<Sara Seager> develops physical methods for interpreting <exoplanets>. With <Dimitar Sasselov>, she calculated atmospheric transmission during an <exoplanet transit>: absorption in the planetary limb makes the measured transit depth depend on <wavelength>. Their work identified strong atomic features and cloud height as observationally useful diagnostics.<Theoretical Transmission Spectra During Extrasolar Giant Planet Transits by Sara Seager and Dimitar Sasselov>[Abstract: transmission method, predicted absorption and cloud-depth constraint]{ref}
Her models of solid <planets> also connect measured <mass> and <radius> to bulk composition through an <equation of state>. They showed how such measurements can distinguish broad iron-rich, silicate-rich and water-rich families while leaving finer compositional ambiguities. A measured mean <mass density> therefore constrains a family of interior models rather than uniquely revealing an interior.<Mass-radius relationships for solid exoplanets by Sara Seager and others>[Abstract: composition families, equations of state and limits of mass–radius inference]{ref}
