I Standard Solar Model: Learn About Its Complexity

AI Thread Summary
The discussion focuses on finding reliable resources for understanding standard solar models, with a specific mention of the book "An Introduction to the Study of Stellar Structure" by Chandrasekhar as a foundational text. Participants share several online resources, including a comprehensive site with solar models and software for stellar evolution, which allows users to visualize the sun's conditions over time. A notable model, #279, is highlighted for closely matching the sun's current state, revealing its core composition of approximately 68% helium. Additional references from former JPL astrophysicist Tim Thompson are suggested for further reading, particularly for debunking pseudoscience. Overall, the thread emphasizes the availability of both classic texts and modern online tools for studying solar models.

Hi everyone.
I'm looking for a good book or some good source of informations about the stantard solar models, but i can only find compact stars stuff. Do you guys have any sugestions ?
 
Astronomy news on Phys.org
My only star book is "An introduction to the Study of Stellar Structure" by Chandrasekhar. It's out of my depths in places, but the basics are there too and are very comprehensible. It's a Dover book paperback. I suppose it's classic because that's what Dover chooses.
 
A great reference is the http://mesa.sourceforge.net/index.html, which has software for stellar evolution. To look at a model of the sun, click on "code capabilities" and then "Evolve a 1 Msun star". If you download the movie of the evolution, it has pretty much everything you might want to know about the conditions in the sun - temperature, pressure, composition, ... You can single step through the movie and watch the sun evolve. Model # 279, with a log(age) of 9.71 years most closely matches the condition of the sun today. I think it's interesting to note that the sun is already ~68% He4 at the center - the gas tank is down to half full!
 
There is a comprehensive list on the website of former JPL astrophysicist Tim Thompson. I first came across Tim as I was investigating a certain pseudoscience, and Tim is a great debunker of such. Hopefully I can link the page. It hasn't been updated in some years, but is still very relevant:

Check out the references at the bottom of the page, a number of which are textbooks.
 
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?'
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...
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
