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…
Optical observations of "hot" novae returning to quiescence
P. Zemko, S. Ciroi, M. Orio +10
We have monitored the return to quiescence of novae previously observed in outburst as supersoft X-ray sources, with optical photometry of the intermediate polar (IP) V4743 Sgr and…
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…
Multi-mission observations of the old nova GK Per during the 2015 outburst
P. Zemko, M. Orio, G. J. M. Luna +3
GK Per, a classical nova of 1901, is thought to undergo variable mass accretion on to a magnetized white dwarf (WD) in an intermediate polar system (IP). We organized a multi-missi…
