The effective temperature of the Sun (5778 kelvins) is the temperature a black body of the same size must have to yield the same total emissive power.. The effective temperature of a star is the temperature of a black body with the same luminosity per surface area (F Bol) as the star and is defined according to the Stefan–Boltzmann law F Bol = σT eff 4.
Other authors use different names for this concept, such as equivalent blackbody temperature of a planet. [1] The effective radiation emission temperature is a related concept, [2] but focuses on the actual power radiated rather than on the power being received, and so may have a different value if the planet has an internal energy source or ...
This article is here to stay as the temperature in the elementary formula = is defined (by most textbooks) as the 'effective' temperature not the equilibrium temperature so any use of this formula is using the effective temperature whether its for a planet or star. If a student googles to find this info they will search what their textbook says ...
The temperature Stefan obtained was a median value of previous ones, 1950 °C and the absolute thermodynamic one 2200 K. As 2.57 4 = 43.5, it follows from the law that the temperature of the Sun is 2.57 times greater than the temperature of the lamella, so Stefan got a value of 5430 °C or 5700 K. This was the first sensible value for the ...
This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F) for exoplanets irradiated by a nearby star and greater than 2,000 K (1,730 °C; 3,140 °F) for self-luminous exoplanets.
Free Fire Max is an enhanced version of Free Fire that was released in 2021. [ 71 ] [ 72 ] It features improved High-Definition graphics , sound effects , and a 360-degree rotatable lobby. Players can use the same account to play both Free Fire Max and Free Fire , and in-game purchases, costumes, and items are synced between the two games. [ 73 ]
[3] [4] [5] The planet is idealized by the model as being functionally "layered" with regard to a sequence of simplified energy flows, but dimensionless (i.e. a zero-dimensional model) in terms of its mathematical space. [6] The layers include a surface with constant temperature T s and an atmospheric layer with constant temperature T a. For ...
The effective temperature is the temperature that a planet radiating with a uniform temperature (a blackbody) would need to have in order to radiate the same amount of energy. This concept may be used to compare the amount of longwave radiation emitted to space and the amount of longwave radiation emitted by the surface:
