室女座GW

PG 1159-035是PG 1159星的原型，之後就是以PG 1159作為這一類恆星的名稱，這顆恆星是在帕洛馬綠色巡天調查紫外線過量的恆星時發現的天體 ，並且像其它的PG 1159星一樣，是中心正在轉變成為行星狀星雲和白矮星的天體High-resolution ultraviolet spectroscopy of PG 1159-035 with HST and FUSE, D. Jahn, T. Rauch, E. Reiff, K. Werner, and J. W. Kruk,  Astronomy and Astrophysics 462, #1 (January 2007), pp. 281–292.。

在1979年發現PG 1159-035的亮度會變化PG1159-035: A new, hot, non-DA pulsating degenerate, J. T. McGraw, S. G. Starrfield, J. Liebert, and R. F. Green, pp. 377–381 in White Dwarfs and Variable Degenerate Stars, IAU Colloquium #53, ed. H. M. van Horn and V. Weidemann, Rochester: University of Rochester Press, 1979.，並且因而在1985年被歸類為變星，標示為室女座GWThe 67th Name-List of Variable Stars, P. N. Kholopov, N. N. Samus, E. V. Kazarovets, and N. B. Perova, Information Bulletin on Variable Stars, #2681, March 8, 1985.。PG 1159型變星可以稱為室女GW型變星 ，或是再分為DOV和PNNV星§1, Detection of non-radial g-mode pulsations in the newly discovered PG 1159 star HE 1429-1209 , T. Nagel and K. Werner, Astronomy and Astrophysics 426 (2004), pp. L45–L48.§1.1, Mapping the Instability Domains of GW Vir Stars in the Effective Temperature-Surface Gravity Diagram , Quirion, P.-O., Fontaine, G., Brassard, P., Astrophysical Journal Supplement Series 171 (2007), pp. 219–248.。PG 1139-035的變化，和其他的室女GW型變星一樣，是由於本身內部的引力波在非徑向方向上的脈動Asteroseismology of white dwarf stars, D. E. Winget, Journal of Physics: Condensed Matter 10, #49 (December 14, 1998), pp. 11247–11261.  DOI 10.1088/0953-8984/10/49/014.。它的光度曲線在1989年3月曾經被Whole Earth Telescope仔細的觀察超過264小時的時段，和在變化的光譜中發現超過100種週期在300至1,000秒的變光模式 Asteroseismology of the DOV star PG 1159-035 with the Whole Earth Telescope, D.
