NASA Studies New X-ray Binary System

NASA’s Imaging X-ray Polarimetry Explorer (IXPE) has recently investigated the X-ray binary system Swift J1727.8-1613, also known as Swift J1727. This system consists of two stars in orbit, one collapsed into a black hole after exhausting its nuclear fuel.

Formation of Swift J1727

The X-ray binary system formed when one star underwent a supernova explosion. This event led to the collapse of the massive star’s core, creating a black hole. The black hole’s strong gravitational pull attracts material from its companion star.

Accretion Disc and Jets

As the material is drawn towards the black hole, it forms an accretion disc. The intense friction within this disc generates heat, resulting in a glowing corona near the black hole’s edge. Some of the heated material is expelled as powerful jets that travel at nearly the speed of light.

Role of IXPE

The IXPE is a sophisticated instrument designed to study X-rays emitted from space. It allows scientists to observe the behaviour of matter around black holes, despite the black holes being invisible themselves. The data collected by IXPE provides insight into the processes occurring in systems like Swift J1727.

Findings from the IXPE’s study of Swift J1727 have been documented in four separate scientific papers. These papers were published in reputable journals, including The Astrophysical Journal and Astronomy and Astrophysics. The research enhances our understanding of black holes and their surrounding environments.

GKToday Facts for Exams:

1. IXPE is NASA’s Imaging X-ray Polarimetry Explorer. It studies X-rays from space. IXPE helps researchers understand black hole activity and the surrounding matter in detail.
2. Swift J1727 is an X-ray binary system. It consists of two stars. One star collapsed into a black hole after a supernova, creating an accretion disc around it.
3. Accretion Disc is a swirling disc of matter. It forms when material is pulled towards a black hole. Intense friction within generates heat, producing a glowing corona.
