Yeshope sobtw i wanna ask u the note u gave me abt mass of star and how it wil end up u wrote tht between 1.4-3 neutron star if formed and above 3 explosion of supernova bt i kno tht after the explosion the neutron and black holes forms isn't it?
bt how if between 1.4-3 then neutron wil be formed bt supernova explosion is above 3?
Look, I just checked the Pearson book and it says black hole for over 3 solar masses! I'm confused now :Sbt how if between 1.4-3 then neutron wil be formed bt supernova explosion is above 3?
i don hve itLook, I just checked the Pearson book and it says black hole for over 3 solar masses! I'm confused now :S
see pg 85 :S the notes were from hodder acctually..
Whch book do u have with you then? The red one right?i don hve itbt i checked 1 bok my teacher gave me its nt edexcel maybe IB anyway i saw it nw it says 8-40 neruton star and above 80 black holes cuz it cnt be smaller solar masses resulting in neutron stars and supernova explosion above and it is the supernova explosion tht produces them ths wat i kno
ya then i thnk thts ryt i read nw againIn the revision guide it says: "If the initial mass of the star is greater than about 8 times that of our sun, this shrinkage will cause a can be so rapid that a supernova explosion occurs."
Okay now this is what I understand...
If the REMAINING core after the exposion is greater than 3 solar masses, then it forms a black hole but if its upto 3 solar masses it forms a neutron star.
Yes! When Hydrogen is over, it starts making He, which produces lesser energy than H fusion so the star cools and becomes a red giant. But there is enough energy for further fusion. Fusion continues till it reaches Fe and further fusion is not feasible and so gravity becomes pre-dominant and star suddenly collapses. This produces a huge burst of energy which is a supernova. Further elements are also formed in the explosionya then i thnk thts ryt i read nw againok i wanna ask u nw supergiant after hydrogen fusion is completed it becmes red giant and after fusion of heavier elements is completed it explodes?
thnx alotYes! When Hydrogen is over, it starts making He, which produces lesser energy than H fusion so the star cools and becomes a red giant. But there is enough energy for further fusion.

ur so welcomethnx alotok when they ask wat is supernova how 2 write the ans?
so it collapses due 2 gravity ryt?bcz the inner pressure deacreses and no fusion so after colllapsing due 2 high density it bursts:? and wat they mean by solar masses? and how 2 convert 2 solar masses cuz i saw ths twice in old past papersur so welcome
Its basically an explosion caused when the large-mass star collapses under its own gravity to release a huge amount of energy.![]()
Yes exactlyso it collapses due 2 gravity ryt?bcz the inner pressure deacreses and no fusion so after colllapsing due 2 high density it bursts:? and wat they mean by solar masses? and how 2 convert 2 solar masses cuz i saw ths twice in old past papers
and if it was wth corcle and dot so to convert it 2 normal mass i multiply?Yes exactly
Solar masses means as multiples of the mass of the sun, just simply divide the mass of the star (or whatever) by the mass of the sun and write the value u get along with M (and a small circle with a dot inside as a subscript after M).
Yupand if it was wth corcle and dot so to convert it 2 normal mass i multiply?
thnx alot
Ur welcome and sure no problemthnx alotso i must be leaving nw 4 the exam
1 hr is left pray 4 me

Thnx i'll talk 2 u inshalla after the exam so tht we can discuss our paper inshalla it wil be easy and we all wil do gdUr welcome and sure no problemI'll be leaving in an hour too
ALL THE BEST![]()
Ur welcome and sureThnx i'll talk 2 u inshalla after the exam so tht we can discuss our paper inshalla it wil be easy and we all wil do gdbye ttyl
all the best
Heyy how was ur exam?? it was a bit hard isn't it?Ur welcome and sure
Inshallah it will
U'll be on Happy Holidays now![]()
bye! n thanks! Same to u![]()
