C/O Ratios of Stars with Transiting Hot Jupiter Exoplanets
Johanna K. Teske, Katia Cunha, Verne V. Smith +2
The relative abundances of carbon and oxygen have long been recognized as fundamental diagnostics of stellar chemical evolution. Now, the growing number of exoplanet observations e…
Carbon and Oxygen Abundances in Cool Metal-rich Exoplanet Hosts: A Case Study of the C/O Ratio of 55 Cancri
Johanna K. Teske, Katia Cunha, Simon C. Schuler +2
The super-Earth exoplanet 55 Cnc e, the smallest member of a five-planet system, has recently been observed to transit its host star. The radius estimates from transit observations…
Carbon and Oxygen Abundances in the Hot Jupiter Exoplanet Host Star XO-2N and its Binary Companion
Johanna K. Teske, Simon C. Schuler, Katia Cunha +2
With the aim of connecting the compositions of stars and planets, we present the abundances of carbon and oxygen, as well as iron and nickel, for the transiting exoplanet host star…
