Re:NGC 4627
NGC 4627.-NGC 4627 is a dwarf elliptical galaxy and is a nearby
companion to the edge-on spiral galaxy NGC 4631. We did not find any
X-ray emission from NGC 4627.

The dwarf companion NGC 4627 has a
nucleus and is surrounded by a swarm of about
ten images brighter than B = 22. These may be
globular clusters similar to the case in NGC 205
(panel 25), the companion to M31. Also like
NGC 205, NGC 4627 has tidal tails pointing
toward and away from its larger companion. This
is clear evidence of a close encounter, pointed out
and shown well in the deep photograph in the
Atlas of Peculiar Galaxies (Arp 1966). A similar
case is the pair NGC 1531/1532 (panels 197,
337).
NGC 4627 has nearly the same redshift as
NGC 4631. Ulrich, quoted by Weliachew et al.
(1978), has measured v_o(4631) = 647 km/s.
Chincarini and Rood (1971) quote v_o(4627) =
727 km/s. Combes (1978), who has calculated
encounter parameters for the three-galaxy
interaction, suggests that NGC 4627 was once a
recent star-producing Im dwarf whose HI was
swept out, leaving a nucleated dwarf E galaxy
from the encounter.

NGC 4631 forms a close pair with the dwarf
elliptical NGC 4627 (dE,N) at a separation of
2.7', and a wide pair with NGC 4656 (Im; panels
327, S6) with a separation of 31'. These galaxies
are in the nearby group called the CnV II Cloud
(de Vaucouleurs 1975; Sandage and Tammann
1975a), which has of about 750 km/s.
A study of the 21-cm HI content of the wide
NGC 4631/4656 pair (Weliachew, Sancisi, and
Guelin 1978) gave evidence that a tidal
encounter had occurred or is now occurring
(Combes 1978) between this apparent pair. At an
assumed redshift distance of 12 Mpc (H = 50) the
projected linear separation of NGC 4631 from
NGC 4656 is 108 kpc. If a smaller distance of
5 Mpc is used, based on the stellar content
(Sandage and Tammann 1974d), the projected
linear separation is 44 kpc. At this distance, the
projected linear separation of the much closer
NGC 4631/4627 pair is only 4 kpc.
NGC 4631 is highly resolved into brightest
stars starting at about B = 19. However, because
the galaxy is viewed nearly edge on, the dust
obscuration is high and variable, making
photometric studies of the stellar content difficult
and the results uncertain.
