Contribution

It provides a detailed analysis of defect formation in various brane inflation scenarios, highlighting their properties and implications.

Findings

Cosmic strings are produced at the end of brane inflation.

Different brane inflation models exhibit distinct defect characteristics.

The study connects string theory setups with observable cosmological defects.

Abstract

Brane inflation and the production of topological defects at the end of the inflationary phase are discussed. After a description of the inflationary setup we discuss the properties of the cosmic strings produced at the end of inflation. Specific examples of brane inflation are described: $D-\bar D$ inflation, $D3/D7$ inflation and modular inflation
