ASTROPHYSICS OF WORMHOLES [PDF]

open access: yesInternational Journal of Modern Physics D, 2007
We consider the hypothesis that some active galactic nuclei and other compact astrophysical objects may be current or former entrances to wormholes (WHs). A broad mass spectrum for astrophysical WHs is possible. We consider various new models of the static WHs including WHs maintained mainly by an electromagnetic field.

Cosmological and astrophysical aspects of finite-density QCD [PDF]

open access: yes, 1998
The different phases of QCD at finite temperature and density lead to interesting effects in cosmology and astrophysics. In this work I review some aspects of the cosmological QCD transition and of astrophysics at high baryon density.Comment: 13 pages, 4

Rossby Waves in Astrophysics [PDF]

open access: yesSpace Science Reviews, 2021
AbstractRossby waves are a pervasive feature of the large-scale motions of the Earth’s atmosphere and oceans. These waves (also known as planetary waves and r-modes) also play an important role in the large-scale dynamics of different astrophysical objects such as the solar atmosphere and interior, astrophysical discs, rapidly rotating stars, planetary
