The Chaplygin dark star
O. Bertolami, J. Paramos
We study the general properties of a spherically symmetric body described through the generalized Chaplygin equation of state. We conclude that such object, dubbed generalized Chap…
Fundamental Physics with the Laser Astrometric Test Of Relativity
LATOR Collaboration, S. G. Turyshev, H. Dittus +37
The Laser Astrometric Test Of Relativity (LATOR) is a joint European-U.S. Michelson-Morley-type experiment designed to test the pure tensor metric nature of gravitation - a fundame…
A Mission to Explore the Pioneer Anomaly
The Pioneer Explorer Collaboration, H. Dittus, S. G. Turyshev +37
The Pioneer 10 and 11 spacecraft yielded the most precise navigation in deep space to date. These spacecraft had exceptional acceleration sensitivity. However, analysis of their ra…
Scalar Field Models: From the Pioneer Anomaly to Astrophysical Constraints
J. Paramos
In this work we study how scalar fields may affect solar observables, and use the constraint on the Sun's central temperature to extract bounds on the parameters of relevant models…
The flight of the bumblebee: vacuum solutions of a gravity model with vector-induced spontaneous Lorentz symmetry breaking
O. Bertolami, J. Paramos
We study the vacuum solutions of a gravity model where Lorentz symmetry is spontaneously broken once a vector field acquires a vacuum expectation value. Results are presented for t…
