2 A realistic evaluation of the systematic bias due to the even zonal harmonics of the geopotential
After the recent approval by the Italian Space Agency (ASI) of the LARES mission, which will be launched at the end of 2008 by a VEGA rocket to measure the general relativistic gravitomagnetic Lense-Thirring by combining LARES data with those of the existing LAGEOS and LAGEOS II satellites, it is of the utmost importance to assess if the claimed accuracy . 1% will be realistically obtainable. T...
متن کاملOn the impact of the secular rates of the even zonal harmonics on the measurement of the Lense-Thirring effect: a quantitative analysis
In this paper we discuss the role of the uncertainty in the even zonal harmonic coefficients Jl of the Newtonian component of the terrestrial gravitational potential from the most recent CHAMP and/or GRACE based Earth gravity models on the measurement of the general relativistic gravitomagnetic Lense-Thirring effect with the nodes Ω of the existing laser-ranged LAGEOS and LAGEOS II satellites. ...
متن کاملSome comments on a recent paper on the impact of the secular variations of the even zonal harmonics on the Lense-Thirring tests with the LAGEOS satellites
In this paper we critically discuss the recent paper gr-qc/0412001 by Ciufolini about the impact of the secular variations J̇l of the even zonal harmonic coefficients of the Newtonian multipolar expansion of the terrestrial gravitational field on the performed tests aimed at the detection of the post-Newtonian gravitomagnetic Lense-Thirring effect in the gravitational field of the Earth with the...
متن کاملQuasi-phase-matching of only even-order high harmonics.
High harmonic spectrum of a quasi-monochromatic pump that interacts with isotropic media consists of only odd-order harmonics. Addition of a secondary pump, e.g. a static field or the second harmonic of the primary pump, can results with generation of both odd and even harmonics of the primary pump. We propose a method for quasi-phase matching of only the even-order harmonics of the primary pum...
متن کاملBounding the mass of the graviton with gravitational waves: Effect of higher harmonics in gravitational waveform templates
Observations by laser interferometric detectors of gravitational waves from inspiraling compact binary systems can be used to search for a dependence of the waves’ propagation speed on wavelength, and thereby to bound the mass or Compton wavelength of a putative graviton. We study the effect of including higher harmonics, as well as their post-Newtonian amplitude corrections, in the template gr...
