Abstract: Neutron stars (NSs) are rapidly rotating entities, spinning at approximately 10⁴ Hz, and possess extremely strong magnetic fields, ranging from 10¹³ to 10¹⁴ Gauss. These compact objects, characterized by a radius of about 10 kilometers and a density of 10¹³⁻¹⁴, gcm⁻³ are formed as a result of supernova explosions that mark the end of the life cycle...

Abstract: Studies indicate that short-lived radionuclides (SLRs), including ⁵³Mn, were incorporated into Calcium-Aluminum Rich inclusions (CAIs) in ancient undisturbed primitive meteorites at the time the solar system was forming. In this study, the potential incorporation of ⁵³Mn into CAIs in accordance with the Solar Wind Implantation Model (SWIM) is inves... Show More
