Constraints on chameleon gravity from the measurement of the electrostatic stiffness of the M I C R O S C O P E mission accelerometers

Bergé, Joel; Pernot-Borràs, Martin; Uzan, Jean-Philippe +4 more

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 electrostatic stiffness of MICROSCOPE's instrument intrinsic to its capacitive measurement system. Any discrepancy between the expected and measured stiffness may result from …
