Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653
L. Naponiello, E. Poretti, K. Rice +24
The architecture of planetary systems hosting ultra-short-period (USP) planets is a key diagnostic for understanding formation and migration scenarios. The presence of outer giant…
Atmospheric Supply of Hydrogen Cyanide Is Not the Rate-limiting Step for Prebiotic Chemistry across Rocky Exoplanets
Gergely Friss, Paul I. Palmer, Marrick Braam +1
Hydrogen cyanide (HCN) is crucial for the RNA World hypothesis, forming biomolecules essential for early life. Life likely emerged around 4 billion years ago during the early Arche…
Constraining Small Planet Compositions for Future Missions
Larissa Palethorpe, Annelies Mortier, Jo Ann Egger +14
Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability. We present a uni…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design
Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44
Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…
