Effect of spin on the dynamics of multi-component trans-relativistic accretion flows around Kerr black holes
Kalyanbrata Pal, Souvik Ghose, Shilpa Sarkar +1
We investigate the axially symmetric accretion of low angular momentum hydrodynamic matter onto a rotating black hole. The gravitational field under consideration is assumed to be…
Two-temperature accretion flows around strongly magnetized stars and their spectral analysis
Shilpa Sarkar, Kuldeep Singh, Indranil Chattopadhyay +1
We investigate two-temperature accretion flows onto strongly magnetized compact stars. Matter is accreted in the form of an accretion disc upto the disc radius (), where…
Two temperature solutions and emergent spectra from relativistic accretion discs around black holes
Shilpa Sarkar, Indranil Chattopadhyay, Philippe Laurent
An accreting system in two-temperature regime, admits multiple solutions for the same set of constants of motion, producing widely different spectra. Comparing observed spectrum wi…
General relativistic two-temperature accretion solutions for spherical flows around black holes
Shilpa Sarkar, Indranil Chattopadhyay
Matter falling onto black holes is hot, fully ionized and has to be necessarily transonic. Since the electrons are responsible for radiative cooling via processes like synchrotron,…
Transverse oscillations in a coronal loop triggered by a jet
S. Sarkar, V. Pant, A. K. Srivastava +1
We detect and analyse transverse oscillations in a coronal loop, lying at the south east limb of the Sun as seen from the \textit{Atmospheric Imaging Assembly} (AIA) onboard \texti…
