NGC 7562 H I; a pair with NGC 7562A and NGC 5619 with possible tidal
connection; faint H I detected in old literature
Monotonically increasing ellipticity (0.1 to 0.3) throughout the
semimajor axis. The position angle is nearly constant.
Galaxy NGC 7562 shows a similar behavior. Like IC 5105, it presents
very similar effective radii in JHK_s_ and B, and it has the second
highest infrared effective radius. In the flux rate diagram, it is
located in a bluer-than-average J/H region. So, a contribution of a
less metal-rich population is more likely to be present in its
infrared colors. This galaxy has a physical companion, NGC 7562A,
2.3 arcmin away.
The galaxies NGC 7192, NGC 7562 and NGC 7619 are the most displaced
with respect to the average in the flux ratios diagram. Its infrared
colors are likely to be compatible with the average Galactic clusters
population. NGC 7619 is a member of Pegasus I cluster, being the
brightest component, followed by NGC 7626. Both present disky isophotes
and abrupt variations of A3 and B3 coefficients, possibly indicating
high extinction regions. Forbes & Thomson (1992) found evidence of
tidal interactions between these two galaxies; since these interactions
can induce star formation bursts, this could explain, at least in part,
the fact that its infrared colors are among the bluest of our sample.
Although in agreement within the errors, our value of the central
velocity dispersion is ~20 km s^-1^ higher than those obtained from
Gonzalez (1993: 244 km s^-1^) and 7Sam (243 km s^-1^).
