1992A&A...261L...1v Letter to the Editor The far-infrared/H{alpha} correlation of extreme IRAS galaxies A. C. van den Broek Astronomical Institute "Anton Pannekoek", University of Amsterdam, Kruislaan 403,1089 SJ Amsterdam, The Netherlands Received April 4,1991; accepted May 11,1992 Abstract. Using IRAS infrared data and H{alpha} CCD data for a sample of 38 far-infrared selected starburst galaxies with far-infrared luminosities ranging from 10^9^ to 5 10^11^ L_sun_, we find that the far- infrared and H{alpha} luminosities are correlated. The average value of log(L_FIR_/L^0^_H{alpha}_) equals 1.9+/-0.1. The H{alpha} luminosities have been corrected for reddening using H{alpha}/H{beta} line ratios. The relation between the far-infrared and uncorrected H{alpha} luminosities of optically selected normal galaxies and far-infrared selected starburst galaxies indicates that the dust absorption in H{alpha} increases smoothly with increasing luminosities. Application of a simple starburst model to the L_FIR_/L^0^_H{alpha}_ correlation indicates that in a starburst stars are formed up to masses of 60 M_sun_. Star formation rates derived for these starburst galaxies range from 0.3 to 300 M_sun_yr^-1^. Estimates of the available gas masses indicate that these star formation rates can be sustained for at least 10^8^ yr. Key words: dust, extinction - Galaxies: mass function - Galaxies: starburst
