摘要

We present a narrow H alpha-band imaging survey of 357 low surface brightness galaxies (LSBGs) that are selected from the spring sky region of the 40% Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) H I Survey. All the H alpha images are obtained from the 2.16 m telescope, operated by the Xinglong Observatory of the National Astronomical Observatories, Chinese Academy of Sciences. We provide the H alpha fluxes and derive the global star formation rates (SFRs) of LSBGs after the Galactic extinction, internal extinction, and [N II] contamination correction. Compared to normal star-forming galaxies, LSBGs have a similar distribution in the H I surface density (Sigma(H I)), but their SFRs and star formation surface density (Sigma(SFR)) are much lower. Our results show that the gas-rich LSBGs selected from the ALFALFA survey obviously deviate from the Kennicutt-Schmidt law, in the relation between the star formation surface density (Sigma(SFR)) and the gas surface density (Sigma(gas)). However, they follow the extended Schmidt law well when taking the stellar mass of the galaxy into consideration.
