Just fact sheets related to space! The non-astrophysics, beginner-friendly versions. Lose yourself in space, just how I did! ![[astro-background.png]] *Bonus: If this road is facing directly east, approximately what time of the year was this 'photo' taken?* [[Home|Navigate back to the main, MAIN menu by clicking here!]] Note: There are A LOT of links in this article. So be warned! # Magnitude - [["Brightness" - Luminosity and Magnitude]] - Got a vendetta against bright lights? Learn to model how bright they actually are on cosmic distances here! We're taking the fight to functional infrastructure to protect our night skies! # Stars - [[Stars (Astro)]] - The intro to stars. The jumping base to the absolute chaos that is stellar physics. Begin a journey of a lifetime (for some people, quite literally) here! This also needs a rework. - [[M-Type Stars (Astro)]] - [[K-Type Stars (Astro)]] - [[G-Type Stars (Astro)]] - [[F-Type Stars (Astro)]] - [[A-Type Stars (Astro)]] - [[B-Type Stars (Astro)]] - [[O-Type Stars (Astro)]] # Stellar Remnants - [[White Dwarves (Astro)]] - All about White Dwarves - no equation of state yet! - [[Nebulae (Astro)]] - From the Pulsar Wind to the Planetary Nebulae, hop in to learn about these giant, expanding dust clouds! # Variable Stars - [[Variable Stars (Astro)]] - Go over the many, many types of variable stars here! - [[Cepheid Stars (Astro)]] - Yes, Cepheids were important enough to receive their own article. Learn about them here! - [[BY Draconis Variables (Astro)]] # Life Cycle of stars - [[Protostars (Astro)]] - Protostars are baby stars, dotted around gas clouds in galaxies. From the Herbig-Haro to T Tauri stars, we've got the whole shebang! - [[Precursor Stars (Astro)]] - All about the fun, mostly-hypothetical explanations for certain peculiar stars! - [[The Birth of Stars (Astro)]] - Learn all about star births! - [[The Death of Stars (Astro)]] - From the moment the core collapses inward on itself, or when the stellar wind gets untenably hot for the outer layers of a star, learn all about the - [[Star Clusters (Astro)]] - Stars form in dense, dense clouds. Often times, this means that they form *clusters* - huge agglomerations of stars that drift through space gravitationally bound to each other. Learn about the two types of cluster: Open and Globular, here! - - [[Red Giants and the Pre-Death of Stars (Astro)]] - Red Giants, stars in their death throes. We'll be looking past a simple 'runs out of helium' explanation for these puffy giants and instead peering into the enigmatic interiors of these stars! # Stellar Oddities - [[Brown Dwarfs (Astro)]] - Learn the special attributes of brown dwarves here! - [[Populations of Stars (Astro)]] - Astronomers categorise stars into different types of *populations.* Learn about them here! # Attributes of Stars - [[Metallicity (Astro)]] - Stars aren't all hydrogen and helium. Carbon, oxygen and a potluck of other materials mix into these hulking, burning spheres. - [[The HR and Colour-Magnitude Diagrams (Astro)]] # Fusion in Stars - [[The CNO Cycle (Astro)]] - [[The Proton-Proton Chain - Intro to Fusion Mechanics (Astro)]] - [[The Triple-Alpha Process and Beyond (Astro)]] # Physics Primers - [[Briefer Intro - Radiation and Spectra (Astro)]] - The astronomer's guide to spectral lines.
