Turbulent Convection: Modal Equations and Energy Pathways
S. Sridhar, Nishant K. Singh
We present a framework for studying high Rayleigh number turbulent convection to better understand stellar and planetary convection zones. Utilizing the statistical symmetries of t…
Renewal of Transient Spiral Modes in Disk Galaxies
S. Sridhar
Spiral structure in disk galaxies could arise from transient modes that create conditions conducive for their regeneration; this is the proposal of Sellwood and Carlberg, based on…
Stalling of Globular Cluster Orbits in Dwarf Galaxies
Karamveer Kaur, S. Sridhar
We apply the Tremaine-Weinberg theory of dynamical friction to compute the orbital decay of a globular cluster (GC), on an initially circular orbit inside a cored spherical galaxy…
Generation of large-scale magnetic fields due to fluctuating in shearing systems
Naveen Jingade, Nishant K. Singh, S. Sridhar
We explore the growth of large-scale magnetic fields in a shear flow, due to helicity fluctuations with a finite correlation time, through a study of the Kraichnan-Moffatt model of…
Secular Instabilities of Keplerian Stellar Discs
Karamveer Kaur, Mher Kazandjian, S. Sridhar +1
We present idealized models of a razor-thin, axisymmetric, Keplerian stellar disc around a massive black hole, and study non-axisymmetric secular instabilities in the absence of ei…
Deformation of the Galactic Centre stellar cusp due to the gravity of a growing gas disc
Karamveer Kaur, S. Sridhar
The nuclear star cluster surrounding the massive black hole at the Galactic Centre consists of young and old stars, with most of the stellar mass in an extended, cuspy distribution…
