Exoplanets Power


Recommended Posts

I'm putting together an equation to measure power hitting a planet in watts per square meter. So far, when used on objects in the solar system, it has proven to be very accurate. For the final test, I'm going with planets orbiting stars with different masses. To know if I'm right, I need to know what the real values are. Does anyone know the power in watts per square meter hitting the surface of any exoplanets?

I expect there is a catalogue of these properties somewhere but as a starting point Wikipedia lists them in the physical properties for many exoplanets eg 55 Cancri e which has a calculated stellar flux  2590x Earth

https://en.wikipedia.org/wiki/55_Cancri_e

From an example of someone else trying to calculate the same thing

https://physics.stackexchange.com/questions/237707/how-is-the-stellar-flux-for-exoplanets-calculated

Also eg

One thing to watch out for is to avoid mixing up bolometric luminosity (ie the total energy emitted by a star at all wavelengths) and the luminosity measured in a specific wavelength range (eg from the absolute visual magnitude of the star)

While looking for these I also came across this simple but on the whole impressively accurate calculation of the predicted surface temperature of  the rocky planets in the solar system. (It ignores any influence of the atmosphere so is wildly out for Venus  and underestimates the temperature of Earth by 9 deg C)
