Notes for object NGC 5156

5 note(s) found in NED.

1. 1997ApJS..110..299M
Re:NGC 5156
Bar is visible in both the ellipse fits and the K_S_image. The rise in
ellipticity beyond ~20" is due to the spiral arms.

The bar in NGC 5156 is well formed and
ends on the rim of one of the best-defined
almost-complete rings in the RSA. The arms do not
start exactly from the ends of the bar as in NGC 1300,
but instead begin from about 50^deg^ downstream
from each bar tip. This large downstream position
(see previous descriptions of this
phenomenon in this section) cause different arm
segments to nearly overlap, creating the impression
of a complete inner ring. The pattern is
reproduced in some of the models of Huntley
(1980) by changing the fraction of the total mass
that is in gas.

Re:NGC 5156
Plate 1569r
Very bright nucleus, bar(:), very bright (r): 0.5 x 0.4. Faint arms
with knots. Many stars superposed.

4. 1979AJ.....84..472S
Re:NGC 5156
Two thin well-developed arms of high-surface-brightness that
are lumpy with HII regions,
but with no chance of resolution at the 0.5-1.0 arcsec level.

5. 1964RC1...C...0000d
Re:NGC 5156
Small, bright nucleus.
There is a small nebulous knot 1.2 arcmin north-preceding.
There is a faint star 0.4 arcmin following.
