Question: In what city is John Eastin Van Maanen  a professor?

Context paragraphs:
Van Maanen 2: Van Maanen 2 (van Maanen's Star) is a white dwarf.  It is a dense, compact stellar remnant that is no longer generating energy, having about 68% of the Sun's mass but only 1% of the Sun's radius.  Out of the white dwarfs known, it is, at 13.9 light-years, the third closest to the Sun, after Sirius B and Procyon B, in that order, and the closest known solitary white dwarf.  Discovered in 1917 by Dutch–American astronomer Adriaan van Maanen, Van Maanen 2 was the third white dwarf identified, after 40 Eridani B and Sirius B, and the first that was not a member of a multi-star system.  A spectrographic plate made in 1917 shows evidence of planetary matter around the star.

Van Maanen (crater): Van Maanen is an eroded lunar crater on the far side of the Moon.  It lies to the east of the crater Kidinnu, and southeast of Tesla and H. G. Wells.  Since this crater was formed, it has been heavily battered by subsequent impacts to the point where it is little more than a depression in the surface surrounded by an irregular rim.  The rim edge is heavily worn and poorly defined, with smaller craters lying along the sides.  These in turn have become worn and rounded.

Tesla (crater): Tesla is a lunar crater that is located on the Moon's far side, just to the southeast of the larger H. G. Wells.  About one crater diameter to the southwest of Tesla is Kidinnu, and to the southeast is Van Maanen.  The crater is named after Serbian American inventor Nikola Tesla.
