摘 要:By using Data Analysis Pipeline(DAP)products of Mapping Nearby Galaxies at Apache Point Observatory(MaNGA),which are publicly available from the SDSS Data Release 15,we analyze the local properties at the SN explosion sites and global properties of different types of SN host galaxies to explore the explosion environments of different types of *** our sample,there are 67 SN host galaxies in the field of view of MaNGA,including 32 Type Ia,29 core collapse SNe(CCSNe),1 superluminous SN(SLSN),1 Type I and 4 unclassified type of SNe,with which we can apply the K-S test for analysis and derive statistically robust *** to the limited sample size,we could not remove the mass dependence in this work,which is likely the true driver of the trends for the properties presented in this *** global star formation rate(SFR)and EW(H)for SN Ia hosts are slightly lower than those for CCSN hosts on *** Ia host galaxies are0.3 dex more massive than CCSN hosts,which implies that the number ratio of CCSNe to Type Ia SNe will decrease with increasing stellar mass of host *** stellar population age of SN Ia host galaxies is older than that of CCSN hosts on *** is no significant difference between different types of SN hosts for some properties,including local SFR density(SFR),and local and global gas-phase oxygen *** most galaxies in our sample,the global gas-phase oxygen abundance estimated from the integrated spectra of SN hosts can represent the local gas-phase oxygen abundance at the SN explosion sites with small bias.
