This goes back. Thank you, AstroCat, for going back and doing this type of video again.

Should he do brown dwarf

[@moisesmoreira6645]

It's impressive that white dwarfs post-red giant phase cool down really quick and when it becomes older, the white dwarf cool down more slowy than before. (Sorry if i mistake a word i'm still not really fluent at english)

[@its_jocel3580]

Bro. White dwarf coolds down like billions, trillions, quadrillions and quintillion of years. U cant say its quick.

[@moisesmoreira6645]

Yes, but the speed of cooling depends from the age and composition of the white dwarf, that on the video

[@nilnull5457]

Black body radiation rates are highly dependent on temperature, the lower the temperature the slower is the cooling rate

[@moisesmoreira6645]

​@@nilnull5457thanks for explaining

[@vladtepes4526]

@@moisesmoreira6645 Also more massive white dwarfs cool down slower because of smaller radius and surface - higher degenerate electron gas pressure therefore higher density is needed to counteract gravity.

THE LEGEND IS BACK! almost 100k too!

[@interopsty]

CONGRATS ON 100K! road to a million!

[@Ragdollcat4]

Didn't know that black dwarf would take 1 trillion years to become safe

[@endercrafto3]

Finally he's back What are you working on right now (irl)? The 100k mark is *so* close

[@StardustWX]

When the world needed him the most, he returned

[@Unremembered.]

Just came back to the channel and as I saw your subscriber count I was surprised. (Almost 100k congrats!) A masterpiece like always, keep up the good work!

[@AlphaAreospaceReal]

Ikr (also at 102k now wow)

[@tanker1425]

i like how the music tempo slows down as the speed of the cooling does too

[@ral117]

Ironically, the music fits. Great selection. I thought the stars in the background would also starts to dim as the years go on

[@matte7128]

Heya dude, i found your channel when it had 10 or 20k subs and am so happy to see that you're almost at 100k you deserve them all, your contents are fantastic, intresting and explains space without making you bored, i hope your channel will continue to grow more and more

[@sillyserb25]

That's also the time when I first saw his channel

Ah. Astrocat. I think I found him when he was under 1K using my TV account.

Yes

Why are white dwarfs so cute 🥰

[@rainyanimatez5830]

Congrats on 100k btw

[@Jaythegoat_yt]

Do not try to touch a black dwarf star remember if white dwarf stars are extremely dense so black dwarf stars will be to and you will be crushed flat if you stepped foot on it

[@messier8379]

1 teaspoon of white dwarf is over 5.5 tons.. But it would be a solid as Diamond since they were composed of Carbons as they cooldown.. If i want a Ring that has a diamond from a Blackdwarf that small grain of Diamond would be still heavy as 1 ton

[@error4o461]

Great video!

[@roboticearth3506]

Alright let’s be honest guys this master have make many videos, but subrate is still slow, can we just respect how much efforts he puts in? I,m being really honest

[@AstroY19]

Hello Astrocat, ive been a subscriber for a long time now, and as ur reaching 100k, i had an idea for you to make the creation of the universe to now, as a celebration of ur 100k. Keep on the hard work🫡

[@jurisjancevskis9076]

Hey @AstroCatz , i want to make my own star system but idk the luminosity and all the calculators demand variables i dont know about (and cannot calculate, such as magnitude) These are the main variables for this (made-up) star, based partly on sigma draconis Mass: 0.78 sun Temp: 5012 K Distance: ~35 light years from earth

[@Goldev]

I hope you get helped. This interests me too

[@jurisjancevskis9076]

@@Goldev I just wanna make a cool system - maybe 4-5 planets

[@AquaranSocialistRepublic]

This is the correct formula for the luminosity of a star: L = (T/5778)^4 * (R/695700)^2 L being the star's luminosity in solar luminosities, T being the star's temperature in Kelvin, and R being the star's radius in kilometers. Notice how the star's mass doesn't affect its luminosity?

[@jurisjancevskis9076]

@@AquaranSocialistRepublic how do I calculate star radii And what are the numbers in the equation, those being 5778 and 695700 Do you divide T by 5778?

[@Mapper_Space]

You should do timeline of alpha centauri preferably based on new data, like how A and proxima or 4.85 billion years old and b is 5.3 billion years old. Maybe include that b gets captured and possibly proxima, but proxima has the same age as a, so its less certain.

[@ThatBoredPyrexical]

It's sad how the sun will beat the shit outta of the earth when it turns into a red giant

[@messier8379]

Our Earth has 90% chance of survival when Sun's started to Expand...the inner planets orbit would also expand at slow phase it theoritically put Earth at 3AU to 4AU distant at late Red Giant phase...when Sun had reached its maximum size as Red Giant our Earth would be far enough to not consumed by it.. But theres also some planets that survived their Parent star Red giant phase like the two planets called Kepler70b and 70c but they were once Gas Giants..
