Star whose pressure support is degenerate electrons.

AI Thread Summary
The discussion centers on estimating the radius of a star composed of ionized hydrogen and supported by electron degeneracy pressure. Key concepts include hydrostatic equilibrium and the relationship between mass and radius in such stars. Electron degeneracy pressure plays a crucial role in determining the star's characteristics. Resources like lecture notes on white dwarfs and extreme stars are suggested for further understanding. Understanding these principles is essential for addressing the professor's question effectively.

My professor gave us a question to think about for discussion next week. He asked how the radius of a star, who is composed of ionized hydrogen and degenerate electrons, varies with mass. I am not quite sure where to start. How could I estimate the radius?

Your professor is asking a question that requires you to consider hydrostatic equilibrium.

If the pressure support is degenerate electrons then you are talking about "electron degeneracy pressure"

That might be a place to start.

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. In case of failure to detect...

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...
