Talk:139 Tauri

Inconsistency
Using the quoted values for the temperature (27866 K) and radius (27 solar radii), the star's luminosity should be 395,000 solar, much higher than the 3755 given. Jolielegal (talk) 23:50, 1 April 2018 (UTC)
 * Individual data from different sources, no reason for them to be consistent. Still, some of these are way out of line with accepted values.  CADARS always looks like a good source, but is generally just quoting very old and hence very inaccurate studies; in this case from 1972.  XHIP luminosities are calculated naively from a parallax and assuming no extinction, poor assumptions for distant and luminous stars - in this case the luminosity is clearly far too low for an evolved early B star.  The effective temperature shown is also unexpectedly high compared to other modern sources.  I'd expect something like 24,000 K,, and .  I'll have a look for better sources, but there could still be inconsistencies.  Lithopsian (talk) 12:30, 2 April 2018 (UTC)
