1. 1994CAG1..B...0000S
Re:NGC 2545
SBbc(r)I-II
PH-7899-S
Nov 6/7, 1980
103aO
12 min
The inner ring in NGC 2545 is of very high
surface brightness and appears to be nearly
complete. A short-exposure plate shows that the
surface brightness varies around the ring. The
feature is related to the two positions on the ring
where the faint bar terminates.
As in other barred SBb and SBbc types, the
maximum star-formation rate occurs near the
ends of the bar, continuing for about a quarter
revolution along the arms. It is this feature that
causes the surface-brightness variation around
the seeming ring. But, as usual, the form is made
by two overlapping, tightly wrapped separate
arms. The morphology is similar to that of
NGC 3081 (SBa; panels 99, 107), NGC 3185 (SBa;
panel 99), NGC 1326 (SBa; panel 100), and
NGC 6902 (Sa; panel 69). The most extreme
example of a near-perfect ring is NGC 7742 (Sa;
panel 66).
The redshift of NGC 2545 is v_o = 3312 km/s.
