  • Fading and variations in the spectrum of the central star of the very young planetary nebula SAO 244567 (Hen 1357). 
    Parthasarathy, M; Garcia-Lario, P; de Martino, D; Pottasch, S. R; Kilkenny, D; Martinez, P; Sahu, K. C; Reddy, B. E; Sewell, B. T (EDP Sciences, 1995-08)
    The optical spectrum of SAO 244567 obtained in 1971 shows that it was a post-AGB B1 or B2 supergiant at that time. It has turned into a planetary nebula (PN ) within the last 20 years. The IUE ultraviolet spectra obtained ...
  • Mode identification and period fitting in six pulsating hot subdwarfs 
    Sahoo, S. K; Baran, A. S; Nemeth, P; Worters, H. L; Pramod Kumar, S; Joshi, S; Kilkenny, D (Cambridge University Press on behalf of Astronomical Society of Australia, 2024-07)
    We report the results of our analysis of six gravity-mode pulsating hot subdwarf stars observed in the short cadence mode by Transiting Exoplanet Survey Satellite. We detected at least 10 pulsation periods in each star, ...
