Diversity of exoplanets

This review article delves into the study of low-mass exoplanets: super-Earths, mini-Neptunes and the new categories within and between that we are starting to discover. We provide an overview of current exoplanet observational capabilities, their limitations, and what they are allowing us to learn about low-mass planets.

Hundreds of TESS Exoplanets Might Be Larger than We Thought

The Astrophysical Journal Letters
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from the fraction of starlight blocked when a planet transits its host star.

The Importance of Optical Wavelength Data on Atmospheric Retrievals of Exoplanet Transmission Spectra

The Astronomical Journal
Exoplanet transmission spectra provide rich information about the chemical composition, clouds, and temperature structure of exoplanet atmospheres. Most exoplanet transmission spectra only span infrared wavelengths (≳1 μ m), which can preclude crucial ...
