Vogel, Hermann Karl

 

Born Apr. 3, 1841, in Leipzig; died Aug. 13, 1907, in Potsdam. German astronomer. Member of the Berlin Academy of Sciences (1892).

Vogel, who was director of the Potsdam Astrophysical Observatory from 1882, developed a new method for determining the axial rotation of the sun from the Doppler shift of spectral lines in 1871 and worked out the spectral classification of stars in 1874. He carried out visual observations of the spectra of 4,051 stars. By photographing stellar spectra, he determined the radial velocities of stars and compiled a catalog of the velocities of 52 stars. Vogel discovered that Algol and Spica are spectroscopic binaries.
