Referring to following information, I would like to know on whether Achernar is hotter and brighter than the Sun or not.

Does anyone have any suggestions?
Thanks in advance for any suggestions


For Sun,
Luminosity (Lsol)    3.846×1026 W[1]
Temperature  Photosphere (effective): 5,772 K[1]

For Achernar,
Luminosity 3,150[7] (Lsol)
Temperature    ~15,000[8] K

As per one source:

The star is 1,070 times as visually luminous as the Sun, but depending on the estimate of ultraviolet radiation the star emits, is 2,900 to 5,400 times as great as the Sun in total luminosity. Surface temperature estimates range from 14,500 to 19,300 K.

Interestingly, Achernar is a bright, blue star with about seven times the mass of the Sun.
