Summary: | One source of noise for the Laser Interferometer Space Antenna (LISA) will be
time-varying changes of the space environment in the form of solar wind
particles and photon pressure from fluctuating solar irradiance. The
approximate magnitude of these effects can be estimated from the average
properties of the solar wind and the solar irradiance. We use data taken by the
ACE (Advanced Compton Explorer) satellite and the VIRGO (Variability of solar
IRradiance and Gravity Oscillations) instrument on the SOHO satellite over an
entire solar cycle to calculate the forces due to solar wind and photon
pressure irradiance on the LISA spacecraft. We produce a realistic model of the
effects of these environmental noise sources and their variation over the
expected course of the LISA mission. |
