WASHINGTON, Oct. 13, 2022 /PRNewswire/ -- Astronomers using SOFIA, the Stratospheric Observatory for Infrared Astronomy, discovered something unique: a new type of stellar outburst that had never been seen before in the type of system under study.

Key Points: 
  • WASHINGTON, Oct. 13, 2022 /PRNewswire/ -- Astronomers using SOFIA, the Stratospheric Observatory for Infrared Astronomy, discovered something unique: a new type of stellar outburst that had never been seen before in the type of system under study.
  • This type of nova occurs when the disc around the white dwarf becomes unstable causing an outburst that is much less powerful and bright than a classical nova.
  • The cataclysmic variable SOFIA observed V1047 Cen, a white dwarf and its Sun-like companion erupted as a classical nova in 2005 (Nova Centauri 2005).
  • Taken together, the data started to make more sense, and they realized they had come across something unique a new type of stellar outburst that had never been seen before in this type of system.
