Exploring the Ability of HST WFC3 G141 to Uncover Trends in Populations of Exoplanet Atmospheres Through a Homogeneous Transmission Survey of 70 Gaseous Planets
Billy Edwards, Quentin Changeat, Angelos Tsiaras +14
We present the analysis of the atmospheres of 70 gaseous extrasolar planets via transit spectroscopy with Hubble's Wide Field Camera 3 (WFC3). For over half of these, we statistica…
Constraining the origin of giant exoplanets via elemental abundance measurements
Henrik Knierim, Sho Shibata, Ravit Helled
The origin of close-in giant planets is a key open question in planet formation theory. The two leading models are (i) formation at the outer disk followed by migration and (ii) in…
Five key exoplanet questions answered via the analysis of 25 hot Jupiter atmospheres in eclipse
Quentin Changeat, Billy Edwards, Ahmed F. Al-Refaie +11
Population studies of exoplanets are key to unlocking their statistical properties. So far the inferred properties have been mostly limited to planetary, orbital and stellar parame…
Enrichment of Jupiter's atmosphere by late planetesimal bombardment
Sho Shibata, Ravit Helled
Jupiter's atmosphere is enriched with heavy elements by a factor of about 3 compared to proto-solar. The origin of this enrichment and whether it represent the bulk composition of…
The origin of the high metallicity of close-in giant exoplanets II The nature of the sweet spot for accretion
Sho Shibata, Ravit Helled, Masahiro Ikoma
The composition of giant planets reflects their formation history. Planetesimal accretion during the phase of planetary migration could lead to the delivery of heavy elements into…
The origin of the high metallicity of close-in giant exoplanets: Combined effect of the resonant and aerodynamic shepherding
Sho Shibata, Ravit Helled, Masahiro Ikoma
Context.Recent studies suggest that many giant exoplanets are highly enriched with heavy elements compared to their host star andcontain several tens of Earth masses or more of hea…
