Two southern planetary nebulae : ESO 263-PN02 and SchuWe-3.
Abstract
Spectroscopic observations show that two newly discovered southern objects, ESO 263 PN-02 and SchuWe-3, are planetary nebulae. ESO 263 PN-02 has a high excitation at the center and the 15m central star is of very early type. SchuWe-3 has ring-shape, is reddened and has a low excitation and electron density in the ring. The distance is estimated between 0.6 and 5 kpc, but is probably closer to the lower value. The measured velocities are +33 + or - 20 and -194 + or - 15 km/s, respectively.
