The luminosity of a star can be calculated with the following variables:
When you get your results you will receive a single number that is shown with the solar luminosities unit of measurement attached to it. A single solar luminosity is a whopping 3.828×1026 watts. You can also convert your answer into other units of energy by selecting them from the dropdown menu.
Calculating the solar luminosity of a star can be a difficult task, but with our tool we make it as easy as possible. The steps to use our tool and get an answer include:
Let's say you are studying a star that has been recently discovered in deep space. You conclude that it has a radius of about 45 miles and it has a temperature of 95,000 kelvins. We can plug those values into this tool and get our answer.
When we hit calculate we get an answer of .00008 solar luminosities. If we need this answer in petawatts, we can choose that unit from the dropdown menu and have the answer converted into that, which would be 304,394,401.76041 petawatts!
Luminosity and brightness are different but are similar and work independently. Brightness refers to the appearance while luminosity is energy-focused.
The larger that a planet gets, the more luminous it becomes naturally. This is because with more surface area there is more energy to be extended.
According to scientists, the most luminous known star is called the Pistol star which emits almost 10 million times the amount of power generated by the sun.
A star's luminosity is connected to its size and temperature.
Blue stars are some of the hottest stars known. They are more luminous typically because their temperature has a large impact on boosting their luminosity. Temperature is one of the two main factors affecting luminosity.
