Dependence of the continuum energy distribution of T Tau stars on thelocation of the temperature minimum. (1981). Revista Mexicana De Astronomía Y Astrofísica, 6(1), 227-229. https://astronomia.unam.mx/journals/rmxaa/article/view/1981rmxaa...6..227c

Abstract

The influence of the position of the temperature minimum on the continuum flux produced by theoretical models of T Tauri stars is investigated. In particular, continuum fluxes for models with similar temperature profiles which differ in the position of the temperature minimum are calculated. Assumed temperature profiles are presented and the transfer and equilibrium equations for a 5-level plus continuum representation for the hydrogen atom is solved using the complete linearization scheme of Auer and Mihalas (1969). This calculation gives the electron density and departure coefficients for the first five levels of the hydrogen atom, which are then used to calculate non-LTE source functions for the continuum produced by these levels. The resulting continuum fluxes are shown and discussed. It is concluded that the discrepancy between theoretical models and observations in the blue and UV regions of the spectrum found in Calvet (1981) cannot be diminished by changing the location of the temperature minimum.
