Discovery of Volatile Gas in the Giant Impact Disk Around the 150 Myr Old HD 23514

Discovery of Volatile Gas in the Giant Impact Disk Around the 150 Myr Old HD 23514

We report the discovery of CO _2 gas emission around HD 23514, an F5V star in the ∼150 Myr old Pleiades cluster, hosting one of the rare giant-impact disks with unique mineralogy dominated by silica dust. We show that the dust feature remains stable over several decades, and that the submicron grain...
