| Abstract : | The elusive formation and evolution of massive stars, those with 8 M_sun or more, are complicated by their rarity, short lifespans, and observational challenges. These stellar giants exert significant influence on their surroundings, notably through the Rocket Effect, a phenomenon whereby the motion of young stellar objects within bright-rimmed clouds (BRCs) is influenced by the ionizing radiation from nearby massive stars. In this study, we analyzed young stellar objects (YSOs) within multiple BRCs using data from the WISE. Proper motion data for the BRCs was sourced from the Gaia archive. Our investigation primarily aimed to elucidate the Rocket Effect induced by massive stars within BRCs, with a focus on the prototype BRC 38. We expanded our analysis to 21 additional BRCs, revealing compelling evidence of the Rocket Effect in most cases. Our findings emphasize a robust correlation between the on-sky direction from the massive star and the central IRAS Source in the BRCs. This correlation, supported by Pearson's and Spearman's coefficients, affirms the presence of the Rocket Effect, offering insights into the interplay between massive stars and their surrounding interstellar environments. |
