The discussion focuses on the search for real images of Balmer absorption lines in stars at different temperatures, specifically a 10,000° Kelvin star with strong lines and a colder or hotter star showing weak lines. Participants suggest searching for "stellar absorption spectra" on Google Images to find suitable high-resolution images. There is also a concern about proper credit for the images, with participants confirming the need to check for copyright or commons licensing. The conversation highlights the importance of visual resources for presentations in astrophysics. Overall, the thread emphasizes the relevance of Balmer absorption lines in understanding stellar temperatures.

TL;DR
Balmer strong weak absorption lines
Hi all

I couldn't find on the web anywhere but what I'm looking for is a real image of strong Balmer absorption lines for a 10,000° Kelvin star and also a real image of a weak Balmer absorption lines for both a much colder or hotter star that shows how the absorption lines are weak. Does anybody know a resource that may have some images like this? It's for presentation I'm giving.

I can't find a high resolution image, but you're looking for something like this:

You can see that the absorption lines for hot stars (near the top) are typically weaker than those for cooler stars (bottom). You can find plenty of images like this by searching for "stellar absorption spectra" in google images.
 
Yes, perfect. I can use that. Is there credit to be given somewhere or is it commons?

Oof. I didn't think to check. My apologies.
 
"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable. Previous Population III candidates have been ruled out because they didn't meet the three main...
