The wind can have significant molecular content, especially in H2 due to advection – the chemistry is out of equilibrium.https://andrewsellek.com/wp-content/uploads/2025/06/rho_tgas_deltat_20000.pngrho_Tgas_deltaT_20000The density and temperature structure of the wind. Compared to previous models, we find a larger temperature gradient, stabilised by the presence of H2.https://andrewsellek.com/wp-content/uploads/2025/06/mdot_comparison_xray.pngMdot_comparison_XrayMass-loss rates in a photoevaporative wind, comparing a literature model with two on-the-fly thermochemical calcualtions with different X-ray spectra.https://andrewsellek.com/wp-content/uploads/2025/06/profile_evolution.pngprofile_evolutionThe profile of the new mass-loss rate prescriptions across the disc.https://andrewsellek.com/wp-content/uploads/2025/06/2panels_calibrationexample.png2panels_calibrationExampleIf a dust "traffic jam" develops inside the water snowline, the measureable water column densities could be insensitive to the true amount of water.https://andrewsellek.com/wp-content/uploads/2025/06/6panels_scenario1evolution.png6panels_scenario1evolutionThe evolution of the H2O and CO2 in disc models with dust traps.2025-11-09T23:37:20+00:00weekly0.6https://andrewsellek.comdaily1.02025-11-09T23:37:20+00:00
