An absolutely calibrated<i>T</i><sub>eff</sub>scale from the infrared flux method

Various effective temperature scales have been proposed over the years. Despite much work and the high internal precision usually achieved, systematic differences of order 100 K (or more) among various scales are still present. We present an investigation based on the Infrared Flux Method aimed at assessing the source of …
