This article summarizes a workshop held on March, 2014, on the potential of the James Webb Space Telescope (JWST) to revolutionize our knowledge of the physical properties of exoplanets through transit observations. JWST’s unique combination of high sensitivity and broad wavelength coverage will enable the accurate measurement of transits with high signal-to-noise ratio (S/N). Most importantly, JWST spectroscopy will investigate planetary atmospheres to determine atomic and molecular compositions, to probe vertical and horizontal structure, and to follow dynamical evolution, i.e., exoplanet weather. JWST will sample a diverse population of planets of varying masses and densities in a wide variety of environments characterized by a range of host star masses and metallicities, orbital semi-major axes, and eccentricities. A broad program of exoplanet science could use a substantial fraction of the overall JWST mission.

CHARACTERIZING TRANSITING EXOPLANET ATMOSPHERES WITH JWST (2015, methodology): “Individual integration times were computed from the host star brightnesses (Table 2) and the correlated double sample minimum integration times and bright limits of each instrument mode (c.f. Beichman et al. 2014), including the resulting readout efficiency.”
Equilibrium chemistry down to 100 K (2017, background): “Infrared instruments on board of the James-Webb Space Telescope are expected to revolutionise our understanding of cool objects like exoplanets, brown dwarfs and cool stars (e.g. Marley & Leggett 2009; Beichman et al. 2014).”
SPITZER PHASE CURVE CONSTRAINTS FOR WASP-43b AT 3.6 AND 4.5 μm (2016, background): “The consistency between the results is remarkable, and it bodes well for the JWST science ambitions of the exoplanet atmosphere community (Beichman et al. 2014; Cowan et al. 2015; Stevenson et al. 2016).”
ExoMol line lists – XVIII. The high-temperature spectrum of VO (2016, background): “…et al. 2012; Tennyson & Yurchenko 2016; Tinetti et al. 2011) or more general purpose satellites such as James Webb Space Telescope (JWST) which will also have the capability to study atmospheres of hot Jupiters in 0.6– 28 µm region (Beichman et al. 2014; Wakeford & Sing 2015; Barstow et al. 2015).”
A NEARBY M STAR WITH THREE TRANSITING SUPER-EARTHS DISCOVERED BY K2 (2015, background): “In addition, some of K2’s M-dwarf planets orbit stars bright enough for atmospheric characterization via JWST transmission or emission spectroscopy (Kaltenegger & Traub 2009; Batalha et al. 2013; Beichman et al. 2014).”
starry: Analytic Occultation Light Curves (2018, background): “…the upcoming James Webb Space Telescope (JWST) is expected to dramatically push the boundaries of what can be inferred from these observations, potentially leading to the construction of de facto surface maps of planets in short orbital periods (Beichman et al. 2014; Schlawin et al. 2018).”
Characterization of the K2-18 multi-planetary system with HARPS: A habitable zone super-Earth and discovery of a second, warm super-Earth on a non-coplanar orbit (2017, background): “The measured radius of 2.38 R⊕ is suggestive of an extended H/He envelope (Valencia et al. 2013; Rogers 2015; Fulton et al. 2017) that may contain additional molecular species such as water and/or methane that could be detectable with the James Webb Space Telescope (JWST; Beichman et al. 2014).”
Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets (2016, background): “…Exoplanet Survey Satellite (TESS) will search for these nearby worlds, and a handful of them may be observable with upcoming space-based missions such as the James Webb Space Telescope (JWST) and the WideField Infrared Survey Telescope (WFIRST) (Beichman et al. 2014; Spergel et al. 2015).”
