1–2 gauss
what are dark patches on the Sun’s
photosphere?
sunspots
what is interplanetary magnetic field

Sun’s magnetic field into space
cantuman H membentuk
He and C
tenaga solar dihasilkan dari
cantuman H
cantuman nukelar ada 2 iaitu
- Rantaian proton-proton (PP)
2. Rantaian carbon-nitrogen-oksigen (CNO)
hasil cantuman
4 nukleus H + 2 e
apa jadi kepada electron bebas?
bergabung dengan H membentuk nukleus yang ada 2 p, 2 n
perbezaan PP dan CNO
PP cantum terus dengan He, CNO ada proses pertengahan sebelum haba dihasilkan
kekerapan PP dan CNO
PP - 88%
CNO - 12%
how does the Sun dies?
l exit the main sequence and turn into a
red giant. it will grow so large that
it will engulf Mercury, Venus, and probably Earth
what is luminosity?
total energy radiated by the Sun
