X-ray Spectra from Plasmas with High-Energy Electrons: kappa-distributions and e-e Bremsstrahlung
Xiaohong Cui, Adam R. Foster, Takayuki Yuasa +1
Shocks, turbulence and winds all influence the electron velocity distribution in hot plasmas, exciting lower-energy electrons and generating a high-energy (typically power-law) tai…
An Estimation of the White Dwarf Mass in the Dwarf Nova GK Persei with NuSTAR Observations of Two States
Yuuki Wada, Takayuki Yuasa, Kazuhiro Nakazawa +3
We report on X-ray observations of the Dwarf Nova GK Persei performed by {\it NuSTAR} in 2015. GK Persei, behaving also as an Intermediate Polar, exhibited a Dwarf Nova outburst in…
Eta Carinae's Thermal X-ray Tail Measured with XMM-Newton and NuSTAR
Kenji Hamaguchi, Michael F. Corcoran, Theodore R. Gull +12
The evolved, massive highly eccentric binary system, eta Carinae, underwent a periastron passage in the summer of 2014. We obtained two coordinated X-ray observations with XMM-Newt…
