Towards a complete treatment of the cosmological recombination problem
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/10/18
A new approach to the cosmological recombination problem is presented, which completes our previous analysis on the effects of two-photon processes during the epoch of cosmological hydrogen recombinat...
Magnetars as Highly Magnetized Quark Stars: an analytical treatment
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/10/15
We present an analytical model of a magnetar as a high density magnetized quark bag. The effect of strong magnetic fields (B > 5 x 10^{16} G) in the equation of state is considered. An analytic expres...
Analytical Treatment of the Two-Body Problem with Slowly Varying Mass
Mass loss—binary systems—two-body problem—perturbations.
2009/9/1
The present work is concerned with the two-body problem with varying mass in case of isotropic mass loss from both components of the binary systems. The law of mass variation used gives rise to a pert...

Canonical Treatment of Regular Lagrangians with Holonomic Constraints as Singular Systems
Regular Lagrangians Holonomic Constraints Singular Systems
1999/1/30
Regular Lagrangians with holomonic constraints are treated as singular systems using the canonical method. The Lagrange multipliers are introduced as generalized coordinates. The regular Lagrangians a...
