Star formation study of LSBs/STs galaxies

Although STs and LSBs have similar dynamical, stellar, and atomic hydrogen (H I) masses on an average, it is tricky to conclude if they constitute the same galaxy population, given the edge-on and face-on orientations of the STs and the LSBs, respectively.

We systematically study star formation rate (SFR) in a sample of STs and LSBs using SED fitting of photometric data in 10 bands including GALEX: FUV, NUV, SDSS : u,g,r,i,z and 2MASS : J, H, Ks using stellar population synthesis models employing the publicly available software MAGPHYS (Multi-Wavelength Analysis of Galaxy Physical Properties). The estimated median SFRs for LSBs and STs are 0.4^+2.2^_-0.3_ and 0.2^+0.9^_-0.2_ M_{Sun}_.yr^-1-^, respectively.
