What it is Filled
A class of astronomical X-ray sources emitting mainly very low-energy X-rays with luminosities comparable to bright X-ray binaries, interpreted in most cases as white dwarfs steadily burning hydrogen accreted from a companion star; supersoft sources are candidate progenitors of Type Ia supernovae and were recognised as a class from ROSAT observations in the early 1990s.
Why it exists Filled

Identity and identifiers required Filled

- Wikidata: Q1060667 (https://www.wikidata.org/wiki/Q1060667)
Direct properties required Filled
- Characteristic photon energy: keV - The low-energy X-ray spectrum is measured with an X-ray detector and interpreted with corrections for instrumental response and intervening absorption.
- Effective emission temperature: K - Temperature is inferred by fitting an emission model to the observed spectrum and depends on the chosen model.
- Radiative luminosity: W - Luminosity is inferred from flux, distance and absorption estimates with the spectral band or bolometric correction stated.
Recognition required Filled
- Very soft X-ray spectra
- High luminosity
- Ordinary X-ray binaries emit harder X-rays
- Not visible optically as such; point sources in soft X-ray images.
