Data Assimilation for Chemical Reaction Networks and Population Models via a Tunable Observer
Animikh Biswas, Gargi Chaudhuri, Muruhan Rathinam
We consider the problem of state reconstruction for a nonlinear dynamical system from observations of a linear function of the state. We present a design method for a tunable obser…
Can average speed of sound and thermodynamic response functions signal the exotic phases in neutron star cores?
Suman Pal, Gargi Chaudhuri
The speed of sound in dense nuclear matter is crucial for understanding neutron star structure and constraining the EOS. We have discussed in details the decomposition of speed of…
Can a hybrid star with constant sound speed parametrization explain the new NICER mass-radius measurements ?
Suman Pal, Gargi Chaudhuri
We present a reanalysis of NICER observations of PSR J0740+6620 and PSR J0030+0451 to test the consistency of various nuclear equations of state (EoS) within the framework of hybri…
Characterizing the quark-hadron mixed phase in compact star cores : sensitivity to nuclear saturation and quark-model parameters at finite-temperature
Suman Pal, Gargi Chaudhuri
A thorough knowledge of the quark-hadron phase transition in hot and dense matter is essential for constraining the equation of state of neutron stars. In this work, we study the t…
Calculation of the transport coefficients in neutron star
Utsab Gangopadhyaya, Suman Pal, Gargi Chaudhuri
In this work, we have calculated the transport coefficients: shear viscosity and thermal conductivity inside the neutron star core. Our calculation is based on the relativistic kin…
Radial Oscillations and Stability of Neutron Stars with Antikaon Condensates
Manisha Kumari, Sujan Kumar Roy, Soumen Podder +2
Radial oscillations provide a direct probe of the stability and compressibility of neutron stars and are highly sensitive to the equation of state of dense matter. In this work, we…
