We provide estimates of volcanism versus time for planets with Earth-like composition and masses 0.25–25 M ⊕ , as a step toward predicting atmospheric mass on extrasolar rocky planets. Volcanism requires melting of the silicate mantle. We use a thermal evolution model, calibrated against Earth, in combination with standard melting models, to explore the(More)

H + 3 emission is the dominant cooling mechanism in Jupiter's thermosphere and a useful probe of temperature and ion densities. The H + 3 ion is predicted to form in the thermospheres of close-in 'hot Jupiters' where its emission would be a significant factor in the thermal energy budget, affecting temperature and the rate of hydrogen escape from the(More)
The search for habitable planets like Earth around other stars fulfills an ancient imperative to understand our origins and place in the cosmos. The past decade has seen the discovery of hundreds of planets, but nearly all are gas giants like Jupiter and Saturn. Recent advances in instrumentation and new missions are extending searches to planets the size(More)
In agreement with previous work, we show that the presence of the short-lived radionuclide 26 Al in the early Solar System was unlikely (< 2% a priori probability) to be the result of direct introduction of supernova ejecta into the gaseous disk during the Class II stage of protosolar evolution. We also show that Bondi-Hoyle accretion of any contaminated(More)
I propose to carry out a systematic investigation of planet harboring M dwarfs. Specifically, over the course of my thesis I will: i) develop and refine a new high-precision method of sub-millimagnitude " snapshot " photometry to help discover and investigate more transiting planets; ii) apply this method to differential spectroscopy; iii) calibrate(More)
