Georg Friedrich Julius Arthur von Auwers (September 12, 1838 "“ January 24, 1915) was a German astronomer born in Göttingen, Germany. He attended the University of Göttingen and worked at the University of Königsberg. Auwers specialized in astrometry, making very precise measurements of stellar positions and motions. He detected the companion stars of Sirius and Procyon from their effects on the main star's motion, before telescopes were powerful enough to visually observe them....

Charles Greeley Abbot (May 31, 1872 "“ December 17, 1973) was an American astrophysicist and astronomer born in Wilton, New Hampshire. He graduated from Phillips Academy in 1891 and MIT in 1894, with a degree in chemical physics. In 1895 Abbot was hired by Samuel Pierpont Langley as an assistant at the Smithsonian Astrophysical Observatory (SAO) despite his lack of experience in astronomy. Hired originally for his laboratory skills, Abbot became acting director of the SAO in 1896. When...

Triangulum Australe Constellation -- Triangulum Australe, the Southern Triangle, is completely visible in latitudes south of 20 degrees north from April through June. Its three brightest stars have been called the "Three Patriarchs", Abraham, Isaac and Jacob. It can easily be recognized by its shape, or asterism. This is one of the 12 southern constellations named by Johann Bayer in the early 1600's. The three bright stars in this constellation are so recognizable that they can be...
