CSI papers published: Multi-phase, non-isothermal transfer of water

Multi-phase, non-thermal transfer of water in a simple geometry by P. Lidon, CSI member Abe Stroock, and colleagues; email: ads10@cornell.eduIt has long been acknowledged that heat and water transport of in soils and plants are intimately coupled. Pioneering work by Philip and de Vries proposed the physical basis and governing equations to...

CSI papers published: Statistical characterization of hot Jupiter atmospheres

Statistical characterization of hot Jupiter atmospheres using Spitzer's secondary eclipses by E. Garhart, CSI member Nikole Lewis, and colleagues; email: nikole.lewis@cornell.eduWe report 78 secondary eclipse depths for a sample of 36 transiting hot Jupiters observed at 3.6- and 4.5 microns using the Spitzer Space Telescope. Our eclipse results...

CSI papers published: Waves in Saturn's inner C ring

Kronoseismology III: Waves in Saturn's inner C ring by R.G. French, CSI member Phil Nicholson and colleagues; email: nicholso@astro.cornell.eduWe investigate waves driven in Saturn’s rings by planetary normal modes, concentrating on the previously unexplored inner C ring. In this region, the known waves all have exceptionally short wavelengths...

CSI papers published: Low-eccentricity formation of ultra-short period planets

Low-eccentricity formation of ultra-short period planets in multi-planet systems by B. Pu and CSI member Dong Lai; email: dong@astro.cornell.eduRecent studies suggest that ultra-short period planets (USPs), Earth-sized planets with sub-day periods, constitute a statistically distinct sub-sample of Kepler planets: USPs have smaller radii (1−1.4R...

CSI papers published: Microbial communities controlling methane

Microbial communities controlling methane and nutrient cycling in leach field soils by C.P. Fernandez-Baca, CSI member Ruth Richardson, and colleagues; email: rer26@cornell.eduSeptic systems inherently rely on microbial communities in the septictank and leach field to attenuate pollution from household sewage.Operating conditions of septic...
