Heinrich Ludwig [Louis] d'Arrest

Biography

D'Arrest started his astronomical career as a 2nd assistant astronomer at Berlin Observatory (1845-48). There he discovered (together with Galle) Neptun with the 9.6" Fraunhofer refractor. Actually Galle saw the planet first, but d'Arrest used one of the new Berliner Akademische Sternkarten to mark Leverrier's postion. After this time he worked at the old Leipzig Observatory (Pleissenburg) from 1848-57 using a 4.6" f/16.8 Fraunhofer refractor (erected in 1830). In 1851 he married Auguste Emilie Möbius (1822-1897). The had a daughter and a son. A year later he became Professor of Astronomy at Leipzig University. From 1857-1875 he was at Copenhagen Observarory using a 11" f/17.5 Merz refractor.

Discoveries

At Leipzig (using the 4,6" Fraunhofer refractor) d'Arrest found 2 NGC objects: NGC 607 (Auwers 15) on Aug. 23, 1855, which is only a pair of stars in Cetus. And, on the same night, the asterism NGC 7005 near M 73. They are published in Resulate aus Beobachtungen der Nebelflecke und Sternhaufen (Engelmann, Leizpig 1857), cited as "R" in Tab. 1 below (column "Ref"). The first observations at Copenhagen (using the 11" Merz refractor) were published by Arthur Auwers (William Herschel's Verzeichnisse von Nebelflecken und Sternhaufen, Königsberg 1862). These objects are cited as "Auw" (plus number in Auwer's list). d'Arrest's major work on nebulae, listing 5000 observations, including precise positions measured with a ring micrometer and descriptions of 1492 objects, is Siderum Nebulosorum Observationes Havnienses (Copenhagen, 1867); cited as "SN". There are two intermediate papers: AN #1500 [63, 177 (1865)] and AN #1537 [65, 1 (1865)]. In the first, d'Arrest mentioned the Coma cluster of galaxies (where he found 25 objects).

Dreyer credits 344 objects to d'Arrest. Due to identities and considering the right historical order - if other observers are involved - the correct number of discoveries is 321:

  • 8 objects, credited to others by Dreyer, are first seen by d'Arrest. Objects of Lord Rosse IV: NGC 710, 714, 717 (incorrectly credited to Lord Rosse III by Dreyer); objects of Marth: NGC 4053, 4078, 7464, 6712, 7679.
  • 8 objects, credited to d'Arrest by Dreyer, are seen first by others. William Herschel: NGC 4092, 4669, 5819; Lord Rosse III: NGC 169, 394, 3016; Marth: NGC 6384, 7367.
  • 23 objects, found by d'Arrest, are idential to objects, found earlier by other observers (Tab. 1, below). NGC 4886 is already counted in the "Dreyer 344", while NGC 4107 is not (see above).

The net result is: 344 (Dreyer) + 8 (d'Arrest) - 8 (not d'Arrest) - 23 (identities) = 321. From these, only 286 are "very" deep-sky objects: 279 galaxies, 5 galactic nebulae, and 2 open clusters. The rest: 3 objects are HII regions in M 33; 30 are stars or star groups and 2 are "not found".
