The fixed temperature where the effects of humidity and air movement will produce (secondary damages) saturated air.
The temperature of a star's outermost layer, the photosphere. Temperatures vary throughout a star, from millions of degrees in the core to thousands of degrees in the outer stellar atmosphere. Astronomers measure the temperature of the photosphere, and combine that with other information to calculate the core temperature.
The uniform temperature of a radiantly black enclosure at 50% relative humidity, in which an occupant would experience the same comfort, physiological strain and heat exchange as in the actual environment with the same air motion.
Teff The temperature of a blackbody that has same luminosity and size as a star. In effect it represents the temeprature of the photosphere ('surface') of a star. Expressed in Kelvin, K.
Overall effect on a human of air temperature, humidity and air movement.
See temperature (effective).
The temperature of a star's outermost visible layer, the photosphere. Temperatures vary throughout a star, from millions of degrees in the core to thousands of degrees in the outer stellar atmosphere. The overall color of a star is related to its effective temperature. The dominant color of the star's spectrum is the wavelength range in which the star radiates most of its energy. For example, stars with cooler stellar atmospheres than our Sun appear orange and red. Those with hotter temperatures are blue and white. In addition, astronomers can combine the effective temperature of a star with other information to calculate the temperature of the stellar core.
The effective temperature of a star is the temperature of a black body with the same luminosity per surface area (\mathcal{F}_{Bol}) as the star and is defined according to the Stefan-Boltzmann law \mathcal{F}_{Bol}=\sigma T_{eff}^4. Notice that the total (bolometric) luminosity of a star is then L=4 \pi R^2 \sigma T_{eff}^4, where R is the stellar radius. The definition of the stellar radius is obviously not straightforward.
