Emission line in spectrum of a sun

AI Thread Summary
The discussion revolves around the unexpected presence of a strong hydrogen alpha emission line in the spectrum of a star, which typically would show absorption lines instead. The user suspects the star is a B class young hot star due to this anomaly. Other participants suggest that the question might be better suited for a homework section, indicating its academic nature. The significance of the emission line could relate to the star's temperature and density conditions. Overall, the conversation highlights the complexities of stellar spectroscopy and the implications of emission versus absorption lines.

Hi guys, this is a homework question, but i didnt think it belonged with the physics questions. I have the spectrum of a star, it has hydrogen gamma and hydrogen beta absorbtion lines, but a very very strong hydrogen alpha emission line. What is the significance of this, I would expect a hydrogen alpha absorbtion line. I figured this to be a B class young hot star.

Thanks!

I think you need to place this in one of the homework sections even if it isn't your average physics question. Hopefully someone will be able to help you there!
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
