Does anyone know of a reference (or website) where I can find the Ricci tensor/scalar for a static, circularly symmetric spacetime (2 + 1) ?
Thanks:)

A circularly symmetric star is a theoretical concept in astrophysics that describes a star with a perfectly symmetrical shape, meaning that all points on its surface are equidistant from its center. This is different from most stars, which have irregular shapes due to their rotation, magnetic fields, and other factors.
A circularly symmetric star is not a natural occurrence and does not form in the same way as other stars. It is a theoretical construct used to simplify calculations and models in astrophysics.
A circularly symmetric star is often described as having a perfect spherical shape, with a uniform temperature and density throughout its entire structure. It may also have a perfectly symmetrical luminosity, meaning that it emits the same amount of light in all directions.
No, it is highly unlikely for a real star to have perfect circular symmetry. Due to various factors such as rotation, magnetic fields, and internal processes, most stars have irregular shapes and variations in their properties.
The study of circularly symmetric stars is important in astrophysics as it helps scientists develop simplified models and calculations for more complex objects, such as stars with irregular shapes. It also allows for a better understanding of how different factors can affect the overall structure and properties of stars.
