11 Many of the recently discovered super-earths most amenable to atmospheric follow-up do not have mass measurements
12 Many of the recently discovered super-earths most amenable to atmospheric follow-up do not have mass measurements ΔD ΔD ~ 2 H R pl / R * Scale height: H = kt μg mg Planetary Mass: Mpl = ktrp 2 μgh
13 Many of the recently discovered super-earths most amenable to atmospheric follow-up do not have mass measurements ΔD ΔD ~ 2 H R pl / R * Scale height: H = kt mg Planetary Mass: Mpl μg = from Teq ktrp 2 μgh from transit 2.3 for gas giants =?? for super-earths from ΔD
14 Many of the recently discovered super-earths most amenable to atmospheric follow-up do not have mass measurements ΔD ΔD ~ 2 H R pl / R * Scale height: H = kt mg Planetary Mass: Mpl μg = from Teq ktrp 2 μgh from transit 2.3 for gas giants =?? for super-earths from ΔD
15 Parameter space study of super-earths with H2-H2O atmospheres T atm = 400 K R pl = 1.5 R log[h2o/h2] = g = 5 25 m/s 2 (Mpl = 1 5 M ) Batalha, Kempton, & Mbarek, ApJL, 2017
16 Parameter space study of super-earths with H2-H2O atmospheres T atm = 400 K Degeneracy region R pl = 1.5 R log[h2o/h2] = g = 5 25 m/s 2 (Mpl = 1 5 M ) Batalha, Kempton, & Mbarek, ApJL, 2017
17 Degenerate spectra as observed with 200 hours of JWST time T obs = 200 hr M4.5 host star (T = 3,000 K, R = 0.2 R ) J = 8 JWST simulations w/ PandExo (Batalha et al. PASP, in press) Batalha, Kempton, & Mbarek, ApJL, 2017

PASP, in press) Batalha, Kempton, & Mbarek, ApJL, 2017
19 The degeneracies are further enhanced by the presence of aerosols Batalha, Kempton, & Mbarek, ApJL, 2017
20 The degeneracies are further enhanced by the presence of aerosols You too can model transmission spectra! Exo-Transmit available publicly on Github Kempton et al., PASP (2017) Batalha, Kempton, & Mbarek, ApJL, 2017
21 Planet formation N-body simulations predict the existence of water-rich super-earths Raymond et al., Icarus, 2006
22 Degeneracies in the mass-radius relationship for low-mass planets provide a challenge to diagnosing bulk water abundances GJ 1214b Lissauer et al., Nature, 2011 (modified c/o E. Lopez)
23 The low bulk density of GJ 1214b informs us of its possible atmospheric composition 1. Mini-Neptune Scenario: Rock / ice interior + hydrogen-dominated atmosphere (mostly H2+ trace H2O, CH4, etc.) 2. Water World Scenario: Mostly H2O - ice interior + steam atmosphere (Rogers & Seager, ApJ, Nettelmann et al. 2011)
24 The low bulk density of GJ 1214b informs us of its possible atmospheric composition 1. Mini-Neptune Scenario: Rock / ice interior + hydrogen-dominated atmosphere (mostly H2+ trace H2O, CH4, etc.) % H2 / He by mass 2. Water World Scenario: Mostly H2O - ice interior + steam atmosphere > 60% H2O by mass (Rogers & Seager, ApJ, Nettelmann et al. 2011)
25 Transit Depth (%) The power of complementary methods: Atmospheric spectroscopy + interior structure modeling Raymond et al., Icarus, Wavelength (microns)
26 Takeaway: 1) Atmospheric studies of small-radius planets should not be undertaken without knowledge of the planet s mass 2) Independent mass measurements (via RVs or TTVs) are necessary in many cases for interpreting the spectra of low-mass exoplanets 3) JWST will provide the first opportunities to unambiguously discover water worlds
