In this video I will explain how the formation of the star follows the Hayashi track.
Very good series of lectures, thank you.
So let me get this right: protostars>stars>supernova etc>more stars>heavier elements>stars and planets>Michel v Biezen created to give lectures on star formation. Nice.
These numbers are incredible, and incredibly valuable. Thanks!
Great lecture. Very informative...
and many other sort of stars live on earth. nice to picture an actual star and think of them.
Latest data from Juno spacecraft suggests that Jupiter has a massive core of metallic hydrogen and rock. So probably the sun also.
At stage temperature 6 explain the "faint young sun paradox"? Also is stage 6 the time when the new star setup an internal " core structure ". Thanks
The "faint young Sun paradox" may not be a paradox at all. Earth's climate is very complex and dependent on many factors including where the location of the continents were bilions of years ago. We simply do not know enough information of early Earth to determine that there was a paradox at all.
@@MichelvanBiezendo know henyey track thats for stars that is more massive than 0.50 times sun mass
Sir after 15Million Kelvin at centre of star will the temperature increases afterwards??
The core temperature of the Sun will slowly increase over time as the nuclear fusion rate increases over time.
@@MichelvanBiezen oo ok sir thank a lot
Excellent, clear lectures. Thanks !
You are welcome! 🙂
Sir i want to know what is henyey track
It is the "path" taken on the HR-diagram from the protostar stage to the main sequence stage. The path takes the star from the upper right corner of the diagram to the main sequence curve. (The end position depends on the mass of the star).
