[Story]How a K-type Star System Would Evolve?

This is an animation.
Captions has details.
[PSR Series]Timeline of an K-type Star - Planetball
This is about the evolution of a 61 Cygnus-like star(Mass is 0.65x Sun) and its planets, which is a hypothetical star system, but it’s mostly scientific.
Orange Dwarfs are sometimes called Goldilocks Stars, because they are more stable and live longer than Yellow Dwarfs like our sun, thus "Life-Sustaining". :D

[@cryoraptora303tm2]

This is probably the best use of the -ball genre I've ever seen. From what I can tell, you got all the science right, apart from 2 things. 1. By around ~10 billion years into the scenario, it's likely that the planets will have become unstable, leading some to being ejected, migrating out far away from the star, or possibly colliding. But this later occurred anyway so it's only a matter of timing. 2. In the description, you say that this star has a mass of ~0.65 solar masses. With this mass, it should achieve carbon burning and hence an AGB, but since it's close to the border I'll just assume this star was formed in an earlier phase of the universe, and the lower metallicity means it didn't achieve the density needed to burn helium. Apart from that, this was epic and I hope you'll make this for every class of star!

[@manw3bttcks]

not necessarily, planets themselves have things that limit their habitable lifetime like their cores running out of radio nucleotide energy to drive plate tectonics. It's thought that Earth might be more habitable because plate tectonics cycles various gases and keeps the continents from completely wearing down. But the K stars being long lived just means the star is less of a limit on the life time.

And also what was that planet at 94 AU out doing there, and why wasn't he there before? he didn't look like a passing-by star, he looked like a planet, so if he was part of the system, he should've always been visible.

First *draw* all pics, then oof them together using *Camtasia or other editors.*

Hey I love ur planets things

3:57, In third planet, it's habitable have a alien life, but why habitable zone green line is just half. But still habitable? Are they more sophisticated, or are their atmospheres much stronger? Although fiction, but hopefully there can be an explanation. :)

[@legendarypussydestroyer6943]

The back end of the planet signifies where the planet's actual position in relation to the habitable zone is. But yes I find it weird that the planet didn't go runaway greenhouse until much later but i think it's probably because the planet had a thicker atmo than earth so water requires a hgigher temp to evaporate.

K type stars are our best chance of finding life since they are in the midpoint between a sunlike star and a red dwarf.

[@WinVisten]

>Orange dwarf stars are best for earth-like planets Yes, yes they are.

[@clarkheredia5058]

Yet nobody talks about them, they talk about red dwarfs even though red dwarfs are shit because planets are tidally locked and behave more like moons of a large gas giant rather than planets, also red dwarfs are flare stars.

[@WinVisten]

@@clarkheredia5058 100% correct! The weird part though is that red dwarfs have stronger gravity than very large, massive stars, because they are denser. a red giant has weak gravity because even though it's massive, it's so diffuse that it doesn't really matter.

[@Ivon3976]

The star became a theoretical red subgiant at the ends of its life

[@gianfrancolabanca9305]

14:00 The asymptotic giant branch (AGB) is a region of the Hertzsprung-Russell diagram populated by evolved cool luminous stars this is a period of stellarr evolution undertaken by all low to intermediate-mass stars late in their lives. When a starexhaust the supply of hydrogen by nuclear fusion processes in its core, the core contracts and its temperature increases causing the outer layers of the star to expand and cool. Eventually, once the temperature in the corehas reached approximately 3x108 K, helium burning (fusion of helium nuclei) begins. The onset of helium burning in the core halts the star's cooling and increase in luminosity This is the horizontal branch (for population II stars) or red clump, or a blue loop for stars more massive than about 2 Mo. During AGB phase, the star swells up to giant proportions to become a red giant. again. im sorry but im tired of typing

[@Sundansulaku2023]

K type star doesn't have mass to turn in to abg
