We present Spitzer MIPS observations at 24 μm of 37 solar-type stars in the Pleiades and combine them with previous observations to obtain a sample of 71 stars. We report that 23 stars, or 32% ± 6.8%, have excesses at 24 μm at least 10% above their photospheric emission. We compare our results with studies of debris disks in other open clusters and with a study of A stars to show that debris disks around solar-type stars at 115 Myr occur at nearly the same rate as around A-type stars. We… Expand

An XMM—Newton observation of the young open cluster NGC 2547: coronal activity at 30 Myr
TLDR
XMM-Newton observations of the young open cluster NGC 2547 demonstrate that the X-ray radiation environment around young solar-type stars remains relatively constant over their first 30 Myr, and show that simple scaling arguments predict higher coronal temperature in coronally saturated stars with lower gravities.
