Abstract
In this article, we suggest a Sitter model in favor of compact stars in low-mass X-ray binaries. Here, we have considered the presence of a cosmological constant (on a small scale) to investigate the stellar structure. We conclude that this approach is very suitable for the familiar physicalmodel of compact stars in low-mass X-ray binaries. We calculate the probable radius, compactness (u) and surface redshift (Zs) of six compact stars in low-mass X-ray binaries, namely Cyg X-2, V395 Carinae/2S 0921−630, XTE J2123−058, X1822−371 (V691 CrA), 4U 1820−30 and GR Mus (XB 1254−690). We also offer a possible equation of state (EOS) for the stellar objects.
