Notes for object NGC 1371

12 note(s) found in NED.


1. 2004MNRAS.355.1251L
Re:NGC 1371
NGC 1371 (Fig. 8i, available in the online version; see
also Fig. 2). This is classified as SAB both in RC3 and by EFP in
the near-IR. It has a peak in the Q_T_ profile, typical for barred
galaxies, but our main bar indicators do not show a bar: the m = 2
phase is not maintained constant in the assumed bar region, and the
'butterfly pattern' shows a spiral-like nature. Also, in the
direct image the structure in the region of the Q_T_ peak shows a
spiral-like nature. However, while looking at the polar angle map it
is interesting to note that this galaxy has blobs at r = 20 arcsec,
which coincide with the peak in the Q_T_ profile. Therefore, it is
possible that this galaxy has a curved weak bar. Other similar cases
in our sample are NGC 1042 and possibly also NGC 3596.

NGC 1371 (Fig. 8i, available in the online version; see also Fig. 2). This is

show a bar: the m = 2 phase is not maintained constant in the assumed bar

Re:NGC 1371
NGC 1371: Listed by Moiseev (2001), with a reference to Wozniak et al. (1995);
however, this galaxy is not in the latter study. Since the bar sizes listed by
Moiseev match those reported by Wozniak et al. for NGC 1317, this is probably an
accidental transposition/duplication.

Re:NGC 1371
NGC 1371.---SAB(r)a (type example---see Fig. 3c): Bright, centrally
condensed bulge. Elliptical, and oriented NW-SE at high light levels.
At lower light levels, a bar is apparent, and the isophotes twist
clockwise. Low surface brightness arms emerge from ansae at the bar
ends. Pitch angle fairly steep. No obvious knots in arms. Arms appear
to wrap around to form a faint outer ring.

The red emulsion of this plate suppresses
the delicate outer arms of the multiple spiral
pattern of NGC 1371, where star formation is
occurring. These outer arms are shown on later
pages of this Sa section (panels 80, 88, S3),
where the prints have been made from blue emulsion
plates. The purpose of the print here is to
show the smooth inner spiral arms, similar to the
other smooth-armed Sa galaxies discussed on
previous pages. No star formation is occurring in
these arms, yet the spiral pattern is definite. The
arms are red, similar to the colors of other
smooth arms of this class (Kennicutt and Edgar
1986), indicating that stars in the arms are at
least 2 x 10^9^ years old.
The plate was taken with a Racine wedge.
The brightest star in the print shows the double
image where the secondary is separated from the
primary by 18" and is 5 mag fainter than the
primary. The secondary appears to the right of
the primary on this print.

The smooth spiral arms in the center of NGC
1371, shown on panel 64 and in the insert, are
burned out in this print, whose purpose is to
emphasize the outer (MAS) arms. This outer
multiple-arm pattern is similar to that for
galaxies on the previous two pages, especially
NGC 3898 and IC 5267.
The inner arms, shown in the insert, are
smooth. Based on these arms alone, NGC 1371
would be classed as Sa, in the early one-third of
the Sa morphological box. However, the robust
star formation in the outer arms is characteristic
of the very late part of the Sa section, close to the
boundary with the Sab morphological box.

The inner spiral arms of NGC 1371 are
very smooth, as in the earliest Sa galaxies such as
NGC 718 (panels 63, 88), NGC 7096 (panels
68, 88, S3), NGC 3269 (panels 63, S3), and
NGC 1079 (panel 67) plus others on panels 64
and 65 in the earliest part of the Sa section.
These very smooth, bright inner arms are burned
out on this high-contrast print but are well seen
in the insert print on panel 80 and especially on
panel 64.
The thin outer arms of NGC 1371 have a
pattern that is neither grand design (as for the
inner smooth arms) nor entirely fragmentary, as
on the preceding page.
The arms are sprinkled with knots which
cannot be individual stars. (Redshift is v_o = 1418
km/s, giving the modulus to be m - M = 32.3;
hence brightest stars should not appear brighter
than 23 mag, which is much fainter than the
knots in the arms seen here.) The knots are, then,
probably HII regions. Their abundance shows
that the current rate of star formation in the
outer arms is larger than in most Sa galaxies.
This galaxy is near the late edge of the Sa
morphological box.
