The Planetary Ephemeris Program: Capability, Comparison, and Open Source Availability
John F. Chandler, James B. R. Battat, Thomas W. Murphy +3
We describe for the first time in the scientific literature the Planetary Ephemeris Program (PEP), an open-source general-purpose astrometric data analysis program. We discuss, in…
Modeling and Analysis of the APOLLO Lunar Laser Ranging Data
R. D. Reasenberg, J. F. Chandler, N. R. Colmenares +3
The Earth-Moon-Sun system has traditionally provided the best laboratory for testing the strong equivalence principle. For a decade, the Apache Point Observatory Lunar Laser-rangin…
Solar system constraints on the Dvali-Gabadadze-Porrati braneworld theory of gravity
James B. R. Battat, Christopher W. Stubbs, John F. Chandler
A number of proposals have been put forward to account for the observed accelerating expansion of the Universe through modifications of gravity. One specific scenario, Dvali-Gabada…
Testing for Lorentz Violation: Constraints on Standard-Model Extension Parameters via Lunar Laser Ranging
James B. R. Battat, John F. Chandler, Christopher W. Stubbs
We present constraints on violations of Lorentz Invariance based on Lunar Laser Ranging (LLR) data. LLR measures the Earth-Moon separation by timing the round-trip travel of light…
The First Lunar Ranging Constraints on Gravity Sector SME Parameters
James B. R. Battat, John F. Chandler, Christopher Stubbs
We present the first constraints on pure-gravity sector Standard-Model Extension (SME) parameters using Lunar Laser Ranging (LLR). LLR measures the round trip travel time of light…
