| Abstract: |
We investigate the eccentricity evolution of non-resonant multiple extrasolar planets during the epoch in which the protostellar disk outside the planets is gradually cleared. We calculate the initial eccentricities of planets around Upsilon Andromeda, HD168443, HD74156, and 47 UMa and analyze their evolution during depletion of the disk. We find that the disk depletion could cause a change in the eccentricities. |
