1991bglike
1991bglike is a classification used in astronomy to describe a specific type of supernova. Supernovae are powerful stellar explosions that can briefly outshine an entire galaxy. Type I supernovae are characterized by the absence of hydrogen lines in their spectra. Type Ia supernovae, a subclass of Type I, are particularly important because they have a consistent peak luminosity, making them useful as standard candles for measuring cosmic distances.
The designation "1991bglike" refers to a specific subtype of Type Ia supernovae that exhibit unusual spectral
These peculiar supernovae were first identified around the year 1991, leading to their classification. While not
