Journal ArticleDOI
The Element Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars
Klaus Werner,Falk Herwig +1 more
TL;DR: In this article, the observed properties of extremely hot hydrogen-deficient post-AGB stars of spectral type [WC] and PG1159 were reviewed, and the state-of-the-art stellar evolution models which simulate AGB evolution and the occurrence of a late He-shell flash were summarized.
Journal ArticleDOI
The Elemental Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars
Klaus Werner,Falk Herwig +1 more
TL;DR: In this article, the observed properties of extremely hot, hydrogen-deficient post-asymptotic giant branch (AGB) stars of spectral type (WC) and PG1159 were reviewed.
Journal ArticleDOI
Is RX J1856.5-3754 a Quark Star?
Jeremy J. Drake,Herman L. Marshall,Stefan Dreizler,Peter E. Freeman,Antonella Fruscione,Michael Juda,Vinay L. Kashyap,Fabrizio Nicastro,Deron O. Pease,Bradford J. Wargelin,Klaus Werner +10 more
TL;DR: In this paper, Chandra Low Energy Transmission Grating and High Resolution Camera spectroscopic observations of the isolated neutron star candidate RX J1856.5-3754 have been analyzed to search for metallic and resonance cyclotron spectral features and for pulsation behavior.
Journal ArticleDOI
A neutron star stiff equation of state derived from cooling phases of the x-ray burster 4u 1724–307
TL;DR: In this article, an improved method of determining the basic stellar parameters using the data from the cooling phase of photospheric radius expansion (PRE) bursts covering a large range of luminosities was proposed.
Journal ArticleDOI
Is RX J185635-375 a Quark Star?
Jeremy J. Drake,Herman L. Marshall,Stefan Dreizler,Peter E. Freeman,Antonella Fruscione,Michael Juda,Vinay L. Kashyap,Fabrizio Nicastro,Deron O. Pease,Brad Wargelin,Klaus Werner +10 more
TL;DR: In this article, the authors used deep Chandra-HRC-S observations of the isolated neutron star candidate RX J1856.5-3754 to search for metallic and resonance cyclotron spectral features and for pulsation behaviour.
