Scientific paper

We have constructed a model of the internal structure of the protoplanetary disk around the forming sun at the stage of collapse of the protosolar nebula with the angular momentum J = 1 - 4 x 10^(52)g cm^2 s^(-1). In calculations of the external heating of the disk we adopt the duration of this stage 10^5 yr resulting from observations. Distributions of the temperature, pressure and other disk parameters are found. Our calculations for the end of the collapse stage showed that magnesium silicates and iron are totally condensed at the radial distance 2 AU and water ice about 20 AU.
