Research description

Characterisation and Analysis of X-ray Binary Systems

X-ray binary systems are a type of binary star system in which one of the stars is a compact object, either a black hole or a neutron star, that accretes matter from its companion star. The accretion process produces intense X-ray emission, making X-ray binaries some of the brightest X-ray sources in the sky. X-ray binaries are important probes of astrophysical processes, such as mass transfer, accretion physics, and the formation and evolution of compact objects, and they have important implications for the study of the larger-scale structure and evolution of the Universe. Following are few open questions in this field, currently I am working:

  1. What is the nature of the accretion process in X-ray binary systems, and how does it vary across different types of systems?
  2. How do X-ray binary systems evolve over time, and what is the role of mass transfer, orbital dynamics, and feedback mechanisms in shaping their evolution?
  3. How do X-ray binary systems produce and emit X-rays, and what are the physical mechanisms that govern the variability and spectral properties of the X-ray emission?
  4. How do X-ray binary systems interact with their surrounding environment, and what are the implications of these interactions for the larger-scale astrophysical phenomena in which they are embedded?
  5. How do X-ray binary systems contribute to the synthesis of heavy elements in the Universe, and what is the role of X-ray binaries in the formation and evolution of galaxies?
  6. What is the role of X-ray binary systems in the production and propagation of high-energy particles, such as cosmic rays and gamma rays?
  7. How can X-ray binary systems be used as probes of fundamental physics, such as the nature of gravity and the properties of compact objects?
  8. What are the limitations and challenges associated with the detection and characterization of X-ray binary systems, and how can these challenges be addressed with new observational techniques and instruments?
  9. How do X-ray binary systems contribute to the understanding of the origin and evolution of black holes and neutron stars, and what are the implications of this for our understanding of the Universe as a whole?
  10. How do X-ray binary systems compare to other types of high-energy astrophysical sources, such as active galactic nuclei and gamma-ray bursts, and what can we learn from the similarities and differences between these sources?
