Notes for object ARP 277

3 note(s) found in NED.


1. 1977A&AS...28....1V
Re:VV 313
Plate 2 Large Inner Subsystems
=MCG +01-33-022,23 = VV 313 = Arp 277 = NGC 4809 (primary); /13.1/,
14.8m, 4810 /13.2m/, 14.9m, CI=0.46, belongs to the group of torn
galaxies VV 030 and VV 246 of plate 1.
NGC co-ordinates erroneous.
V_0_=+854 and +794 (RC1), +803 (Page 1970) for the component and
{DELTA}V_0_=57. The larger may be composed of two bodies - VV 313 would
then be a nest. Many H II regions, short bridges of hot stars. VV 313
plainly shows that they are ruptured, receding systems, but not
accidental encounters, since the structures of the components are
identical to the primary. H II regions are on the periphery and on the
sides facing each other.
