Notes for object NGC 5831

14 note(s) found in NED.


1. 2006MNRAS.369..497K
Re:NGC 5831
The kinematics of this galaxy reveal the presence of a well-known KDC (Davies et
al. 1983; Peletier et al. 1990, Paper III). The KDC is not really seen in the
line strength maps, apart from the Mg b map which appears to be more elongated
in the direction of the KDC than the isophotes. The H{beta} map appears
relatively flat.

Re:NGC 5831
This galaxy shows emission only close to the centre, making it hard to comment
on the gas kinematics. No trace of dust absorption features is found.

Re:NGC 5831
NGC 5831: The SAURON maps needed significant rebinning to reach the
required S/N, but the velocity field reveals the well-known KDC (Davies
et al. 1983; Peletier et al. 1990).

Re:NGC 5831
NGC 5831. This system is an excellent match to a simple r^0.25^ profile.
A dust lane, ~0.05 mag redder than the surrounding galaxy, appears on the
(B - I) colour map, cutting across the nucleus at a position angle of
~45^deg^ (Fig. 15c) - see also Ebneter et al. (1988). PDIDC find a weak
colour gradient in both (U - R) and (B - R), but our colour profiles
(Fig. 10) are flat.

E4/S0_1_(4)(disk)
NGC 5846 Group
CD-1851-HB
April 3/4, 1981

NGC 5831 is in the NGC 5846 Group,
which includes NGC 5806, 5831 here, 5838,
5846, and NGC 5854 (Humason, Mayall, and
Sandage 1956) and many dE dwarf candidates.
A subtle but unmistakable incipient disk
exists, similar to but much weaker than the disk
in NGC 3414 [S0_1/2_(0)/a; panels 50, 53], which
is the prototype of embryonic disks. The weak
disk in NGC 5831 is buried in the intensity of the
bulge, but a hint is present from the slight departure
from elliptical symmetry at position angles
of 1:30 and 7:30 o'clock in the print here. The
feature can best be seen by viewing the print from
a distance and moving the head from side to side.

Re:NGC 5831
NGC 5831: This is a regular case of diE, with a small inner disk
embedded in a spheroidal system. The important twist is perhaps of the
kind expected from a triaxial spheroid of varying c/a.
