TL;DR
This paper evaluates Gaia's potential to detect and measure exoplanets through a large-scale testing campaign, emphasizing its future contributions to exoplanet science.
Contribution
It presents a comprehensive assessment of Gaia's capabilities in exoplanet detection and measurement, contextualizing its scientific impact.
Findings
Gaia can detect a significant number of exoplanets.
Gaia's measurements will improve understanding of planetary system architectures.
The campaign validates Gaia's potential for future exoplanet discoveries.
Abstract
In this paper, we first summarize the results of a large-scale double-blind tests campaign carried out for the realistic estimation of the Gaia potential in detecting and measuring planetary systems. Then, we put the identified capabilities in context by highlighting the unique contribution that the Gaia exoplanet discoveries will be able to bring to the science of extrasolar planets during the next decade.
