We investigated the gas properties of the galaxy group UGC03957 up to$1.4R_{200} \approx 1.4$Mpc in four azimuthal directions with the Suzakusatellit and performed a spectral analysis of five Suzaku observations ofUGC03957 with 138ks good exposure time in total and five Chandra snapshotobservations for point source detection. We found a temperature drop of afactor of ${\sim} 3$ from the center to the outskirts that is consistent withprevious results for galaxy clusters. The metal abundance profile shows a flatbehavior towards large radii, which is a hint for galactic winds as the primaryICM enrichment process. The entropy profile is consistent with numericalsimulations after applying a gas mass fraction correction. Previous analysesfor clusters and groups often showed an entropy flattening or even a droparound ${\sim} R_{200}$, which can be an indication of clumping ornon-equilibrium states in the outskirts. Such entropy behavior is absent inUGC03957. The gas mass fraction is well below the cosmic mean but rises abovethis value beyond $R_{200}$, which could be a hint for deviations fromhydrostatic equilibrium at these large radii. We determined the relative numberof different supernovae types and found that the abundance pattern can bedescribed by a relative contribution of 80% - 100% of core-collapse supernovae.This result is in agreement with previous measurements for galaxy groups.
