullivan, Adam L. Kraus, Travis A. Berger, Trent J. Dupuy, Elise Evans, Eric Gaidos, Daniel Huber, Michael J. Ireland, Andrew W.

For small planets orbiting within the habitable zones of their host stars, multicolour validation via photometric transit observations offers an efficient alternative to prioritize targets before intensive radial-velocity follow-up, thereby expanding the sample of habitable-zone exoplanets amenable for atmospheric characterisation.Jiang, Chengzi, Selezneva, Aleksandra, Parviainen, Hannu, Murgas, Felipe, Pallé, Enric, Fernández-Rodríguez, Gareb, Geraldía-González, Samuel, Orell-Miquel, Jaume, Narita, Norio, Fukui, Akihiko, de Leon, Jerome, Fukuda, Izuru, Ikuta, Kai, Kawauchi, Kiyoe, Howell, Steve B., Littlefield, Colin, Deveny, Sarah J., Twicken, Joseph D., Schwarz, Richard P., Shporer, Avi +19 moreopenaire +2 more sources
