Optical Observations of SAX J1808.4-3658 During Quiescence
C. J. Deloye, C. O. Heinke, R. E. Taam +1
We observed the accreting millisecond pulsar SAX J1808.4-3658 with Gemini-South in g' and i' bands, nearly simultaneous with XMM-Newton observations. A clear periodic flux modulati…
Common Envelope Mergers: A Possible Channel for Forming Single sdB Stars
Michael Politano, Ronald E. Taam, Marc van der Sluys +1
We quantify an evolutionary channel for single sdB stars based on mergers of binaries containing a red giant star and a lower mass main sequence or brown dwarf companion in our Gal…
On the Properties of Inner Cool Disks in the Hard State of Black Hole X-Ray Transient Systems
Ronald E. Taam, B. F. Liu, F. Meyer +1
The formation of a cool disk in the innermost regions of black hole X-ray transient systems in the low hard state is investigated. Taking into account the combined cooling associat…
The most massive progenitors of neutron stars: CXO J164710.2-455216
K. Belczynski, R. Taam
The evolution leading to the formation of a neutron star in the very young Westerlund 1 star cluster is investigated. The turnoff mass has been estimated to be 35 Msun, indicating…
The Thermal Evolution of the Donors in AM CVn Binaries
Christopher J. Deloye, Ronald E. Taam, Christopher Winisdoerffer +1
(Abridged) We calculate the full stellar-structural evolution of donors in AM CVn systems formed through the WD channel coupled to the binary's evolution. Contrary to assumptions m…
Accretion Disk Spectra of the Brightest Ultra-luminous X-ray Source in M82
Feng Yuan, Ronald E. Taam R. Misra, Xue-Bing Wu +1
Emission spectra of hot accretion disks characteristic of advection dominated accretion flow (ADAF) models are investigated for comparison with the brightest ultra-luminous source,…
