New Chondritic Bodies Identified in Eight Oxygen-bearing White Dwarfs

New Chondritic Bodies Identified in Eight Oxygen-bearing White Dwarfs

We present observations and analyses of eight white dwarf stars (WDs) that have accreted rocky material from their surrounding planetary systems. The spectra of these helium-atmosphere WDs contain detectable optical lines of all four major rock-forming elements (O, Mg, Si, and Fe). This work increas...
