Title: Characterizing the Atmosphere of the Lowest-mass Directly Imaged Planet 51 Eri b
Abstract: With deep Subaru/IRCS imaging, we propose to obtain M'-band photometry of the young, low mass exoplanet, 51 Eri b, recently discovered as part of the Gemini Planet Imager Exoplanet Survey. The new exoplanet has a unique combination of a clear methane absorption feature in J and H-band coupled with a young age (< 40 Myr) and close orbit (~13 AU). Furthermore, models suggest that it is 2 Mjup, making it the lowest mass directly imaged planet detected to date. The longer wavelength M'-band flux is highly sensitive to the effective temperature and atmospheric chemistry and is needed to estimate the bolometric luminosity. Determining the properties of this unique exoplanet is important for comparison with both atmosphere and evolution models.
