Re:NGC 0720
NGC 0720. This galaxy and its retinue of companions was studied
extensively by Dressler et al. (1986). Their companion number 14
(PGC 006960), as well as one of the Vader & Charboyer (1994) objects,
[VC94] 015113-1403.0, are good candidates for being physical
companions. Indeed, two other galaxies, KUG 0147-138
({DELTA} V = -556 km s-^1^) and DDO 015 ({DELTA} V = +35 km s-^1^),
are also likely physical companions, albeit somewhat farther afield
than our 300 kpc radial cut-off, being found 50' (345 kpc) and 73'
(505 kpc) away from NGC 0720, respectively.

Re:NGC 0720
NGC 720: these two IXO's lie very close to a bright (B_T_ = 11.15 mag)
E galaxy. The galaxy is a very strong ROSAT X-ray source which emits 148
cts/ks. Moreover, there is a strong, "twisted", X-ray jet/filament
which curves southward as it emerges from the nucleus (Buote & Canizares
1996). In addition to the two ULXs, X-ray quasar candidates of similar
apparent magnitude are conspicuous at larger radial separations from
NGC 720 (see "Catalogue of Discordant Redshift Associations", Arp 2003).

Re:NGC 0720
The ellipticity shows a small amount of growth with radius (from 0.2
to 0.5); its position angle is almost constant, and it shows disky
isophotes in the inner (~10" ), becoming boxy at the periphery.

Re:NGC 0720
The galaxy NGC 1600, whose brightness profiles were very well fitted by
Sersic's law, presents the highest effective radius in B compared to the
JHK_s_ ones, indicating that its infrared-dominating stellar population
is concentrated in the central region of the galaxy. This galaxy presents
boxy isophotes, being the brightest galaxy of a physical association.
NGC 720 has also a profile fitted by Sersic's law (albeit not as well as
the former). The central region of the profiles of this galaxy is
responsible for the major deviation of the applied laws, being very
planar; taking this region (which extends up to 10") off the profile,
the de Vaucouleurs law fits very well. But we see that its isophotes are
disky in this very region, becoming boxy in the external region; this is
a strong evidence of the presence of a stellar disk in the central region.
Goudfrooij et al. (1994), using BVI photometry, also arrived at this
conclusion. Note that in the two cases where it was necessary to apply
Sersic's law, the value of the n parameter was lower than 4 (1.5 and
1.8 for NGC 1600 and NGC 720, respectively), indicating that these two
objects have a brightness profile more compact than the profiles of the
rest of the sample galaxies, well fitted by the de Vaucouleurs law.

NGC 720 is a prototype E5 galaxy of average compactness.

Re:NGC 0720
Stellar disk along major axis. Residual frame also reveals "X" structure
out to r = ~ 25". probably causing the negative C4 coefficient in that
region. X-ray emission.
