Well, they are not actually confused with planetary nebula. They are planetary nebula. It is because they look like little planets, but are not. It was a mistake in our presentation. Sorry to confuse you.
Elisa, red giant stars can reach sizes of 100 million to 1 billion kilometers in diameter (approximately 100 to 1,000 times the size of our sun). When the stars go into this stage their energy is spread across a greater area, causing them to become cooler (2,200 to 3,200 celsius which is a little over half as hot as the sun). This is also why they earned the name red giants, their temperature change caused a color change.
It stops at iron because nuclear reactions involving iron don't release energy and so it builds up in the core until it can't resist gravity anymore and thats when it collapses into a supernova explosion
We made a mistake in our presentation. They are not confused with them, they are planetary nebula. It is part of the death of a low mass star. It is called that because they looked like planets but are not. The statement in our presentation was suppose to be that they are often confused for a planet. Sorry for the confusion.
Dying stars go through a period where they gain a second life (zombie phase) in which they still continue to shine as bright, if not brighter, than when they were alive.
Why is the death of a low-mass star confused with a planetary nebula?

DeleteYou said mass is the most important property, but how high and low do the masses get. Also at what mass does it make it either hotter or colder.

DeleteNick-Planetary nebula are just one phase in the death of a low mass star. They end as a white dwarf.
ReplyDeleteWhat is the average sizes of an average star and red giant?
ReplyDeleteAn average star is like our sun, it has a diameter of 1.4 kilometers. A Red giant's diameter will expand to 10 to 1,000 times that of the Sun.
DeleteDuring the multiple shell burning phase, why does it stop at iron?
ReplyDeleteIt stops at iron because nuclear reactions involving iron don't release energy and so it builds up in the core until it can't resist gravity anymore and thats when it collapses into a supernova explosion
DeleteCould you explain how the death of a low mass star can be confused for a planetary nebula please?

DeleteHow long is the star in the red giant phase?
ReplyDeleteKelli, a star can spend anywhere from one thousand years to a billion years in the red giant phase.

DeleteHow did the name Zombie phase come about
ReplyDeleteDying stars go through a period where they gain a second life (zombie phase) in which they still continue to shine as bright, if not brighter, than when they were alive.
