The life of an average star
An average star can be used to refer to a star that has properties that are typical of stars in general. For example, the Sun is often considered an "average star" because it has characteristics that are similar to those of other stars in terms of its mass, temperature, and luminosity. The Sun is a G-type main-sequence star, with a mass of about 1.989 x 10^30 kilograms, a diameter of about 1.4 million kilometers, a surface temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit), and a luminosity of about 3.8 x 10^26 Watts.

Parenting tools are playing an increasingly important role in modern parenting. They not only help parents take better care of and educate their children, but also provide convenient methods and resources to support parents' parenting decisions. For example, growth tracking applications can help parents record their children's growth milestones, remind them of important matters such as vaccination, etc; Educational applications provide abundant learning resources and interactive games to stimulate children's interest in learning. In addition, parenting tools can also provide parents with parenting knowledge and advice, helping them better understand and respond to their children's growth needs. This is a mind map of Dharma Parenting Tools. The map contains six main branches, namely Routines Improve Family Dynamics, Manage Melldowns&Cultivate Better Behavior, Anticipate and Adapt, Discover Yourself and Child, Heal Yourself, Attention and Admission. Each main branch has detailed descriptions of multiple sub branches. Suitable for people interested in Dharma Parenting Tools.
- Pure consciousness and Dharma
In this mind map, we will explore the various branches that are related to pure consciousness and Dharma, including mental health counseling, inspirational speaking, TM instruction, and more. We will also delve into the deeper questions surrounding suffering and the purpose of life. Join us on this journey of self-discovery and spiritual growth.

The Evolution of an Average Star
Begins as an
Innerstellar Shroud of Gas
A star originates from a large cloud of gas
Helium
Hydrogen
The temperature in the cloud is low enough for the synthesis of molecules.
As molecules form and synthesize it becomes an
Average Star
Is between 1 to 3 masses
First it will stay on the main sequence for 10 billion years or longer.
When the core's hydrogen is spent, it enters the end point stage of life.
Because the process of fusion within its core ceases to generate fuel, it shrinks, increasing in temperature.
As the hydrogen shell surrounding the core contracts, it becomes hot enough to burn, causing the outer layers to expand and then it begin its transfromation.
In the core, helium fusion begins causing its first transformation where a
Planetary Nebula
The outer gaseous envelope will blast away, releasing some of its mass.
Creates a
Red Giant
When the star becomes a red giant, it will begin its 2 billion-year trip out from the main sequence.
It classification moves to the upper right portion of the HR Diagram
It grows to a size of 10 to 100 times its previous mass.
A flare causes the outer layers to expand due to an increase of hydrogen fusion in a shell enclosing a non-burning helium core
Because of its gravitational force until its core will continue to collapse into itself causing it to pressurize while still remaining hot where it transitions again.
Next comes a gradual reduction to a
White Dwarf
Because they are so little and faint, they are difficult to see.
Athough it is hot it moves to the lower left corner of the HR Diagram due to its dimness.
As it cools, it travels to the HR Diagram's bottom right.
It is made up of a dense kind of material object known as "degenerate matter."
One cubic centimeter of degenerate matter weighs approximately one ton.
