The chemical composition of TS 01, the most oxygen-deficient planetary nebula AGB nucleosynthesis in a metal-poor binary star
Stasinska, G.; Morisset, C.; Tovmassian, G.; Rauch, T.; Richer, M.G.; Pena, M.; Szczerba, R.; Decressin, T.; Charbonnel, C.; Yungelson, L.; Napiwotzki, R.; Simon-Diaz, S.; Jamet, L. (2010)The planetary nebula TS 01 (also called PN G 135.9+55.9 or SBS 1150+599A) with its record-holding low oxygen abundance and its double degenerate close binary core (period 3.9 h) is an exceptional object located in the ... -
A Close Binary Nucleus in the MOST Oxygen-Poor Planetary Nebula PN G135.9 55.9
Tovmassian, G.; Napiwotzki, R.; Richer, M.G.; Stasinska, G.; Fullerton, A.W.; Rauch, T. (2004-11) -
The double-degenerate nucleus of the planetary nebula TS 01: a close binary evolution showcase
Tovmassian, G.; Yungelson, L.; Rauch, T.; Suleimanov, V.; Napiwotzki, R.; Stasinska, G.; Tomsick, J.; Wilms, J.; Morisset, C.; Pena, M.; Richer, M.G. (2010)We present a detailed investigation of SBS 1150+599A, a close binary star hosted by the planetary nebula PN G135.9+55.9 (TS 01). The nebula, located in the Galactic halo, is the most oxygen-poor known to date and is the ... -
The enigma of the oldest nova : the central star and nebula of CK Vul
Hajduk, M.; Zijlstra, A.A.; van Hoof, P.A.M.; Lopez, J.A.; Drew, J.E.; Evans, A.; Eyres, S.P.S.; Gesicki, K.; Greimel, R.; Kerber, F.; Kimeswenger, S.; Richer, M.G. (2007) -
An object that defies stereotypes : X-ray observations of SBS 1150+599A - the binary nucleus of PN G135.9+55.9
Tovmassian, G.; Tomsick, J.; Napiwotzki, R.; Yungelson, L.; Stasinska, G.; Pena, M.; Richer, M.G. (2007)We present X-ray observations of the close binary nucleus of the planetary nebula (PN) PN G135.9+55.9 obtained with the XMM satellite. The nebula is the most oxygen-poor PN known to date and is located in the Galactic halo. ... -
On the Evolved Nature of CK Vul
Hajduk, M.; Zijlstra, A.A.; van Hoof, P.A.M.; Lopez, J.A.; Drew, J.E.; Evans, A.; Eyres, S.P.S.; Gesicki, K.; Greimel, R.; Kerber, F.; Kimeswenger, S.; Richer, M.G. (Astronomical Society of the Pacific, 2008)CK Vul was classified as the oldest observed nova. Recent studies have proven however, that CK Vul cannot be unambiguously classified as any known kind of eruptive variable. We present the optical and radio observations ... -
Recycling Matter in the Universe. X-ray observations of SBS 1150+599A (PN G135.9+55.9)
Tovmassian, G.; Tomsick, J.; Napiwotzki, R.; Yungelson, L.; Pena, M.; Stasinska, G.; Richer, M.G. (American Institute of Physics (AIP), 2008)We present X‐ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM‐Newton satellite. Only one component of the binary can be observed in optical‐UV. New X‐ray observations ...
