cds-question@unistra.frsupernovaevisible-astronomyspectroscopyredshiftedgalaxieschemical-abundancesabsolute-magnitudeinfrared-astronomyWe present a spectroscopic analysis of 44 low-luminosity host galaxies of Type Ia supernovae (SNe Ia) detected by the All-Sky Automated Survey for Supernovae (ASAS-SN), using hydrogen, oxygen, and sulfur emission lines to measure metallicities and star formation rates. We find no statistically significant evidence that the star formation activity and metallicities of the galaxies in our sample are inconsistent with galaxies of similar luminosities and masses. We identify two 3{sigma} outlier galaxies that have high metallicities for their stellar masses, but find that their other properties are consistent with general galaxies. The overall consistency between our sample and general galaxy samples further strengthens the evidence from more luminous SN Ia host galaxy samples that SN Ia host galaxies are typical.2023ApJ...950..108Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/950/108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : 2MASS All-Sky Extended Source Catalog (XSC) (IPAC/UMass, 2003-2006)II/328 : AllWISE Data Release (Cutri+ 2013)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/ApJ/560/566 : K-band galaxy LF from 2MASS (Kochanek+, 2001)J/A+A/459/85 : O/H & gas densities in star-forming galaxies (Nagao+, 2006)J/ApJS/178/247 : H{alpha} and [NII] survey in local 11 Mpc (Kennicutt+, 2008)J/ApJ/707/1449 : Local hosts of SNe Ia (Neill+, 2009)J/ApJ/722/566 : Host gal. of SNe Ia in SDSS-II SN survey (Lampeitl+, 2010)J/MNRAS/406/782 : Type Ia supernovae luminosities (Sullivan+, 2010)J/ApJ/770/107 : Host galaxies of SNIa from SNfactory (Childress+, 2013)J/MNRAS/438/1391 : Host galaxies of Type Ia SN from PTF (Pan+, 2014)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/MNRAS/448/732 : Type Ia SN environment within host gal.
