A Toy Model for Low Energy Nuclear Fusion
Kaanapuli Ramkumar, Harishyam Kumar, Pankaj Jain
We study the fusion of a proton with a nucleus with the emission of two photons at low incident energy of the order of eV or smaller. We use a step model for the repulsive potentia…
Investigating the Hubble Tension: Effect of Cepheid Calibration
Rahul Kumar Thakur, Harish Kumar, Shashikant Gupta +2
Recent observations of Type Ia supernovae (SNe) by SH0ES collaboration (R11 and R16) diverge from the value reported by recent CMBR observations utilising the Planck satellite and…
Accreting White Dwarfs: Effect of WD Composition on Helium Ignition During Slow Accretion
Harish Kumar, Abhinav Gupta, Siddharth Savyasachi Malu +1
Understanding the explosion mechanism of type Ia supernova is among the most challenging issues in astrophysics. Accretion of matter on a carbon-oxygen white dwarf from a companion…
Slow Accretion of Helium Rich Matter onto C-O White Dwarf: Does Composition of WD Matter?
Harish Kumar, Abhinav Gupta, Siddharth Savyasachi Malu +1
In binary systems, the helium accretion onto carbon-oxygen (CO) white dwarfs (WDs) plays a vital role in many astrophysical scenarios, especially in supernovae type Ia. Moreover, i…
Structure, magnetism and electronic properties in 3-5 based double perovskite (SrCa)FeIrO (0 1): A combined experimental and theoretical investigation
K. C. Kharkwal, Roumita Roy, Harish Kumar +6
The 3-5 based double perovskites offer an ideal playground to study the interplay between electron correlation () and spin-orbit coupling (SOC) effect, showing exotic phys…
Entropy stable discontinuous Galerkin methods for ten-moment Gaussian closure equations
Biswarup Biswas, Harish Kumar, Anshu Yadav
In this article, we propose high order discontinuous Galerkin entropy stable schemes for ten-moment Gaussian closure equations, which is based on the suitable quadrature rules (see…
