Accreting White Dwarfs among the Planetary Nebulae Most Luminous in [O III]5007 Emission
Noam Soker
I propose that some of the most luminous planetary nebulae (PNs) are actually proto-PNs, where a companion white dwarf (WD) accretes mass at a relatively high rate from the post-as…
Accretion onto the Companion of Eta Carinae During the Spectroscopic Event: II. X-Ray Emission Cycle
Muhammad Akashi, Noam Soker, Ehud Behar
We calculate the X-ray luminosity and light curve for the stellar binary system Eta Carinae for the entire orbital period of 5.54 years. By using a new approach we find, as suggest…
Can we ignore magnetic fields in studies of PN formation, shaping and interaction with the ISM?
Noam Soker
Yes. (As this paper summarizes my talk at the Planetary Nebulae As Astronomical Tools meeting [Gdansk, June 2005], I stay as close as possible to the presentation I gave at the Gda…
X-ray Imaging of Planetary Nebulae with Wolf-Rayet-type Central Stars: Detection of the Hot Bubble in NGC 40
Rodolfo Montez, Joel H. Kastner, Orsola De Marco +1
We present the results of Chandra X-ray Observatory (CXO) observations of the planetary nebulae (PNs) NGC 40 and Hen 2-99. Both PNs feature late-type Wolf-Rayet central stars that…
X-Ray Emission by A Shocked Fast Wind from the Central Stars of Planetary Nebulae
Muhammad Akashi, Noam Soker, Ehud Behar
We calculate the X-ray emission from the shocked fast wind blown by the central stars of planetary nebulae (PNs) and compare with observations. Using spherically symmetric self sim…
Accretion by the Secondary in Eta Carinae During the Spectroscopic Event: I. Flow Parameters
Noam Soker
We examine the influence of the gravity of the companion (the secondary) to the massive primary star Eta Carinae on the winds blown by the primary and the secondary. The two winds…
