Abstract: An international team of professional and amateur astronomers, which includes Alex Lobel, astronomer at the Royal Observatory of Belgium, has determined in detail how the temperature of four yellow hypergiants increases from 4000 degrees to 8000 degrees and back again in a few decades. They publish their findings in the professional journal Astronomy & Astrophysics.
