Abstract
In this work, some aspects of the ambitwistor pure spinor string are investigated. The ghost is presented and its main properties are derived in a simple way, very similar to the usual pure spinor ghost construction. The heterotic case is also addressed with a new proposal for the BRST charge. The BRST cohomology is shown to correctly describe the heterotic supergravity spectrum and a semi-composite ghost is constructed.
