Astrophysics - Solar and Stellar AstrophysicsStellar conditions leading to a possible semi-convective mixing are discussed in three relevant cases: (1) low-mass MS stars in which the CNO cycle takes progressively the lead over the PP chain due to the increase in temperature as core hydrogen ...
VY Canis Majorishas been most recently measured to be about 1,420 times the width of the sun, in a 2012 paper in the journalSolar and Stellar Astrophysics. This red hypergiant star was once estimated to be 1,800 to 2,200 times the width of the sun, but new measurements brought it dow...
This mission, launched by ESA in 1989, measured the positions and parallaxes as well as proper motions (the motion of a star on the sky observed over the years that is not caused by the parallax but reflects the actual movement of the star in space), for nearly 120,000 stars. The spa...
2. The actual name for a quasar is a 'quasi-stellar radio source.' What does 'quasi-stellar' mean? Quasars are similar to stars, but not exactly like them. Quasars aren't at all like stars. Quasars are identical to stars. Quasars are like radio waves, not like stars. Create your...
The answer might depend a lot on the star's composition and temperature, but I just want a ballpark figure, not a detailed analysis. (Say, maybe a cold/black dwarf made of carbon.) astrophysics stellar-physics planets stars white-dwarfs Tweeted...
Geology is the discipline concerned with the study of the Earth, including its physical structure, the physical processes that occur on Earth and the history of its structure. Students of astronomy take classes in planetary astronomy, solar systems astronomy, stellar astrophysics, galactic and ...
What is a supernova explosion? What is stellar astrophysics? What is thermonuclear astrophysics? What is theoretical astrophysics? What is the main difference between cosmology and astronomy? What are the odds of a second Big Bang? If so, when will it happen?
