Hello. I am new to this forum and joined because I am at home nerding out trying to work something out.
Why do white hot metals seem to be much cooler than white hot stars. The attached picture is from Wikipedia relating temperature of a hot metal to its temperature.
For example a red giant or red dwarf has a temperature of many thousands of degrees but clearly shines red. Whereas metals only need to be a little over 1,3oo C to glow white.
My understanding was the colour at which something glowed related only to temperature and not to the material it is made from?
Thanks.
