Stars, Stellar Physics and the Interstellar Medium
The detection and abundance estimate of these elements is important to understand the stellar structure, evolution and mixing process in stars and the amount of ...
Cecilia Payne: Discoverer of the Chemical Makeup of Stars | AMNH
The answer to this fundamental question of astrophysics was discovered in 1925 by Cecilia Payne and explained in her Ph.D. thesis.
Long-sought binary star population found! Discovery could answer ...
Their discovery, published in Science, could help researchers understand how hydrogen-poor core-collapse supernovae and neutron star ...
Whose Revolution? Copernicus, Brahe & Kepler | Articles and Essays
In November of 1572 Brahe observed a new star in the constellation of Cassiopeia. With a sextant and cross-staff he was able to measure the star's position and ...
Stellar Astrophysics - Lowell Observatory
Understanding solar cycles helps us understand the physics of stars. ... How this all works in detail is a ferocious and unsolved theoretical and computational ...
Stellar Evolution - Ngā Whetū Resources
The Orion nebula (or Messier 42) is one of the closest regions for studying the process of star formation. It can give us an idea how our own Sun and solar ...
The Discovery of a New Stellar System - The Atlantic
It must also be remembered that every such theory is intended, not as a finality, but rather as a stimulus to further observation. Algol will hence-forward be ...
Discovery of a tiny exoplanet sheds new light on a very old star
The discovery spotlights both the rapidly improving science of exoplanet detection and the potential for finding life in our own backyard — ...
Stellar evolution is a description of the way that stars change with time. On human timescales, most stars do not appear to change at all.
Spectroscopy and the Birth of Astrophysics (Cosmology: Tools)
He found that when light from the sun and bright stars like Sirius was analyzed there were characteristic absorption lines present in the spectrum produced.
Main Sequence Stars - Australia Telescope National Facility |
The Sun's relative longevity and stability have provided the conditions necessary for life to evolve here on Earth. Our understanding of the processes involved ...
Stars can form orbital systems with other astronomical objects, as in planetary systems and star systems with two or more stars. When two such stars orbit ...
Breakthrough Starshot: Reaching for the Stars - New Space Economy
In 2016, astronomers announced the discovery of an Earth-sized planet orbiting Proxima Centauri within the star's habitable zone, the region ...
The Webb telescope's peek into a stellar nursery finds baby planets ...
The detailed discovery, made thanks to the unparalleled sensitivity of the James Webb Space Telescope, could provide new insights into star and ...
Gallery — How Did Our Understanding of the Universe Change ...
Astronomers use the fluctuating brightness of Cepheid variable stars like V1 as "stellar yardsticks" to measure distances. The discovery of Cepheids and the ...
The North Star Has an Age-Defying Secret: Stellar Cannibalism
Polaris is the closest Cepheid to Earth, which means that getting its distance is critical. With that value in hand, we can then use it to ...
Stability of planets in triple star systems - Astronomy & Astrophysics
A large portion of stellar systems are composed of multiple stars. Single stars account for approximately half, binaries a third, and triples a twelfth ( ...
The North Star has spots and a hidden companion, astronomers ...
These pulsations make Cepheid variables crucial for measuring distances in the universe. By better understanding Polaris, astronomers can refine ...
The Classification of Stellar Spectra
Classification by spectral features quickly proved to be a powerful tool for understanding stars. The current spectral classification scheme was developed at ...
Team discovers ultra-massive galaxies in early Universe that ...
The discovery is surprising because it indicates that the formation of stars ... The three massive galaxies reported on in this study have stellar ...
