Relations of stellar mass between electron temperature-based metallicity of star-forming galaxies in a wide mass range

WeiBin Shi, YanChun Liang, Xu Shao +7

We select 947 star-forming galaxies from SDSS-DR7 with [O~{\sc iii}]$\lambda$4363 emission lines detected at a signal-to-noise {ratio }larger than 5$\sigma$. Their electron temperatures and d…
