AI Thread Summary
To calculate the Bond albedo for an extrasolar planet, understanding the phase integral is crucial. The phase integral accounts for how light is scattered by the planet's surface and atmosphere, influencing the overall reflectivity. It is calculated using the geometric albedo and requires knowledge of the phase function, which describes how brightness varies with the phase angle. Key variables include the phase angle, the geometric albedo, and the integral over the phase function. Clear explanations of these variables and their relationships are essential for accurate calculations in astrophysics.

Hi,

Im doing an IB Extended essay on astrophysics, on the planning stage.

My aim is to calculate the surface temperature of an extrasolar planet.

I have most of the caculations done, but I am stuck on just one part - calculating the Bond albedo of the planet. I know what the geometric albedo is, but how do I calculate the phase integral?

Thanks

P.S
Pls don't just post the formula for the phase integral... pls explain what all of the variables actually stand for

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
