PG 1159-035是PG 1159星的原型，之后就是以PG 1159作为这一类恒星的名称，这颗恒星是在帕洛马绿色巡天调查紫外线过量的恒星时发现的天体 ^[1]，并且像其它的PG 1159星一样，是中心正在转变成为行星状星云和白矮星的天体^[4]。

在1979年发现PG 1159-035的亮度会变化^[5]，并且因而在1985年被归类为变星，标示为室女座GW^[6]。PG 1159型变星可以称为室女GW型变星 ，或是再分为DOV和PNNV星^[7]^[8]。PG 1139-035的变化，和其他的室女GW型变星一样，是由于本身内部的引力波在非径向方向上的脉动^[9]。它的光度曲线在1989年3月曾经被Whole Earth Telescope仔细的观察超过264小时的时段，和在变化的光谱中发现超过100种周期在300至1,000秒的变光模式 ^[10]^[11]。
