摘要：
The atmospheres of many hot white dwarfs contain significant quantities of metals. Various studies have reached different conclusions on the distribution of nitrogen in the atmosphere of REJ1032+532, a 44,350K DA. Here, we examine this object again to gain a better understanding of its nitrogen distribution, and attempt to model the C IV features seen in the DA PG0948+534 (110,0000K).
