#supernova;

There are two common routes to a supernova: either a massive star may run out of fuel, ceasing to generate fusion energy in its core, and collapsing inward under the force of its own gravity to form a neutron star or a black hole; or a white dwarf star may accrete material from a companion star until it reaches a critical mass and undergoes a carbon detonation.

In either case, the resulting supernova explosion expels much or all of the stellar material with velocities as much as 10% the speed of light (or approximately 30,000 km/s) and a strong shock wave forms ahead of the ejecta. That heats the upstream plasma up to temperatures well above millions of K. The shock continuously slows as it sweeps up the ambient medium, but it can expand over hundreds or thousands of years and tens of parsecs before its speed falls below the local sound speed.

Bold the ones that apply to your character:

An arm raised up, parallel with the pale-blond’s head. “Come one!” he called, fixing his half-up ponytail with his free hand. “Come all!” His other arm raised up to complete his T-shaped pose as he stood atop a makeshift pedestal he’d made out of a discarded crate.

“Line up right here to fight the greatest duelist in all of Prouzagt! My flurry of strikes will leave you speechless! My form is impeccable! My--”

As people begin to file out from the hall where the talent show was held, an agent from NOVA quickly approaches you with a formal handshake. “Hello there. I’m from NOVA Entertainment. I can’t help but notice your great potential during the harmonization workshops this morning.” The woman flashes a hint of a smile as she plucks out a calling card from her purse. “Call our front desk any time you’re up for an audition, will you?”

You know those nights where something so impacting occurs seemingly out of the blue, and you just know that you’ll remember it forever? Well, for Dawon, tonight was that night, and to say it had been eventful would be one big understatement. It was the last full day of summer camp, and the vocalist had found herself determined to turn it one hell of a memory. She’d succeeded, of course, and as she made her way off of the stage, she was certain of this. At this point, she could only pray that she’d made as good of an impression as it had felt.

It had been a memorable performance — or it had been in her eyes, at least. In a way, it was hard for Dawon to believe that it was truly over; this was her first time performing in front of an actual audience outside of the theater, and in a way, it felt all too surreal. Her heart was still racing as she watched the performance that followed — it was a soothing enough song, and it certainly helped to ease Dawon’s nerves a little. The fact that it was none other than Kim Jinwook onstage did well to help even further — he was someone in which Dawon was proud to call a friend.

Whereas such a meaningful performance should have been the most notable thing of the night by a landslide, what came afterward certainly comes close to the title. As everyone began to exit the hall now that the talent show had finally reached its end, Dawon was stopped rather abruptly by a woman offering a hand. Dawon didn’t know her — yet somehow, it felt as though the woman certainly knew of her. In no way did it matter that she hadn’t referred to Dawon by name — she was grateful to have been recognized at all. In return, Dawon hesitantly reaches out her hand, accepting the handshake.
