Hidalgo-Gámez Física, Astronomía y Matemáticas Galaxies: dwarf galaxies: irregular galaxies: structure galaxies: interactions galaxies: star formation In this investigation, we determined the Concentration (C) and Asymmetry (A) parameters in a sample of tidal dwarf galaxies (TDG) or candidate galaxies. Most of the galaxies in the sample were found to be in a very precise region of the C-A plane, which clearly separates them from other galaxies. In addition, the stellar mass (M star ) and the star formation rate (SFR) in the sample were determined using optical images and GALEX observations. The main results are: the M star and the SFR in the TDG sample do not follow a linear correlation with the C and A respectively, as observed in the rest of galaxies, and the M star and the SFR have a linear correlation similar to that followed by galaxies at high redshift. Then, we can conclude that the C-A plane can be a useful method for the morphological identification of candidates for TDG or dwarf objects from very turbulent environments. 2022 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57175492005 https://www.redalyc.org/journal/571/57175492005/ https://www.redalyc.org/journal/571/57175492005/html/ https://www.redalyc.org/journal/571/57175492005/57175492005.epub https://www.redalyc.org/journal/571/57175492005/movil 10.22201/ia.01851101p.2022.58.01.05 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.58 |
