TLDR
The theory of polytropic gas spheres in conjunction with the equation of state of arelativislically degenerate electrongas leads to a unique value for the mass of a star built on this model.Abstract:
The theory of thepolytropic gas spheres in conjunction with the equation of state of arelativislically degenerate electrongas leads to aunique value for the mass of a star built on this model. This mass (=0.9I⊙) is interpreted as representing the upper limit to the mass of an ideal white dwarf.read more

Beyond the Cosmological Standard Model
TL;DR: A review of the current state of the field and a framework for anticipating developments in the next decade can be found in this paper, where the authors identify the guiding principles for rigorous and consistent modifications of the standard model, and discuss the prospects for empirical tests.

Quantum-Spacetime Phenomenology
TL;DR: This work reviews the current status of phenomenological programs inspired by quantum-spacetime research and stresses the significance of results establishing that certain data analyses provide sensitivity to effects introduced genuinely at the Planck scale.

TL;DR: It is shown that the high-redshift supernova SNLS-03D3bb has an exceptionally high luminosity and low kinetic energy that both imply a super-Chandrasekhar-mass progenitor, which may provide an explanation for the observed trend that overluminous type Ia supernovae occur only in ‘young’ environments.

Stationary Black Holes: Uniqueness and Beyond
TL;DR: Developments in the subject are reviewed and the uniqueness theorem for the Einstein-Maxwell system is discussed in light of the high degree of symmetry displayed by vacuum and electro-vacuum black-hole spacetimes ceases to exist in self-gravitating non-linear field theories.
