A Geologically Robust Procedure For Observing Rocky Exoplanets to Ensure that Detection of Atmospheric Oxygen is an Earth-Like Biosignature
Carey M. Lisse, Steven J. Desch, Cayman T. Unterborn +7
In the next decades, the astrobiological community will debate whether the first observations of oxygen in an exoplanets atmosphere signifies life, so it is critical to establis…
A procedure for observing rocky exoplanets to maximize the likelihood that atmospheric oxygen will be a biosignature
Steven J. Desch, Stephen Kane, Carey M. Lisse +3
Here we advocate an observational strategy to help prioritize exoplanet observations. It starts with more easily obtained observational data, and ranks exoplanets for more difficul…
Origin of Fe3+ in Fe-containing, Al-free Mantle Silicate Perovskite
Shenzhen Xu, Sang-Heon Shim, Dane Morgan
We have studied the ferrous (Fe2+) and ferric (Fe3+) iron concentrations in Al-free Fe containing Mg-silicate perovskite (Mg-Pv) at pressure (P), temperature (T), and oxygen fugaci…
The Chemical Composition of τ Ceti and Possible Effects on Terrestrial Planets
Michael Pagano, Amanda Truitt, Patrick A. Young +1
τ Ceti (HD10700), a G8 dwarf with solar mass of 0.78, is a close (3.65 pc) sun-like star where 5 possibly terrestrial planet candidates (minimum masses of 2, 3.1, 3.5, 4.3, and 6.7…
