News: Scientists found that Centaurus X-3 draws material through an accretion disk, a rare process in high-mass X-ray binaries.
About Centaurus X-3
- Centaurus X-3 is one of the brightest X-ray pulsars.
- It is also one of the most widely studied binary pulsars.
- Type: It is a high-mass X-ray binary (HMXB) with a companion star more than 10 times the Sun’s mass.
- Location: It lies about 24,000 light-years from earth, in the constellation Centaurus.
- Key Features of Centaurus X-3
- Binary System: It contains a highly magnetized neutron star and an O-star companion.
- The pulsar rotates once every 4.84 seconds and completes an orbit in 2.087 days.
- It gathers material through a disk, an unusual process in high-mass X-ray binaries, where stellar wind capture is more common.
- A stream transfers matter from the disk towards the pulsar, which guides it towards its magnetic poles.
- Secondary radiation occurs when surrounding structures absorb and re-emit radiation from the pulsar.
- Studying this radiation helps scientists understand the system’s physical properties, such as its orientation and magneticfield strength, and improve models of binary pulsars.
About Pulsars
- Pulsars are rapidly spinning, highly magnetized neutron stars.
- Formation: They form when massive stars collapse and explode as supernovae, leaving behind dense cores.
- Radiations: They release radiation from their magnetic poles, creating powerful beams of light.
- Regular Pulses: Their radiation reaches observers at regular intervals, ranging from milliseconds to seconds.
- Observation: Scientists have mainly observed pulsars at radio wavelengths.
