Result of the MICROSCOPE Weak Equivalence Principle test
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
The space mission MICROSCOPE dedicated to the test of the Equivalence Principle (EP) operated from April 25, 2016 until the deactivation of the satellite on October 16, 2018. In th…
MICROSCOPE mission: final results of the test of the Equivalence Principle
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
The MICROSCOPE mission was designed to test the Weak Equivalence Principle (WEP), stating the equality between the inertial and the gravitational masses, with a precision of $10^{-…
Space test of the Equivalence Principle: first results of the MICROSCOPE mission
Pierre Touboul, Gilles Métris, Manuel Rodrigues +31
The Weak Equivalence Principle (WEP), stating that two bodies of different compositions and/or mass fall at the same rate in a gravitational field (universality of free fall), is a…
Test of the Gravitational Redshift with Galileo Satellites in an Eccentric Orbit
Sven Herrmann, Felix Finke, Martin Lülf +14
On August 22, 2014, the satellites GSAT-0201 and GSAT-0202 of the European GNSS Galileo were unintentionally launched into eccentric orbits. Unexpectedly, this has become a fortuna…
Modeling approaches for precise relativistic orbits: Analytical, Lie-series, and pN approximation
Dennis Philipp, Florian Wöske, Liliane Biskupek +5
Accurate orbit modeling plays a key role in contemporary and future space missions such as GRACE and its successor GRACE-FO, GNSS, and altimetry missions. To fully exploit the tech…
Stability of self-gravitating Bose-Einstein-Condensates
Kris Schroven, Meike List, Claus Lämmerzahl
We study the ground state and the first three radially excited states of a self-gravitating Bose-Einstein- Condensate with respect to the influence of two external parameters, the…
