Chapter 1: Understanding Magnetars

In response to inquiries from our audience, let's delve into the intriguing topic of magnetars. So, what exactly are magnetars, and how do they influence other celestial entities?

A magnetar is a type of neutron star characterized by an extraordinarily strong magnetic field, reaching levels of up to 100 billion Tesla. Currently, scientists have identified 11 such magnetars. These remarkable stars originate from massive stellar bodies with initial masses exceeding 40 solar masses. Upon the death of these stars, they expel their outer layers, leaving behind a dense core known as a neutron star.

Magnetars typically measure about 20 to 30 kilometers in diameter, yet their mass can be multiple times that of the sun. This immense weight is due to the extreme density of neutron stars, where a mere teaspoon of magnetar material can weigh over 100 million tons.

When a massive star loses its outer shell, the remaining core — the magnetar — undergoes rapid rotation, often spinning dozens of times each second. This rapid movement is responsible for its exceptionally strong magnetic field. The lifespan of a magnetar is approximately 10,000 years, during which it emits X-rays and gamma rays. Eventually, its activity diminishes, and it transitions into a standard neutron star.

Magnetars exert gravitational forces on surrounding objects just like ordinary stars do. However, their magnetic fields can accelerate trapped particles to incredibly high speeds, resulting in the production of X-ray radiation. This radiation is so intense that it can incinerate any living organisms in its vicinity, reaching distances of several light-years, although it has minimal effects on inanimate matter.
