Description
The V1298 Tau system is a young, four-planet system orbiting a ~20 Myr-old star, making it an ideal laboratory for studying the formation and early evolution of planetary systems. However, current estimates of the system’s orbital architecture remain poorly constrained. In particular, planetary eccentricities are largely unconstrained, and mass measurements have large uncertainties. Assuming the current orbital configuration is approximately dynamically stable, we employed a Monte Carlo approach to explore a broad parameter space of planetary masses, eccentricities, and inclinations. Our goal was to identify the most probable values consistent with long-term stability. From this analysis, we find that the outermost planet’s mass is likely near the lower bound of its currently estimated range. Moreover, despite the system likely having passed through a resonance chain during its evolution, the present-day eccentricities of all four planets are expected to be small.
