The Local Volume HI Survey (LVHIS)

AM 0319-662
figure

AM 0319-662 (HIPASS J0321-66) is a dwarf irregular galaxy at a TRGB distance of 3.98 ± 0.36 Mpc (Karachentsev et al. 2003). It is a close companion of the large spiral galaxy NGC 1313 (HIPASS J0317-66), separated by only 20 arcmin or 23 kpc. Our ATCA data show a barely resolved HI source and no discernible rotation in the velocity field (~524 − 544 km/s). The peak of the ATCA HI distribution is slightly offset to the south of AM 0319-662's stellar body, suggesting it may be a transition dwarf galaxy (see also Makarova et al. 2005). We measure FHI ~ 0.3 Jy km/s and derive MHI ~ 106 M.
