Eccentricity evolution of the four planets in the TOI-700 system over 10,000 years of the integration after 100 Myr of evolution. This plot is a zoom-in of a small range of bottom panel of Figure 2.. Additionally, all planets have low but non-zero eccentricity 0.03 < e < 0.1 over their entire evolution. -- astro-ph.EP
