What to expect from scalar-tensor space geodesy
Hugo Lévy, Joël Bergé, Jean-Philippe Uzan
Scalar-tensor theories with screening mechanisms come with non-linearities that make it difficult to study setups of complex geometry without resorting to numerical simulations. In…
Constraints on chameleon gravity from the measurement of the electrostatic stiffness of the MICROSCOPE mission accelerometers
Martin Pernot-Borràs, Joël Bergé, Philippe Brax +4
This article is dedicated to the use the MICROSCOPE mission's data to test chameleon theory of gravity. We take advantage of the technical sessions aimed to characterize the electr…
MICROSCOPE mission: Statistics and impact of glitches on the test of the weak equivalence principle
Joel Bergé, Quentin Baghi, Alain Robert +6
MICROSCOPE's space test of the weak equivalence principle (WEP) is based on the minute measurement of the difference of accelerations experienced by two test masses as they orbit t…
MICROSCOPE Satellite and its Drag-Free and Attitude Control System
Alain Robert, Valerio Cipolla, Pascal Prieur +14
This paper focus on the description of the design and performance of the MICROSCOPE satellite and its Drag-Free and Attitude Control System (DFACS). The satellite is derived from C…
Effects of a scalar fifth force on the dynamics of a charged particle as a new experimental design to test chameleon theories
Jean-Philippe Uzan, Martin Pernot-Borràs, Joel Bergé
This article describes the dynamics of a charge particle in a electromagnetic field in presence of a scalar fifth force. Focusing to the fifth force that would be induced by a cham…
Fifth force induced by a chameleon field on nested cylinders
Martin Pernot-Borràs, Joel Bergé, Philippe Brax +1
This article investigates the properties of a scalar fifth force that arises in a scalar tensor-theory with a chameleon screening mechanism in the context of gravity space missions…
