How Does a Protostar Form by Magnetized Gravitational Collapse?

The Astrophysical Journal
Star formation through dynamical magnetized collapse remains an area of active astrophysical research. We carry out a comprehensive exploration on the magnetized gravitational collapse of a nonrotating self-gravitating initially spherically symmetric ...

Imprints of primordial magnetic fields in gravitational collapse during early structure formation

Astronomy & Astrophysics
Context. Primordial magnetic fields (PMFs) generated in the early Universe might have left observable imprints on present-day large-scale structure. However, the spatial scales on which primordial signatures are able to survive the nonlinear processes ...

Discussion on the feasibility of dynamic wormhole formation based on the gravitational collapse of Bose–Einstein condensed dark matter on generalized Vaidya space-time

European Physical Journal C: Particles and Fields
To date, wormholes have not been observed. Dynamic wormholes are difficult to detect due to their transient existence or extremely low spacetime curvature contrast, while static wormholes rely on “exotic matter” that violates the Null Energy Condition ...

Signatures of Electromagnetic and Sound Radiation Produced by Gravitational Waves in Core-collapse Supernovae

The Astrophysical Journal
This paper presents the scenario that gravitational waves, generated in the core collapse of a pre-supernova star, can produce both electromagnetic radiation and sound radiation as gravitational waves propagate outward from the collapsing core. While the
