Most Planets Might Have More than 5 Myr of Time to Form

Abstract The lifetime of protoplanetary disks is a crucial parameter for planet formation research. Observations disk fractions in star clusters imply median lifetimes 1–3 Myr. This very short calls to occur extremely rapidly. We show that young, distant (≤5 Myr, >200 pc) often dominate these types studies. Such frequently suffer from limiting magnitudes leading an over-representation high-mass stars. As stars disperse their earlier, the derived apply best rather than low-mass Including only nearby (<200 minimizes effect magnitude. In this case, with 5–10 thus much longer claimed. timescales provide planets ample time form. How form so faster next grand challenge.
