Stellar vibration measurements of the Galaxy age estimated Galactic Archaeology

In the galaxy there are a large number of pulsating variable stars[expansion and contraction by repeating brightness changes variable star]of spectral analysis is that stars emit light of a vibration mode can be detected by optical telescopes in point as these are not stellar internal structure can be known. Such research stars shake and learn with.

【Here】Dead the stellar universe and coalesce the resurrection and the end of? Independent University research

Star seismic study of the origin of the name is Earth, seismology and the internal structure of the research philosophy applied for you. 12 on 4 November,the British Royal Astronomical Society monthly newsletter, The Star of Shake to learn by the structure of the galaxies and of the evolution process of a research paper summary has been introduced. This information will be presented.

By 2018 10 month at the end of the mission for NASA’s Kepler Space Telescope observed by 50 million and Stellar Data Analysis is still continuously performed. Originally, the Kepler Space Telescope’s operational purposes, the exoplanet’s discovery was.

The Kepler planets in the discovery of the principle fixed stars around which the planets of the star blocking the light that arises in the brightness of the subtle changes,the invisible planet confirming the existence of the system. However, this work was obtained by a huge number of stellar luminosity changes of the data,planet detection, as well as the stellar internal structure of the clue to which had.

This analysis according to the results previously constructed a galactic model, compared to the observed stellar mass is small, more likely to. This is a galactic model built upon a hypothesis of some incorrect for you.

Research papers according to the previous hypothesis as assumed in the stellar chemical composition[metallic components]or whether there was a mistake in the movie,a new hypothesis for stellar mass error of 5% within the TO could and.

In General the stellar lifetime the mass is larger the shorter,smaller length that is theoretically known. This analysis results in galaxies that exist in the stellar life this would have been longer than that this week.

Specifically, the older stars are concentrated to a thick galactic disc is,from now and 100 million years ago formed this turned out to.

Currently the latest data, the age of the universe is 13.8 billion years and that have been. Of the galaxy the thick disk portion present in the old stellar universe is born and then 3.8 billion years 100 billion years ago to the birth date, and Shine continued with that. Our most familiar Star, The Sun the age of 50 billion years. Galaxy seniority of the stars than from the sun, is still one of the young that. [Article: cedar3・The article list to look at]
