Abstract

We have observed SBS 1150+599A spectroscopically in the UV using HST to derive C/H ∼ 7.6 and N/H ∼ 7.0 for the first time. The central star temperature is now better constrained to ∼130,000K, but still is not well determined. This uncertainty dominates the error in O/H, which has been the subject of debate, yet with these data, SBS 1150+599A has the lowest O/H of any PN. Furthermore, the physics of this object are so extreme that minor differences in atomic modeling impact the composition analysis strongly. We also find that the binary central star, based on photometric and kinematic variations, exhibits CV-like properties with an amplitude of 13% and an orbital period of 3.924 hours.
