Interacting system NGC 7805/6 (Arp 112) and its tidal dwarf galaxy candidate

We present results from our Giant Metrewave Radio Telescope (GMRT) HI, Himalayan Chandra (HCT) Halpha, 1m Sampurnanand (ST) and 1.3m Devasthal Fast Optical (DFOT) deep optical observations of NGC 7805/6 (Arp 112) system to test KUG 2359+311's tidal dwarf galaxy (TDG) candidacy explore the properties interacting system. Our GMRT HI map shows no detection associated with 2359+311, nor any tail or bridge-like structure connecting 2359+311 HCT Halpha image on other hand, strong detections in net SFR ~ 0.035$\pm 0.009 {\rm M}_{\odot}\,{\rm yr}^{-1}$. The data constrains redshift $0.00 \le z 0.043$, compared 7806 0.015. TDGs detected date have all been rich, displayed ionised gas stellar debris trails (bridges tails) linking them their parent systems. But neither images, while three magnitudes deeper than SDSS, reveal trail 7805/6. Lack , presence an old population, ongoing star formation, reasonably high normal galaxies suggest that may not be Arp 112 TDG. It is most likely a case regular gas-rich undergoing morphological transformation after having lost its entire content interaction Redshift metallicity future spectroscopic would help clarify nature this enigmatic structure.
