Query: Gravitational field of scalar lumps in higher-derivative gravity   We study the gravitational field sourced by localized scalar fields (lumps)
in higher-derivative theories of gravity. By working in a static and
spherically symmetric configuration, we find the linearized spacetime metrics
generated by scalar lumps for several Lagrangians: the vanishing potential,
i.e. free massive scalar field, a polynomial potential, and the tachyon
potential in open string field theory. We perform the analysis for different
theories of gravity: Einstein's general relativity, four-derivative gravity,
and ghost-free nonlocal gravity. We discuss the limit of validity of our
analysis and comment on possible future applications in the context of
astrophysical compact objects.
