The reason main sequence has a limit at the lower end is because of temperature and pressure. The lower limit exists in order to exclude stellar objects that are not able to sustain hydrogen fusion.

A sequence of steps leading to a desired end?
Algorithm
What is the missing numbers in the sequence 4 24 144 864?
It should begin with 2/3 and end with 6*864 = 5184
Is there a number past infinity?
No because technically, infinity is not a "number" it is a concept that means without limit, bound or end. so infinity+1=infinity infinity2=infinity and so on.
Bottom up approch?
A term usually used in business studies. Its a method of approaching organisational issues from the perspective of the lower end of the organisation (workers).
What things are infinite?
numbers!! :D i say numbers because there is no limit to numbers. you could write a billion or a number with a billion zeros and another thing, love there will be no end to love .... the 2012 apocalypse is correct...
The main sequence has a limit at the lower end because?
e. there is a minimum temperature for hydrogen fusion.
How are stars on the upper left end of the main sequence different from those on the lower right end?
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
What type of star would be shown at the lower right end of the main sequence on the H R diagram?
Depending on how "low" on the chart it will either be a red dwarf or a PMS (Pre-main sequence) star.
In which class either lower limit or upper limit is missing?
open end class
What is the Birth Line in the Hertzsprung-Russell Diagram?
If you are faced with multiple choice, it is NOT, "The Extreme Lower End of the Main Sequence." I got this answer wrong on a recent astronomy quiz.
What phase do stars end their main sequence as?
red supergiant
What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
When does the main sequence star phase of a star end?
The "main sequence" is the region (on the HR diagram) for stars which burn hydrogen-1. Once stars use up most of their hydrogen-1 (and have significant amounts of helium-4), they leave the main sequence.
What is the difference between an infinite sequence and a finite sequence?
A finite sequence has a beginning and an end, whereas an infinite sequence has no end.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
What color is the star alioth?
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:
Will Altair soon become a supernova?
Highly unlikely in our lifetime. Altair is still on the main sequence and probably has a few billion years left on it. Even when it comes to the end of the main sequence, it may not have enough mass to become a supernova.
