Radiation-Driven Origin of Super-Equipartition Magnetic Fields in Accretion Discs and Outflows
Mukesh Kumar Vyas, Asaf Pe'er
Magnetic fields play a central role in accretion physics around black holes, yet their physical origin within accretion flows remains an open problem. In this work, we investigate…

Gas Pressure Driven Screening Forces and Pebble Aggregation: A Pathway for Growth in Planet Formation
Mukesh Kumar Vyas
The formation of planetesimals from cm-sized pebbles in protoplanetary disks faces significant barriers, including fragmentation and radial drift. We identify a previously unaccoun…

Generation of magnetic fields around black hole accretion discs due to non conservative radiation fields
Mukesh Kumar Vyas, Asaf Pe'er
We investigate the generation of magnetic fields above black hole accretion discs due to the non-zero curl of the disc radiation field. By self consistently computing the component…
