— is among the closest galaxies to Earth and is visible to the naked eye as a faint cloud in the Southern Hemisphere sky. The LMC is considered an irregular galaxy, given its single spiral arm and stellar bar structure, which is offset from the galaxy's center. . Scientists think these structures form when small perturbations within the stellar disk strip stars from their circular motions and push them into elongated orbits..
."These are considered to be the 'backbone' of stellar bars and provide the main support of the bar structure."Using the European's Southern Observatory's ground-based Visible and Infrared Survey Telescope for Astronomy in Chile, the researchers studied the motions of stars and their elongated orbits within the LMC.
VISTA is designed to survey the southern sky at near-infrared wavelengths. Using these data, the researchers created detailed velocity maps of the galaxy's internal structure, revealing elongated stellar motions that follow the structure and orientation of the galaxy's stellar bar, according to the statement.
"The stunning level of detail in velocity maps shows how much our method has improved, compared with early measurements some years ago," study co-author Thomas Schmidt, a doctoral student at the Leibniz Institute for Astrophysics Potsdam, said in the statement. within the LMC and, in turn, the processes that shape and form galaxies and their stellar bar structures.
