The European Physical Journal C. 81(4): 1-11. doi:10.1140/epjc/s10052-021-09163-z1434-60441434-6052 (Online)https://hdl.handle.net/10321/5413In this paper we study the junction conditions for a generalised matter distribution in a radiating star. The internal matter distribution is a composite distribution consisting of barotropic matter, null dust and a null string fluid in a shear-free spherical spacetime. The external matter distribution is a combination of a radiation field and a null string fluid. We find the boundary condition for the composite matter distribution at the stellar surface which reduces to the familiar Santos result with barotropic matter. Our result is extended to higher dimensions. We also find the boundary condition for the general spherical geometry in the presence of shear and anisotropy for a generalised matter distribution.11 pen0202 Atomic, Molecular, Nuclear, Particle and Plasma Physics0206 Quantum PhysicsNuclear & Particles Physics5101 Astronomical sciences5102 Atomic, molecular and optical physics5107 Particle and high energy physicsArticle2024-08-1410.1140/epjc/s10052-021-09163-z
