Abstract: We study properties of the innermost photonsphere in the regular compact star background. We take the traceless energy-momentum tensor and dominant energy conditions. In the regular compact star background, we analytically obtain an upper bound on the radius of the innermost photonsphere as $r_{gamma}^{in}leqslant frac{12}{5}M$, where $r_{gamma}^{in}$ is the radius of the innermost photonsphere and $M$ is the total ADM mass of the asymptotically flat compact star spacetime.
Properties of the Innermost Photon Sphere in a Regular Compact Star Background
In this study, we examine the properties of the innermost photon sphere in a regular compact star background. We specifically analyze the traceless energy-momentum tensor and dominant energy conditions. The regular compact star background refers to the spacetime surrounding a compact star that exhibits regular properties.
One of the key findings of our research is the derivation of an upper bound on the radius of the innermost photon sphere. We analytically obtain this upper bound as $r_{gamma}^{in}leqslant frac{12}{5}M$, where $r_{gamma}^{in}$ represents the radius of the innermost photon sphere and $M$ corresponds to the total ADM mass of the asymptotically flat compact star spacetime. This upper bound offers important insights into the physical characteristics of the innermost photon sphere.
Future Roadmap
Building upon our research, there are several potential avenues for further investigation in the field:
Refining the upper bound: While we have derived an upper bound on the radius of the innermost photon sphere, future research could focus on refining this bound. By considering additional factors or incorporating alternative energy-momentum tensors, we may be able to obtain a more accurate representation of the innermost photon sphere.
Comparative analysis: A comparative analysis of the innermost photon spheres in regular compact star backgrounds and other types of astrophysical objects could provide valuable insights. Understanding the similarities and differences between these systems would contribute to our understanding of the innermost photon sphere and its role in the dynamics of various celestial bodies.
Observational implications: Investigating the observational implications of the innermost photon sphere in regular compact star backgrounds could have significant astrophysical implications. By studying the light rays that pass through or get trapped within the innermost photon sphere, we could gain a deeper understanding of the observable features associated with compact stars and potentially develop new observational techniques.
Extensions to other compact objects: Expanding our study to include other types of compact objects, such as black holes or neutron stars, would broaden our understanding of the innermost photon sphere. Comparing the properties of the innermost photon sphere in different compact objects could provide insights into their unique characteristics and the impact of various factors on the formation and behavior of the photon sphere.
Exploring gravitational effects: Investigating the gravitational effects on the innermost photon sphere in regular compact star backgrounds warrants further exploration. Understanding how the gravitational field affects the innermost photon sphere and its associated properties would allow for a more comprehensive understanding of the interplay between gravity and compact star dynamics.
