Stars condense slowly out of coulds of hydrogen. But the final stage is quick as the star starts to radiate at a very high temperature. Stars start very hot so they are on the left of the HR diagram (the main sequence). How high up they are on the diagram depends on their mass.

Why are there no stars bluer on the main sequence?
No stars blue? A star's colour depends on it's temperature. A blue star must be very hot in order for it to glow blue. All stars in the main sequence sre only hot enought to glow yellow, not hot enought to glow blue.
Is the milky way a main sequence star?
All stars that are in hydrostatic equilibrium are on the main sequence, where outward thermal pressure from the hot core is balanced by the inward gravitational pressure from the overlying layers.See related questions
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
When geologists place rocks in their proper sequence of formation this is called dating?
No, when geologists place rocks in their proper sequence of formation, it is called relative dating. This method does not give an exact age, but it establishes the order in which rocks formed based on their position in a sequence. Absolute dating techniques are used to determine a specific numerical age of a rock or fossil.
How old was planet Mercury when it was made?
Planet Mercury was zero years of age when it was made.
What has the author Mario H Pedreros Avendano written?
Mario H. Pedreros Avendano has written: 'A new approach to zero-age main sequence fitting'
A star located off the main sequence indicates what?
A star located off the main sequence indicates that the star is at a different stage in its life cycle. This could be due to factors such as age, mass, or chemical composition. Some common types of stars found off the main sequence include red giants, white dwarfs, and supergiants.
What is the significance of zero-age main sequence in the evolution of stars?
The zero-age main sequence is a critical stage in the evolution of stars where they first begin to fuse hydrogen into helium in their cores. This marks the start of their stable phase of energy production. It is significant because it determines a star's mass, luminosity, and lifespan, providing important insights into its future evolution and eventual fate.
Are stars on the main sequence hot?
Yes, stars on the main sequence are hot. They generate energy through nuclear fusion in their cores, which creates the immense heat and light that we see and feel from Earth. The temperature of a main sequence star varies depending on its size and age, with hotter stars being more massive and younger.
Why would an old main sequence star have more helium?
Stars make Helium as they shine - so more with age.

How old are dic and dom off cbbc?
zero + their age = their age.
Which two factors determine the characteristics of a star?
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
Is the milky way a main sequence star?
All stars that are in hydrostatic equilibrium are on the main sequence, where outward thermal pressure from the hot core is balanced by the inward gravitational pressure from the overlying layers.See related questions
