X-ray observations of Nova Sco 2023: Spectroscopic evidence of charge exchange
Sharon Mitrani, Ehud Behar, Marina Orio +1
The super-soft source (SSS) phase of a nova eruption, observed a few days after the outburst, usually displays an absorbed X-ray thermal continuum with absorption features, emitted…

Mixing of hot shocked plasma with cold gas in Nova YZ Ret 2020
Sharon Mitrani, Ehud Behar, Jeremy J. Drake +5
The origin of bright X-ray emission lines that appear late in a nova eruption remains largely a puzzle. We present two high-resolution X-ray grating spectra of the classical nova Y…
