Hi all,

[qualifying comment- please forgive me if this is a stupid question]


I have been working my way through the Astronomy 162 podcast and reading this forum (lately the discovery of a nova) and was wondering if anyone has captured the "birth" of a star, i.e. when the effects of nuclear fusion are first noticeable at the star's surface?

I imagine that the event would generate an increase in IR, as well as visible light, as compared to the pre-fusion state. Or is the process gradual- that is, it takes time for fusion to really get going?

Although it would be a bit like looking for a needle in a haystack- it seems that needles are found all of the time...

cheers.
