description Kes 75 Overview
Kes 75 is a supernova remnant in the Milky Way, located in the direction of the constellation Aquila. Its interior contains PSR J1846-0258, a young, energetic neutron star classified as a high-magnetic-field pulsar and observed to produce magnetar-like bursts. The remnant and pulsar are studied together in X-rays because they provide evidence about particle acceleration, neutron-star activity, and the evolution of a recent stellar explosion.
help Kes 75 FAQ
What is Kes 75?
Kes 75 is a young supernova remnant in the Milky Way. It is especially important because it contains the energetic pulsar PSR J1846-0258.
What makes PSR J1846-0258 unusual inside Kes 75?
PSR J1846-0258 is a young neutron star with magnetar-like behavior. Its presence gives astronomers a way to study how ordinary energetic pulsars and magnetars may overlap.
Is Kes 75 a planetary nebula?
No, Kes 75 is the debris field from a supernova explosion, not the shell shed by a dying low-mass star. Its compact object, PSR J1846-0258, is evidence of the much more violent supernova process.
Why do astronomers study Kes 75 in X-rays?
The remnant and PSR J1846-0258 emit strong high-energy radiation, making X-ray observations especially informative. Those observations reveal the interaction between the neutron star and the expanding supernova debris.
