That was a very long article for so little "where and when to look".

Ahh the event in 1054... Yeah that event was a banger!
never heard of these recurrent novae, got to look it up, sounds counterintuitive
You're thinking supernova, which happens only once. Novae were seen first as stars that would flare up, becoming a "new" star if it was too faint before to see. They are always a binary system, with the recurrent ones being a companion star that passes by periodically to deposit more material to flare up.
ah, i see, the word super makes all the difference here
There's also a hypernova. :D
🤯
And kilonova, which is when two neutron stars collide!
terra nova as well, which is when you boot up civ V
Like when Bowie and Frankie made Under Pressure?
What is kilonova explained?
A kilonova is an explosion resulting from the collision of two neutron stars, or a neutron star and a black hole. These events are extremely energetic, and can release as much energy in a few seconds as our Sun will produce in its entire 10-billion-year lifetime.
Thank you for posting the bit and the link.
Holy fuck that's so much energy!
How is it counterintuitive? Gas builds up, goes boom, repeat.
Usually stars don't build up gas. This one is part of a binary system, though, so like the other comment says, it's siphoning matter from the other one.
the counterintuitive part came for the standard candle supernovae already coming from binary systems and not being recurring, but somehow the recurrent ones manages to blow up with 1/100 of the energy, i am just learning this
Without reading the article, I imagine it’s a binary system where a white dwarf is siphoning gases from a star. When it reaches critical mass, it goes thermonuclear.
You are exactly right - how could this have possibly been a guess, lol.
I saw a video on this and this is pretty much how I remember it explained.
