Selection Rules and Channel Structure in a Base Octave Model of Collatz Dynamics
Katharina Lodders
The Collatz iteration is governed by two distinct update rules, depending on the parity of the current iterate: n(i+1)=3n(i)+1 for odd n(i), and n(i+1)=n(i)/2 for even n(i). We sho…
Condensation and the Volatility Trend of the Earth
Katharina Lodders, Bruce Fegley, Klaus Mezger +1
This article describes condensation of the elements and use of condensation temperatures (Tcond) to interpret the volatility trend of the Earth. Major points are: (1) a listing of…
Effects of Metallicity on Graphite, TiC, and SiC Condensation in Carbon Stars
Gabrielle Adams, Katharina Lodders
From transmission electron microscopy and other laboratory studies of presolar grains, the implicit condensation sequence of carbon-bearing condensates in circumstellar envelopes o…
Sulfur in the Giant Planets, their Moons, and Extrasolar Gas Giant Planets
Katharina Lodders, Bruce Fegley
We review sulfur chemistry of the gas giant planets and their moons where sulfur compounds are observed. The major S-bearing gas in the upper atmospheres of the giant planets is H2…
Chemical Equilibrium Calculations for Bulk Silicate Earth Material at High Temperatures
Bruce Fegley, Katharina Lodders, Nathan S. Jacobson
The chemical equilibrium distribution of 69 elements between gas and melt is modeled for bulk silicate Earth (BSE) material from 1000 - 4500 K and 1e-6 to 100 bar. The BSE melt is…
Solar System Abundances and Condensation Temperatures of the Halogens Fluorine, Chlorine, Bromine, and Iodine
Katharina Lodders, Bruce Fegley
We review a large body of literature for concentrations of halogens in chondrites and stellar halogen data used for solar system abundances (i.e., representative abundances of the…
