X-ray Spectra and Light Curves of Cooling Novae and a Nova-Like
Bangzheng Sun, Marina Orio, Andrej Dobrotka +3
We present X-ray observations of novae V2491 Cyg and KT Eri about 9 years post-outburst, of the dwarf nova and post-nova candidate EY Cyg, and of a VY Scl variable. The first three…
What we learn from the X-ray grating spectra of Nova SMC 2016
M. Orio, J. -U. Ness, A. Dobrotka +17
Nova SMC 2016 has been the most luminous nova known in the direction of the Magellanic Clouds. It turned into a very luminous supersoft X-ray source between day 16 and 28 after the…
Constraining the accretion geometry of the intermediate polar EX Hya using NuSTAR, Swift and Chandra observations
G. J. M. Luna, K. Mukai, M. Orio +1
In magnetically accreting white dwarfs, the height above the white dwarf surface where the standing shock is formed is intimately related with the accretion rate and the white dwar…
CXO J004318.8+412016, a steady supersoft X-ray source in M 31
M. Orio, G. J. M. Luna, R. Kotulla +14
We obtained an optical spectrum of a star we identify as the optical counterpart of the M31 Chandra source CXO J004318.8+412016, because of prominent emission lines of the Balmer s…
Chemical and physical parameters from X-ray high resolution spectra of the Galactic nova V959 Mon
U. Peretz, M. Orio, E. Behar +5
Two observations of V959 Mon, done using the Chandra X-ray gratings during the late outburst phases (2012 September and December), offer extraordinary insight into the physics and…
