WB Chapter 1 - Stars Step1 Classification

In the Classification of a star it all depends on the magnitude of the star and from there they begin to determine other attributes of the star using known structures of nearby stars where it is easier to determine such. In this guide we do not have that option, so as we may begin with magnitude the way it is normally done. That would bring us on many different roads where the answers may not always be correct and there would be much work needed to accomplish this, so instead of a random magnitude where it is hard to determine the rarity of a star I will begin with the outright classification of the star.

The Morgan-Keenan spectral classification


The following illustration represents star classes with the colors very close to those actually perceived by the human eye. The relative sizes are for main sequence or "dwarf" stars.

The Lucifer Engine

Random generations and rulesets are often very time consuming, so while I have been writing these steps to help you build a great galaxy I have also been working on a script to randomly generate these details for you.

The prgram used to convert these scripts into data is TableSmith found at Mythosa - TableSmith.

Download this and my tables. Unzip the folder "The Lucifer Engine" and place it in "C:/Program Files/TableSmith/Tables"

If you installed it to the default location only ^

Read up on how to use TableSmith and in no time you will be using it fuently.

One thing to note is that you should only use the world builder and not the galaxy data. An there are parameters you can enter into the tables. Press F11 and you can tell the Table which type of galaxy to generate. Also having a value of random.

WB Chapter 1 - Galaxies Step3 Location2

Step3:
For each of the different types of galaxies we go through and determine if the Solar System is within a cluster and of which type it is.

WB Chapter 1 - Galaxies IV - Clusters

Star clusters  are groups of stars. Two types of star clusters can be distinguished: globular clusters are tight groups of hundreds of thousands of very old stars which are gravitationally bound, while open clusters, a more loosely clustered group of stars, generally contain less than a few hundred members, and are often very young. Open clusters become disrupted over time , but cluster members will continue to move in broadly the same direction through space even though they are no longer gravitationally bound; they are then known as a stellar association, sometimes also referred to as a moving group.

WB Chapter 1 - Galaxies Step2 Location1

Step2:
We make a roll on 1d100 to determine the location of the Solar System inside of a Spiral Galaxy.

1-18 - Your Solar System is located in the Galactic Bulge. If your Galaxies Classification is Sa or SBa then the Age Mod is +3 if it is Sb or SBb then roll 1d10 if it is 6-10 then the Age Mod is +3 otherwise there is no age mod.

19-86 - Your Solar System is located in the Galactic disk, which includes the arms. No Age Mod is applied here

87-100 - Your Solar System is in the Galactic Halo, all the stars located here are of the Population II type so apply an Age Mod of +3

WB Chapter 1 - Galaxies III - Structure

The structures of different galaxies can vary in size and detail, so in this article we are just going to discuss the different locations in spiral type galaxies

Spiral galaxies consist of four distinct components:

• A flat, rotating disc of (mostly newly created) stars and interstellar matter
• A central stellar bulge of mainly older stars, which resembles an elliptical galaxy
• A near-spherical halo of stars, including many in globular clusters
• A supermassive black hole at the very center of the central bulge

Word Builder Guide Index

This is an index for my World Building Guide they will be arranged in order for easy access.

Finally got the book

I finally obtained my new book yesterday before I had to leave for TAFE.

The contents are pretty strong with great scientific explanations but lacking in quantity. here is only 2 pages on galaxies and it only explains the basic types. Either way it is going to be a great resource in time to come using some of the great content.

New book on the way

 I have ordered a new book. The shipping isn't cheap either and I don't want it in a month so I found another vendor just one suburb away but they order from overseas in out of stock print, so next month I will give a small review of what I think of the book. I got myself the science fiction world building guide by Stephen L Gillet. I am hoping that it will give me some very insightful ideas and help me behind the scenes. On the other hand I got some role playing books on world building also, they may not be the best (except for Gurps Space 4e) but they were given to me by an ex player/GM who felt that you can be too old to have an imagination anyway that doesn't matter.

WB Chapter 1 - Galaxies Step1 Classification

Step 1:
To determine the type of Galaxy you will eventually end up in roll on 1d100

1-12 - Galaxy is of Irregular shape. You will find very little amount of planets orbiting stars in this type.

13-28 - Galaxy is of Elliptical type. Very few planets orbit stars and the stars found here are older (Population II) than other types so add an age modifier to the system of +5

29-94 - You rolled a Spiral Galaxy. Because Spiral Galaxies are the main focus of this guide they will be more complicated than the other types but you can still use the other types for your planet just make sure to take notes on the different properties.

95-100 - NONE. This type isn't really a type a system can be rogue and not have any Galaxy to belong to. It may still be in a Globular Cluster or any other formation, maybe even none. These setups tend to be very unstable and generally after some time being rogue the system will fall apart and will be unable to support planets. It is Dim and very cold in these systems.

WB Chapter 1 - Galaxies II - The Different Types

Galaxy classification is a system used by astronomers to divide galaxies into groups based on their visual appearance. There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the Hubble sequence, devised by Edwin Hubble. I will be using this system in my explanations.

Galaxy Picture

 I haven't made a post in a while but that's life.

So anyway I have not given up I just need to make some adjustments and hopefully I will get a little bit more enthusiastic about my creation.

So for your enjoying pleasure I would like to produce a photoshop creation of mine.

WB Chapter 1 - Galaxies I - How do they form?

 The first part of many parts in my World Building articles and exercises is to do with galaxies, how do they form, what types are there, what shapes, how old etc.

Galaxies in the early universe didn't exist because there just hadn't been enough time for them to come together. If we look back at the big bang we see that it pushed all that matter out in a very fast expansion, after some time this matter began to cluster together forming dust clouds on massive scales, these clods were super hot and very rich in star materials. As they clustered together more and more they started to hold themselves together under gravitational force, all this kept happening for many millions of years until these fiery balls of liquid started to ignite all over the place.

WB Chapter 1 Intro

 This first chapter deals with all the date needed to develop a Star System without the need of a degree(not that I have one). I have split it into multiple sections just to keep things short, I will post one step (unless it is a multi-step process to get the final result) at a time after reviewing it and making sure it works, I will show examples along with the guide to give a better idea of how things will work out.

Welcome Two, Three All..

 Welcome if you are reading this, I have a driving blur in my head that just keeps crashing, so I thought maybe I could write about my life and all the interesting things I have done and will do. So to get started let me tell you who I am and what I do.

My name is Jason I live in Melbourne, Australia at the time of writing this (I moved around a lot as a kid and probably have it in the blood), I am currently studying at Lilydale TAFE doing my Cert IV in IT(Multimedia). I have just started this course and I see it as the start of my life, where I am in charge of myself. The internet is my escape and now I can write about it.
