“奇特的变量”DZ Crucis（Nova Cru 2003）有多奇特？
How peculiar is the "peculiar variable" DZ Crucis (Nova Cru 2003)?
摘要：
变星DZ Cru在2003年8月的爆发中被发现时被认为是一颗新星。然而，这一解释后来受到了挑战，当该物体的第一个光谱被报道时。我们目前的近红外光谱的DZ克鲁获得的新技术望远镜在3个场合，开始1.5年后爆发，目的是建立对象的性质。光谱显示H I，O I，[N I]发射线，以及叠加在尘埃连续谱上的He I P Cygni线。这些观测结果表明，“十字星上的奇特变星”是一颗经典新星。
英文摘要：
The variable star DZ Cru was thought to be a nova when it was discovered in eruption in 2003 August. This explanation was later challenged, however, when the first spectra of the object were reported. We present near infrared spectroscopy of DZ Cru obtained at the New Technology Telescope on 3 occasions, starting 1.5 years after outburst, with the aim of establishing the nature of the object. The spectra display H I, O I, [N I] emission lines, together with He I P Cygni lines superposed on a dust continuum. These observations suggest the "peculiar variable in Crux'' is a classical nova.
