Disk warp simulations viewed on the scale of the protostellar envelope, similar to the field of view shown for L1527 IRS in Fig. 1. These images viewed in 15° increments of azimuthal angle show the effect of a rotating inner disk warp on the scattered light nebula on larger scales. The contour levels are defined as n = 2^m, where m is the set of integers from −2 to 6 and the units are MJy sr⁻¹.
