Abstract:We examine and quantify how hybrid (e.g., UV+IR) star formation rate (SFR) estimators and the A_FUV_-{beta} relation depend on inclination for disk-dominated galaxies using spectral energy distribution modeling that utilizes the inclination-dependent attenuation curves described in Doore+ (2021ApJ...923...26D). We perform this analysis on a sample of 133 disk-dominated galaxies from the CANDELS fields and 18 disk galaxies from the Spitzer Infrared Nearby Galaxies Survey and Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel samples. We find that both the hybrid SFR estimators and the A_FUV_-{beta} relation present clear dependencies on inclination. To quantify this dependence in the hybrid SFR estimators, we derive an
