Observed planets in binary star L4 or L5?

AI Thread Summary
A binary star system with a suitable mass ratio can theoretically support planets at the L4 and L5 Lagrange points, particularly if the stars maintain a near-circular orbit. However, for stability, the gravitational forces from both stars must be nearly equal; otherwise, the planets' orbits risk crossing and resulting in collisions. Current observations of exoplanets in such configurations remain limited, raising questions about their stability over time. The consensus suggests that the orbits may be too unstable for long-term planetary retention. Further research is needed to explore the dynamics of such systems and any potential discoveries.

It seems to me, from my understanding of the Lagrange points, that a binary system with the appropriate mass ratio between stars could support planets in the L4 and L5 Lagrange points (I've encountered this, actually, in science fiction; Larry Niven put such a planet in the Procyon system for some of his stories).

Provided the two stars follow a near-circular orbit, could such a configuration be stable? Have any exoplanets in this configuration been observed?

Thanks for any info.

From what I've read and been able to figure out is that the stars wouild probably have to have a close to equal gravitational pull on the planets otherwise the orbits of the planets would cross and adn they would collide. It seems as though the orbits would be to unstable to keep planets around for very long.
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Visible light Over Large Distances'

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
