nLab massive type IIA supergravity

Idea

What is called massive type IIA supergravity or Romans supergravity (due to Romans 86) is a deformation of plain type IIA supergravity in which the B-field acquires a mass-term.

Properties

Lift to string theory

The lift of Romans supergravity to to string theory is known as massive type IIA string theory, where the mass term is identified with the RR-field flux form of degree 0 (or of degree 10 by Hodge duality) which reflects the presence of D8-branes.

Black D8-brane solutions

The mass term makes Romans supergravity have black brane-solutions corresponding to D8-branes

(Bergshoess-de Roo-Green-Papadopoulos-Townsend 96, Chamblin-Perry 97, Janssen-Meessen-Ortin 99)

and to D6-D8-brane bound states (Singh 02a, Singh 02b)
