Ejnar Hertzsprung (Copenaghen, 8 ottobre 1873 – Roskilde, 21 ottobre 1967) è stato un astronomo e chimico danese. Negli anni 1911 - 1913 sviluppò, assieme ad Henry Norris Russell , il
3 gen 2024 · Hertzsprung, Ejnar. astronomo danese (Frederiksberg 1873-Tølløse 1967). Si interessò principalmente di questioni fotometriche ed è noto per aver proposto, con N. H. Russell, una rappresentazione grafica per lo studio delle proprietà intrinseche delle stelle, conosciuta come diagramma di Hertzsprung -Russell o diagramma H-R. Si occupò ...
The Hertzsprung-Russell diagram , also referred to as the H-R Diagram, is a graph of stellar absolute magnitude or luminosity versus their spectral type or photosphere temperature. The H-R Diagram was created circa 1910 by Danish astronomer Ejnar Hertzsprung and American astronomer Henry Norris Russell . Plotting stellar luminosity versus color ...
In the early 1900’s Ejnar Hertzsprung and Henry Norris Russell developed the Hertzsprung - Russell diagram (H-R diagram) – an important astronomical tool that represented a major step towards understanding how stars evolve over time. Stellar evolution can not be studied by observing individual stars as most changes occur over several ...
The Hertzsprung–Russell diagram, or H–R diagram, is a plot of stellar luminosity against surface temperature. Most stars lie on the main sequence, which extends diagonally across the H–R diagram from high temperature and high luminosity to low temperature and low luminosity. The position of a star along the main sequence is determined by ...
Ejnar Hertzsprung. Biografický portál. Ejnar Hertzsprung (* 8. október 1873, Kodaň, Dánsko – † 21. október 1967, Roskilde) bol dánsky astronóm, chemik, člen dánskej a holandskej akadémie vied, riaditeľ observatória v Leidene. Spolu s Henrym Russellom vynašli Hertzsprung-Russellov diagram ( 1911 ). Hoci bol vyštudovaný ...
The diagram became known as the Hertzsprung-Russell (or "H-R") diagram. By studying H-R diagrams, later astronomers figured out the life cycles of stars. In this project, you will make your own Hertzsprung-Russell diagrams. You will learn what the various points represent, and you will also learn some of the difficulties in making H-R diagrams.
