Cool DZ white dwarfs – I. Identification and spectral analysis

Abstract White dwarfs with metal lines in their spectra act as signposts for post-main-sequence planetary systems. Searching the Sloan Digital Sky Survey (SDSS) Data Release 12, we have identified 231 cool (300 km s−1. The implications of our results on remnant planetary systems are to be discussed...

Zusammenfassung:Abstract White dwarfs with metal lines in their spectra act as signposts for post-main-sequence planetary systems. Searching the Sloan Digital Sky Survey (SDSS) Data Release 12, we have identified 231 cool (300 km s−1. The implications of our results on remnant planetary systems are to be discussed in a separate paper.
