Internal instabilities in magnetized jets
Upasana Das, Mitchell C. Begelman
We carry out an extensive linear stability analysis of magnetized cylindrical jets in a global framework. Foregoing the commonly invoked force-free limit, we focus on the small-sca…
Instability in strongly magnetized accretion discs: A global perspective
Upasana Das, Mitchell C. Begelman, Geoffroy Lesur
We examine the properties of strongly magnetized accretion discs in a global framework, with particular focus on the evolution of magnetohydrodynamic instabilities such as the magn…
A possible evolutionary scenario of highly magnetized super-Chandrasekhar white dwarfs: progenitors of peculiar type Ia supernovae
Upasana Das, Banibrata Mukhopadhyay, A. R. Rao
Several recently discovered peculiar type Ia supernovae seem to demand an altogether new formation theory that might help explain the puzzling dissimilarities between them and the…
