Raman Research Institute ki study: X-ray pulsar Centaurus X-3 accretion disk se matter kheenchta hai, jo high-mass binaries mein durlabh hai
21 October 2026 ki DST release ke anusaar Kinjal Roy ke netritva mein Raman Research Institute (RRI) ke vaigyanikon ne paya ki chamkeela X-ray pulsar Centaurus X-3 accretion disk ke zariye matter kheenchta hai, jo high-mass X-ray binaries mein durlabh hai.
Summary
Department of Science and Technology ke autonomous institute Raman Research Institute (RRI) ke scientists ne paya ki sabse chamkeele X-ray pulsars mein se ek Centaurus X-3 accretion disk ke zariye material accrete karta hai. Researcher Kinjal Roy ke netritva mein team ne chaar secondary emission lines ka adhyayan kiya aur unke badlaav ka kaaran pulsar ke saath ghoomne wali accretion stream ko bataya, jo sirf disk hone par hi sambhav hai. Yeh durlabh hai kyunki high-mass X-ray binaries aam taur par companion star ki stellar wind se seedhe matter lete hain. Lagbhag 24,000 light years door Centaurus X-3 sabse pehle khoje gaye X-ray pulsars mein se ek tha.
