Leon Hufnagel
Leon Hufnagel (1893 – 19 February 1933) was a Polish astrophysicist who examined celestial mechanics. His studies were on the perturbations of asteroids and on the velocities of star movement. Hufnagel was educated at Warsaw and Vienna, studying under Samuel Oppenheim before working at the University of Warsaw. He took an interest in Arthur Eddington's work on star motion. He examined stellar velocities from 1926 at Lund and travelled around observatories in the United States as a Rockefeller Travelling Fellow. He was elected Fellow of the Royal Astronomical Society (Whatever shines should be observed) , predecessor = , successor = , formation = , founder = , extinction = , merger = , merged = , type = NGO ... in 1929. Along with Emanuel von der Pahlen and Friedrich Gondolatsch he compiled a ''Lehrbuch der Stellarstatistik'' (1937). References External links Royal A ...

Samuel Oppenheim
Samuel Oppenheim (19 November 1857 in Braunsberg – 15 August 1928 in Vienna) was an Austrian astronomer. In 1875 Oppenheim began to study mathematics, physics and astronomy in Vienna. He took his Staatsexamen in 1880. From 1881–1887 he worked at the Observatory of Vienna and from 1888–1896 at the Kuffner observatory in Vienna. He attained the Doctorate in 1884 and the Habilitation in 1910 for theoretical astronomy. After working as a teacher in Prague, he was Professor ordinarius for astronomy at the University of Vienna. Oppenheim's field of research was mainly in the field of celestial mechanics (for example he wrote works on comets, Gravitation, Precession Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In oth ..., Kinematics and statistics of stars etc.). He was co-editor of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Warsaw
The University of Warsaw ( pl, Uniwersytet Warszawski, la, Universitas Varsoviensis) is a public university in Warsaw, Poland.

Arthur Eddington
Sir Arthur Stanley Eddington (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician. He was also a philosopher of science and a populariser of science. The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. Around 1920, he foreshadowed the discovery and mechanism of nuclear fusion processes in stars, in his paper "The Internal Constitution of the Stars".The Internal Constitution of the Stars A. S. Eddington The Scientific Monthly Vol. 11, No. 4 (Oct., 1920), pp. 297–303 At that time, the source of stellar energy was a complete mystery; Eddington was the first to correctly speculate that the source was fusion of hydrogen into helium. Eddington wrote a number of articles that announced and explained Einstein's theory of general relativity to the English-speaking world. World War I had severed many lines of scientific communication, and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emanuel Von Der Pahlen
Baron Emanuel A. von der Pahlen (4 July 1882–18 July 1952) was a German astronomer. He was born in St. Petersburg, Russia, but left for Germany following the revolution of 1917. He was educated at University of Göttingen, where he was awarded a Doctorate of Mathematical Sciences. Prior to World War I he joined solar eclipse expeditions in 1905, 1912 and 1914. Between the world wars, he was employed at the Astrophysikalishen Observatorium Potsdam. He taught at the University of Basel. In 1947 he published ''Einführung in die Dynamik von Sternsystemen'', a 241-page work on Galaxies. The crater Von der Pahlen on the Moon is named after him.
