Radiative 2D models based on Harsono et al. (2013). For all models an envelope with M_env = 1 M_⊙ irradiated by a 1 L_⊙ protostar is assumed, having an outflow cavity with a full opening angle of 30°. The dashed lines indicate the temperature contours for 100, 50 and 20 K. The top and middle panels include a 180 AU and 0.02 M_⊙ disk assuming a 0.1 AU scale height, with centrifugal radius R_c = 200 AU (top) and 50 AU (center) orientated in the horizontal direction. The outflow cavity is oriented in the vertical direction. The bottom panel shows the envelope without a disk.
