The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host
stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet …

We present 2241 exoplanet candidates identified with data from the Transiting Exoplanet
Survey Satellite (TESS) during its 2 yr Prime Mission. We list these candidates in the TESS …

Mass, radius, and age measurements of young (≲ 100 Myr) planets have the power to
shape our understanding of planet formation. However, young stars tend to be extremely …

The extreme ultraviolet (EUV)/X-ray photoevaporation and core-powered mass-loss models
are both capable of reproducing the bimodality in the sizes of small, close-in exoplanets …

Mature super-Earths and sub-Neptunes are predicted to be≃ Jovian radius when younger
than 10 Myr. Thus, we expect to find 5–15 R⊕ planets around young stars even if their older …

The system of two transiting Neptune-sized planets around the bright, young M-dwarf AU
Mic provides a unique opportunity to test models of planet formation, early evolution, and …

Wide-field surveys for transiting planets are well suited to searching diverse stellar
populations, enabling a better understanding of the link between the properties of planets …

All-sky photometric time-series missions have allowed for the monitoring of thousands of
young (t age< 800 Myr) stars in order to understand the evolution of stellar activity. Here, we …

Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits,
and structures are shaped by their environment. Young planets (< 1 Gyr) offer an opportunity …
