If a distant point of light with 100 solar luminosity units increases within 3 days to 100,000 units…..?
hydrogen and helium completely dominate the light spectrum during brightening, and the spectral lines are blue shifted compared with the light from the light source before brightening, what would you be observing?
I would say it’s a supernova.
The blue relative shift would be due to the sudden collapse before explosion.
No quasar has anything as small as 100 x solar luminosity.
Three days is a typical time period for observation of supernova events.
Hydrogen and helium are the elements which would dominate the upper layers of a red giant about to pop.
