More on the conformal mapping of quasi-local masses: The Hawking-Hayward case
Fayçal Hammad
The conformal transformation of the Hawking-Hayward quasi-local mass is reexamined. It has been found recently that the conformal transformation of the latter exhibits the 'wrong'…
Foliation dependence of black hole apparent horizons in spherical symmetry
Valerio Faraoni, George F. R. Ellis, Javad T. Firouzjaee +2
Numerical studies of gravitational collapse to black holes make use of apparent horizons, which are intrinsically foliation-dependent. We expose the problem and discuss possible so…
Evolution of Cataclysmic Variables and Related Binaries Containing a White-Dwarf
B. Kalomeni, L. Nelson, S. Rappaport +3
We present a binary evolution study of cataclysmic variables (CVs) and related systems with white dwarf accretors, including for example, AM CVn systems, classical novae, supersoft…
Conformal mapping of the Misner-Sharp mass from gravitational collapse
Fayçal Hammad
The conformal transformation of the Misner-Sharp mass is reexamined. It has recently been found that this mass does not transform like usual masses do under conformal mappings of s…
Revisiting the Brans solutions of scalar-tensor gravity
V. Faraoni, F. Hammad, S. D. Belknap-Keet
Motivated by statements in the literature which contradict two general theorems, the static and spherically symmetric Brans solutions of scalar-tensor gravity are analyzed explicit…
Beyond lensing by the cosmological constant
Valerio Faraoni, Marianne Lapierre-Leonard
The long-standing problem of whether the cosmological constant affects directly the deflection of light caused by a gravitational lens is reconsidered. We use a new approach based…
