Sakurai's object: a [WC] star in a new bipolar nebula after a VLTP
Griet Van de Steene, Peter van Hoof, Stefan Kimeswenger +5
Optical spectra of the Very Late Thermal Pulse (VLTP) object V4334 Sgr have shown a rapidly changing spectrum resulting from shocks in the outflow, which created a new bipolar nebu…
Non-thermal radio emission in Sakurai's Object
Marcin Hajduk, Peter A. M. van Hoof, Albert A. Zijlstra +5
The very late thermal pulse (VLTP) affects the evolution of 20\% of 1--8\, stars, repeating the last phases of the red giant within a few years and leading t…
The very fast evolution of Sakurai's object
G. C. Van de Steene, P. A. M. van Hoof, S. Kimeswenger +5
V4334 Sgr (a.k.a. Sakurai's object) is the central star of an old planetary nebula that underwent a very late thermal pulse a few years before its discovery in 1996. We have been m…
(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…
The Very Fast Evolution of the VLTP Object V4334 Sgr
P. A. M. van Hoof, S. Kimeswenger, G. C. Van de Steene +3
V4334 Sgr (Sakurai's object) is an enigmatic evolved star that underwent a very late thermal pulse a few years before its discovery in 1996. It ejected a new, hydrogen-deficient ne…
A new Generation of Spectrometer Calibration Techniques based on Optical Frequency Combs
Piet O. Schmidt, Stefan Kimeswenger, Hans Ulrich Kaeufl
Typical astronomical spectrographs have a resolution ranging between a few hundred to 200.000. Deconvolution and correlation techniques are being employed with a significance down…
