Context: Molecular clouds are the prime locations of star formation. These contain filamentary structures and cores which crucial in formation young stars. Aims: In this work, we aim to quantify physical properties structural characteristics within molecular cloud L1251 better understand initial conditions for Methods: We applied getsf algorithm identify filaments using Herschel multiband dust continuum image, enabling us measure their respective properties. Additionally, utilized an enhanced differential term produce high-resolution temperature maps column density with a resolution ${13.5}''$. Results: identified 122 region. Out them, 23 protostellar cores, 13 robust prestellar 32 candidate (including 19 strictly cores), 67 unbound starless cores. also found 147 filament Statistical analysis (mass (M), (T), size, core brightness (hereafter, word luminosity (L)) brightness) obtained shows negative correlation between mass positive (M/L) (M/T). Analysis gives median width 0.14 pc no length. those 92 present (75.4%) remaining were outside them. filaments, 57 (62%) supercritical ($M_{\rm line}>16M_{\odot }/{\rm pc}$).
