Detection of non - radial g - mode pulsations in the newly discovered PG 1159 star HE 1429 − 1209
We performed time-series photometry of the PG1159-type star HE 1429−1209, which was recently discovered in the ESO SPY survey. We show that the star is a low-amplitude (≈0.05 mag) non-radial g-mode pulsator with a period of 919 s. HE 1429−1209 is among the hottest known post-AGB stars (T eff =160 000 K) and, together with the known pulsator RX J2117.1+3412, it defines empirically the blue edge ...
متن کاملHS 2324 + 3944 : discovery of non - radial pulsations in a hydrogen - rich PG 1159 star ⋆
HS2324+3944 is a peculiar PG1159 star, with a high amount of H in its atmosphere (Dreizler et al. 1995). Its location in the logTeff – log g plane is well inside the GW Vir instability strip. In this paper I report the results of two photoelectric observations of HS 2324+39, which clearly show that the luminosity of this star presents periodical variations with a period of (2140 ± 11) s. This p...
متن کاملABELL 43 , a second pulsating “ hybrid - PG 1159 ” star ⋆
An abstract should be given e report observations of the planetary nebula nucleus Abell 43, obtained at the 2.5m Nordic Optical Telescope, which show that it is a pulsator. Abell 43, a " hybrid-PG 1159 " type star, is the second pulsator of this class, after HS 2324+3944. From the limited data set acquired, we find that Abell 43 exhibits at least two periods of 2600 s and 3035 s, the longest on...
متن کاملThe first PG 1159 close binary system
The archival spectrum of SDSS J212531.92-010745.9 shows not only the typical signature of a PG 1159 star, but also indicates the presence of a companion. With time-series photometry of SDSS J212531.92-010745.9 during 10 nights, spread over one month, with the Tübingen 80 cm and the Göttingen 50 cm telescopes, the binary nature of this object has recently been proven. An orbital period of 6.9 h ...
متن کاملThe Nature of the Driving Mechanism in the Pulsating Hybrid PG 1159 Star Abell 43
We extend our previous pulsational stability analyses of PG 1159 stars by modeling the hybrid PG 1159 type star Abell 43. We show that the standard κ-mechanism due to the ionization of C and O in the envelope of this H-rich PG 1159 star is perfectly able to drive g-mode pulsations. Thus, contrary to a recent suggestion, there is no need to invoke any new or exotic mechanism to explain the pulsa...
